What "MICROCONTROLLER" that is best for IMAGE PROCESSING?

First of all, to perform visual inspection on an object or material it cannot be obscured or buried in a pile of trash, it must be separated or on top in full view, which requires some separation method. Full optical inspection may require viewing from multiple angles which requires multiple cameras or movement of the object. This implies visual inspection already requires more than just a camera and software to have any chance of success. There are some materials and objects that can be determined to be biodegradable by visual inspection, but there are many where visual inspection is simply inconclusive. Optical discrimination rate may be improved by adding extreme magnification and spectral analysis, which would still fall under the image processing umbrella, but may complicate the apparatus and material handling systems. For those object and materials that can be visually distinguished, performing the discrimination in software can be a very complex task and some choices will fail because the software is not sophisticated enough. So for general biodegradable decisions, image processing will not be very accurate, and many other sensor systems would be needed, working in concert, to improve accuracy.

However, there are special cases where image processing could be used successfully, and you might try one of these for your project. For example: image processing could distinguish whether an item is a cardboard cup or a plastic lid or a plastic straw, assuming these are the only types of trash on the conveyor.
