Image Segmentation Tool


Image segmentation tool is a web-based application that divides an image into a given number of components and simplifies the image.




Kmeans

In this work, all similar points were clustered together and their values were substituted with the mean values which were calculated based on Kmeans clustering.


The objective function for Kmeans clustering could be written as:






xij are rgb values.


rij in {0, 1} assigned as 1 ,if only sample i assigned to cluster j. Otherwise, it is 0. At each iteration, in the first step, we keep the cluster centers fixed and assign each data point to the closest cluster center. This assignment could be written as:



We can form clusters S1 ,…, Sk using the value assigned to rij.
In the second step, we keep rij fixed and we minimize the objective function with respect to μk.




As long as the algorithm does not converge (algorithm converges when the assignments are not changed or maximum iteration reached), in both steps, we minimized the J.
