region growing by pixel aggregation in digital image

An Image Segmentation Algorithm Research Based on Region

INTRODUCTION. Image segmentation is the critical first steps of the image processing to image analysis, its goal is that the digital image is divided into several regions, which have certain common properties of disjoint regions, the target and background is separation, these provide the basis for subsequent processing of computer vision (Lin et al., 2005).

Region growing

Region growing is a simple region-based image segmentation method. It is also classified as a pixel-based image segmentation method since it involves the selection of initial seed points. This approach to segmentation examines neighboring pixels of initial seed points and determines whether the pixel neighbors should be added to the region. The process is iterated on, in the same manner as general data clustering algorithms. A general discussion of the region Get price

Introduction to Image Segmentation with K

Jul 29, 2019Image Segmentation involves converting an image into a collection of regions of pixels that are represented by a mask or a labeled image. By dividing an image into segments, you can process only the important segments of the image instead of processing the entire image. Some techniques that follow this approach are region growing Get price

Linear

The goal of segmentation is to partition a digital image or curve into segments such that the points in each segment share a common property. For example, we can partition a curve into connected subsets such that the points of each subset lie on a common straight line, or we can partition an image such that intensity function is linearly varying when restricted to ne part.
