Various implementations of region growing algorithm in image segmentation and Matlab source code
The region growing algorithm is a commonly used image segmentation method that classifies pixels with similar characteristics into the same region by gradually growing from a seed point. This article will introduce various implementation methods of the region growing algorithm in image segmentation, and provide the corresponding Matlab source code.
1. Basic region growing algorithm
The basic region growing algorithm is the simplest implementation. It starts from a seed point and traverses the image pixel by pixel, adding pixels with similar characteristics to the current region to the region. The following is the Matlab source code of the basic region growing algorithm:
function segmented_img = basic_region_growing(image, seed, threshold)
[rows, cols] = size(image)
