Bananas Ripeness Detector & Classifier (Raw, Ripe, Overripe)

Bananas Ripeness Detector & Classifier (Raw, Ripe, Overripe)

This is a final project for Computer Vision course. The challenge is to make object detection without deep learning model. So I used rule based method such as color segmentation and contour detection. For each ROI's feature will be extract and classified using SVM. It succeed to detect multiple bananas in one image and classify it with high accuracy.
