Image Segmentation Using Region Growing and Shrinking
Split and merge segmentation is an image processing technique used to segment an image. The image is successively split into quadrants based on a homogeneity criterion and similar regions are merged to create the segmented result. The technique incorporates a quadtree data structure, meaning that … See more • Define the criterion to be used for homogeneity • Split the image into equal size regions • Calculate homogeneity for each region See more The splitting results in a partitioned image as shown below to 3 levels. Each level of partitioning can be represented in a tree … See more After each split, a test is necessary to determine whether each new region needs further splitting. The criterion for the test is the homogeneity of the region. There are several ways to … See more The following example shows the segmentation of a gray scale image using matlab. The homogeneity criterion is thresholding, max(region)-min(region) < 10 for a region to be homogeneous. The blocks created during splitting are shown in the … See more Web17 Nov 2024 · I'm asked to segment an RGB image (hand) using split and merge segmentation Follow 103 views (last 30 days) Show older comments David Moheb on 17 Nov 2024 Commented: Image Analyst on 17 Nov 2024 Theme Copy function HandMask = SegmentHand (Img) Img = imread (Img); grayImg = rgb2gray (Img); rg = splitmerge … great outdoor play systems
