Object proposals have become a key component in most of the recent state-of-the-art object detectors, as they provide a reduced set of candidate locations for objects in the image. They allow, therefore, powerful machine learning algorithms (aka CNNs) to be applied in these scenarios. In this talk I will first present Multiscale Combinatorial Grouping (MCG) [1], a state-of-the-art object proposal and hierarchical segmentation technique. Then, I will describe some possible future lines of research in object proposal techniques by highlighting the new challenges faced by going from Pascal to COCO [2].
