Segmentation is an emerging process in the field of image processing and computer vision. It involves partitioning an image into a set of disjoint segments to represent image structures. This can be achieved us
In this paper, the segmentation algorithm based on SOM (self-organizing map) neural network with compression pre-processing by wavelet transform and image smoothing using Gaussian low-pass frequency domain filters is presented. Firstly, the input image is blurred using Gaussian low-pass frequency ...
A new object-oriented segmentation approach with special focus on shape analysis was developed for the extraction of large, man-made objects, especially agricultural fields, in high-resolution panchromatic satellite imagery. The approach, a combination of region- and edge-based techniques, includes new...
This paper addresses the problem of object tracking in a sequence of monocular images. The use of regions as primitives for tracking enables to directly handle consistent object-level entities. A motion-based segmentation process based on normal flows and first order motion models provide instantaneous...
Region-based image segmentation techniques make use of similarity in intensity, color and texture to determine the partitioning of an image. The powerful cue of contour continuity is not exploited at all. In this paper, we provide a way of incorporating curvilinear grouping into region-based image...

In this paper, a new region-based active contour model, named local region-based Chan–Vese (LRCV) model, for image segmentation is proposed. By introducing the local image information into the proposed model, the images with intensity inhomogeneity can be effectively segmented. At the same time...

2. Firstly, we generate initial candidate regions a well-known processing method: graph-based image segmentation. This method is also used by selective search method. Secondly, unsatisfied candidate regions are filtered. As we know, candidate regions whose length-width or width-length ratios are ...
