Research of graph–based image segmentation algorithm
The methods of image segmentation, a process of division of an image into different segments which contain pixels of similar color, are considered. Graph-based segmentation algorithm, which is based on Kruskal’s algorithm is implemented in C++ language.
The main types of noise and filters that remove them from the image and analyze the apparent differences in the distribution of the image (using the watershed algorithm). Choosing the best filter to use when working with the watershed algorithm.
