Image processing by using Scilab only

This project must be done by using the Scilab program with Image Segmentation. The following will be the task to be accomplished: [login to view URL] an image for initial work (Tiger). write a Scilab code that will segment the animal from the background just like I send you an example to see what I mean). In the process, you might have 3 regions i.e. animal, land, and sky or just two regions animal and land. [login to view URL] sure each region is marked with different colors. [login to view URL] then may choose another image (Giraffe) to check whether your code can be generalized to this image or not. Note: when you write the code I want some comments as clarification (// and describe why to put this instruction or the number) 4. You need to teach me how to run the code and show the results.
