Matlab Image Processing Project.

We want to create a Matlab based waste segregator which will classify waste as dry or wet using only Image Processing (no sensors). The camera we want to connect is on Raspberry Pi 3 to capture images and we need min 4 wet and 4 dry objects and we take their samples and apply appropriate algorithm or filters (via image processing only) to create samples of those objects and store them in a database as wet and dry. Then we use camera to capture it and write a matlab code to compare that image after process it with the samples in our both databases dry and wet and the result will be flashed on screen as wet waste or dry waste along with audio sound. GUI will be preferred to make it easy. And the samples will be regular objects we use in our daily life. Also complete description and tutorial is expected with doubt solving.
