Matlab – Point Functions and Histogram Image Segmentation

In image processing point operation or function results in new histogram different from the original image. It is basically taking average of several points and make it into one points such as b(i,j) = 10 round (A(i,j) / 10). You can clearly see the difference in histogram view. Image segmentation somehow related to point functions. A scene in an image composed of several different regions, object and etc. Segmentation is decomposition of an image into these regions or objects. As a human, we can easily identify each of object in an image. However, automatic segmentation using computer algorithm is difficult and right now consider unresolved. Automatic segmentation of image is still actively researched.  Continue reading “Matlab – Point Functions and Histogram Image Segmentation”
