Gaussian Markov random field model An efficient and robust type of unsupervised multispectral texture segmentation method is presented. Single decorrelated monospectral texture factors are assumed to be represented by a set of local Gaussian Markov random field (GMRF) models evaluated for each pixel centered image window and for each spectral band. The segmentation algorithm based on the underlying Gaussian mixture (GM) model operates in the decorrelated GMRF parametric space. The algorithm starts with an oversegmented initial estimation which is adaptively modified until the optimal number of homogeneous texture segments is reached. |

Unsupervised Segmentation of Color-Texture Regions in Images and Video A method for unsupervised segmentation of color-texture regions in images and video is presented. This method, which we refer to as JSEG, consists of two independent steps: color quantization and spatial segmentation. In the first step, colors in the image are quantized to several representative classes that can be used to differentiate regions in the image. The image pixels are then replaced by their corresponding color class labels, thus forming a class-map of the image. The focus of this work is on spatial segmentation, where a criterion for ?good? segmentation using the class-map is proposed. Applying the criterion to local windows in the class-map results in the J-image, in which high and low values correspond to possible boundaries and interiors of color-texture regions. A region growing method is then used to segment the image based on the multiscale J-images. A similar approach is applied to video sequences. An additional region tracking scheme is embedded into the region growing process to achieve consistent segmentation and tracking results, even for scenes with nonrigid object motion. Experiments show the robustness of the JSEG algorithm on real images and video. |

Texture Fragmentation and Reconstruction The Texture Fragmentation and Reconstruction (TFR) segmentation algorithm is based on a texture modeling particularly suited for segmentation in an unsupervised framework. A texture is regarded for each fixed spatial direction as a finite-state Markov chain where the states of the process are quantized colors. On the basis of this modeling, a simple segmentation algorithm is derived that precesses independently color and spatial information, by first performing a color-based clustering, which provides the quantized colors, and then by means of a further spatial-based clustering, which separates regions according to their transition probability profile. Finally, a region merging algorithm allows to recover the different textures, that is to recompose their internal Markov chains. |

Efficient Graph-Based Image Segmentation We define a predicate for measuring the evidence for a boundary between two regions using a graph-based representation of the image. We then develop an efficient segmentation algorithm based on this predicate, and show that although this algorithm makes greedy decisions it produces segmentations that satisfy global properties. We apply the algorithm to image segmentation using two different kinds of local neighborhoods in constructing the graph, and illustrate the results with both real and synthetic images. The algorithm runs in time nearly linear in the number of graph edges and is also fast in practice. An important characteristic of the method is its ability to preserve detail in low-variability image regions while ignoring detail in high-variability regions. |

HGS algorithm The HGS unsupervised segmenter is based on the integration of the Gabor filters with the measurement of color. Single versions of the method differ in their photometric invariance power (HGS-E no invariance, HGS-W low, HGS-C full invariance). The spatial frequency is measured by sampling the incoming image with a shifted Gaussian in the spatial frequency domain, and the color is measured by sampling the signal with Gaussian in wavelength domain. The method implies that the color-texture is measured in the wavelength-Fourier domain. The measurement filter in this domain boils down to a 3D Gaussian, representing a Gabor-Gaussian in the spatial-color domain. |

The algorithm provides a sequence of nested segmentation maps which allow the analysis at various scales of observation. However, the performance which is very good at large scales, with complex semantic areas retrieved with remarkable accuracy, becomes less satisfactory at finer scales. By using the TFR in a recursive fashion, segmenting the image in just two regions, initially, with each region further segmented only if relevant subregions emerge, we get the Recursive TFR (R-TFR). R-TFR allows one to better adapt to local statistics and to extract significant textures also at finer scales. In this version the best segmentation scale is manually selected. |

Gaussian Markov random field based improved texture descriptor for image segmentation An improved semi parametric method of texture feature formulation using GMRFs. Texture descriptor based on Gaussian Markov random fields (GMRFs). A spatially localized parameter estimation technique using local linear regression is performed and the distributions of local parameter estimates are constructed to formulate the texture features. The inconsistencies arising in localized parameter estimation are addressed by applying generalized inverse, regularization and an estimation window size selection criterion. The texture descriptors are named as local parameter histograms (LPHs) and are used in texture segmentation with the k-means clustering algorithm. The segmentation results on general texture datasets demonstrate that LPH descriptors significantly improve the performance of classical GMRF features and achieve better results compared to the state-of-the-art texture descriptors based on local feature distributions. |

The image is recursively segmented in smaller and smaller regions until a stopping condition, local to each region, is met. Each elementary binary segmentation is obtained as the solution of a MAP estimation problem, with the region prior modeled as an MRF. Since only binary fields are used, and thanks to the tree structure, the algorithm is quite fast, and allows one to address the cluster validation problem in a seamless way. In addition, all field parameters are estimated locally, allowing for some spatial adaptivity. In this version the proper segmentation scale (tree pruning) is left to the user. |

