Abstract
This project presents an approach of segmenting an image by dividing it into multiple regions or fragments. Region growing is based on selecting initial seed points and adding neighboring pixels to the region depending on the suitable membership criteria such as color similarity. Initially seed regions are identified based on calculation of variance of R, G and B components and selecting the first seedpoint having the minimum R, G, B variance product. 4 connected neighbors are used to grow from the seed point. This process runs iteratively until no change is found in two successive stages. Experimental results on a number of images demonstrate the effectiveness of the technique. A comparison of this approach with meanshift segmentation is also presented.
