A new fully automated deep learning-based framework is proposed in this work using MASK-RCNN and TL based retraining for features extraction. The key steps are: (i) contrast stretching; (ii) MASK-RCNN based lesion segmentation and extraction; (iii) feature extraction by employing the concept of transfer learning; (iv) selection of most discriminant features and finally classification The transfer learning approach is to train a base network and then copy its first layers of the target. My base network is resnet50 and I copied the first layers to Mask RCNN. So, why do I need pre-trained weights, for example, coco pre-trained weights
