....The objectives pursued in each application condition the kind of regions to be extracted and, as a result, the kind of technique to be used. For this reason no general segmentation theory exists, but a series of different segmentation techniques, each of them with benefits and drawbacks [HAR85]. Two major approaches to segmentation are distinguished [NEV86] Region based methods: Region based methods try to find areas in the intensity image with homogeneous properties, which in turn give the boundaries. Edge based methods: In edge based methods, the local discontinuities are ....
....dependent, simple model based inspection systems operate on edges without parametrisation) These two methods are complementary and the decision which of the methods should be used is application dependent. For a detailed discussion of segmentation techniques, the reader is referred to [ROS82,HAR85,DAL91,JAI90,TOR92]. 2.4.4 Edge Detection and Operator Evaluation Edge detection is based on the assumption that at an edge the intensity in an image changes in a discontinuous way. In two dimensions, the edges have a direction and a magnitude, and their intensity profile is assumed to be uniform along the edge ....

....about this fact, we developed a new adaptive region growing method. Our method learns its homogeneity criterion on a model of regions and their homogeneity while searching for the region. As criterion for the homogeneity we use the gray value of the region and standard deviation, similar to [16,17], assuming that the variation of the gray values within regions is smaller than that between regions. We think that the model is robust because the homogeneity criterion contains only information about the region itself. 2. DERIVATION OF THE HOMOGENEITY MODEL FROM MEDICAL IMAGES The objective of ....
....distribution of gray values with a given mean and standard deviation. The mean is the absorption value of the tissue in CT images and the magnetization in MR images. The standard deviation accounts for variations due to noise (this criterion was used as homogeneity measure by other authors, e.g. [16, 17]) The effects of the PVE can be captured in an approximative fashion by assuming different standard deviations for gray values that are higher or lower than the mean. The appropriateness of this model was tested by investigating grey level distributions of CTs and MRs of the abdomen along a ....

....Index Terms Nonparametric probability model, region competition, region growing, scale space based classification, segmentation. I INTRODUCTION MAGE segmentation is a long standing problem in com .puter vision. Generally speaking, there are five main approaches to image segmentation [16], 23] namely, measurement space guided spatial clustering methods, boundary based methods, region based methods, global optimization approaches, and hybrid techniques which combine boundary and region criteria. Measurement space guided spatial clustering methods are based on the assumption that ....

....of the implementation carried out. IV. Segmentation Image segmentation is an essential process for most sub sequent image processing tasks such as image description and recognition, 3D reconstruction, visualization and com pression. Many techniques have been proposed for image segmentation [25][11]. These techniques can be grouped into major categories such as edge based, region based, Markov Random Field based (MRF) Deformable Models, and Hybrid techniques. Edge and Region based techniques: In the first group, image edges must be detected and grouped into contours or surfaces which ....

....which an image is divided into constituent objects or parts. It is often the first and most vital step in an image analysis task. Effective segmentation can usually dictate eventual success of the analysis. For this reason, many segmentation techniques have been developed by researchers worldwide [6]. Segmentation of intensity images usually involve four main approaches, namely thresholding, boundary detection, region based and hybrid methods. Thresholding techniques [12] are based on the postulate that all pixel whose value lie within a certain range belongs to one class. Such methods ....

....in a DWPF tree. 4 Experimental results for multi channel texture segmentation Segmentation algorithms accept as input a set of features and output a consistent labeling for each pixel. Fundamentally, this can be considered a multi dimensional data clustering problem. As pointed out by Haralick [39], at present no general algorithms exist for this problem. Clustering algorithms that have been previously used for texture segmentation can be divided into two categories: supervised segmentation and unsupervised segmentation. For practical applications, unsupervised segmentation is desirable ....

....is used for the segmentation process which is often neglected in the literature [1] A hierarchical approach enables effective predictive coding and object based data access. 2.1. Intraframe Segmentation The intraframe segmentation is based on a combination of centroid linkage region growing [2] and DRF edge detection [3] Let f(x) Y (x) U(x) V (x) T be the colour of the image at position x. The region growing process combines adjacent pixels with similar colour to regions R. For simplicity this is done by comparing the mean colour of a region with the colour of the pixel that ....
