Tool to select region on the image and split this region

I am currently using a Matlab code for waste detection using cameras. The code relies on deep learning , so before the user can immediatly detect the waste, he must train the applicatoin first. The training in this case is supervised training, so when an image is captured for training, there is an option to split the image. Then the image will split into 48 blocks and be saved in a folder. After that the user has to manually classify these blocks in folders.This is time consuming for the user. I want to create a tool that will ease training process so after the user capture image for training, he can select the waste part. Based on this selection the waste part will move to waste folder. Note that whatever the part was selected by the user, I still need this part to split into blocks and keep the original blocks format since the code is designed to train based on blocks of size (60 rows , 80 columns). I want to know if this is possible in matlab and if this is going to be a difficult task for someone with no background in image processing.

What do mena by select region? Is this complete region or some specific. If specific, then you have to figure out the feature of that region (Region Classifier or Image Segmentation).

Second part split the image to sub blocks, you can do that.