However, a single model/segmenter cannot fit regions with wildly different nature, and one should be allowed to select in a suitable library the tool most suited to the local statistics. The dynamic segmentation/classification algorithm (DHC), uses two segmenters, based on spectral and textural properties, respectively, and a suitable rule for switching model locally. In this version the segmentation is hand-picked from the hierarchical segmentation stack. |

Texture Segmentation Based on Voting of Blocks, Bayesian Flooding and Region Merging We propose an unsupervised texture image segmentation framework with unknown number of regions, which involves feature extraction and classification in feature space, followed by flooding and merging in spatial domain. The distribution of the features for the different classes are obtained by a block-wise unsupervised voting framework using the blocks grid graph or its minimum spanning tree and the Mallows distance. The final clustering is obtained by using the k-centroids algorithm. An efficient flooding algorithm is used, namely, Priority Multi-Class Flooding Algorithm (PMCFA), that assign pixels to labels using Bayesian dissimilarity criteria. Finally, a region merging method, which incorporates boundary information, is introduced for obtaining the final segmentation map. The proposed scheme is executed for several number of regions, we select the number of regions that minimize a criterion that takes into account the average likelihood per pixel of the classification map and penalizes the complexity of the regions boundaries. Segmentation results on the Prague benchmark data set demonstrate the high performance of the proposed scheme. |

Single regions with dynamic textures can furthermore dynamically change their location as well as their shape. Individual dynamic multispectral texture mosaic frames are locally represented by Markovian features derived from four directional multispectral Markovian models recursively evaluated for each pixel site. Estimated frame-based Markovian parametric spaces are segmented using an unsupervised segmenter derived from the Gaussian mixture model data representation which exploits contextual information from previous video frames segmentation history. The segmentation algorithm for every frame starts with an over segmented initial estimation which is adaptively modified until the optimal number of homogeneous texture segments is reached. |

Local Binary Pattern (LBP) is a simple yet very efficient texture operator which labels the pixels of an image by thresholding the neighborhood of each pixel and considers the result as a binary number. Due to its discriminative power and computational simplicity, LBP texture operator has become a popular approach in various applications. It can be seen as a unifying approach to the traditionally divergent statistical and structural models of texture analysis. |

A Global/Local Affinity Graph for Image Segmentation Construction of a reliable graph capturing perceptual grouping cues of an image is fundamental for graph-cut based image segmentation methods. We propose a novel sparse global/local affinity graph over superpixels of an input image to capture both short and long range grouping cues, thereby enabling perceptual grouping laws, e.g., proximity, similarity, continuity, to enter in action through a suitable graph cut algorithm. Moreover, we also evaluate three major visual features, namely color, texture and shape, for their effectiveness in perceptual segmentation and propose a simple graph fusion scheme to implement some recent findings from psychophysics which suggest combining these visual features with different emphases for perceptual grouping. Specifically, an input image is first oversegmented into superpixels at different scales. We postulate a gravitation law based on empirical observations and divide superpixels adaptively into small, medium and large sized sets. Global grouping is achieved using medium sized superpixels through a sparse representation of superpixels' features by solving a `0-minimization problem, thereby enabling continuity or propagation of local smoothness over long range connections. Small and large sized superpixels are then used to achieve local smoothness through an adjacent graph in a given feature space, thus implementing perceptual laws, e.g., similarity and proximity. Finally, a bipartite graph is also introduced to enable propagation of grouping cues between superpixels of different scales. |

Natural Image Segmentation with Adaptive Texture and Boundary Encoding Algorithm for unsupervised segmentation of natural images that harnesses the principle of minimum description length (MDL). The method is based on observations that a homogeneously textured region of a natural image can be well modeled by a Gaussian distribution and the region boundary can be effectively coded by an adaptive chain code. The optimal segmentation of an image is the one that gives the shortest coding length for encoding all textures and boundaries in the image, and is obtained via an agglomerative clustering process applied to a hierarchy of decreasing window sizes. The optimal segmentation also provides an accurate estimate of the overall coding length and hence the true entropy of the image. |

Model-based learning of local image features for unsupervised texture segmentation Features that capture well the textural patterns of a certain class of images are crucial for the performance of texture segmentation methods. The manual selection of features or designing new ones can be a tedious task. Therefore, it is desirable to automatically adapt the features to a certain image or class of images. Typically, this requires a large set of training images with similar textures and ground truth segmentation. In this paper, we propose a framework to learn features for texture segmentation when no such training data is available. The cost function for our learning process is constructed to match a commonly used segmentation model, the piecewise constant Mumford-Shah model. This means that the features are learned such that they provide an approximately piecewise constant feature image with a small jump set. Based on this idea, we develop a two-stage algorithm which first learns suitable convolutional features and then performs segmentation. We note that the features can be learned from a small set of images, from a single image, or even from image patches. The proposed method achieves a competitive rank in the Prague texture segmentation benchmark, and it is effective for segmenting histological images. |

In this work we use the combination of global and local coherent. Find the sufficient number of clusters do by using histograms and probability theory, on the next part we use the metric space strategies to model local intensity feature of input image. Some problems in this method are from two main sources, wrong number of cluster estimation and the other one is the modeling method failures.
