My research is in the area of Computer Vision. I am interested in scene understanding.
I am a visiting researcher at the Massachusetts Institute of Technology (CSAIL, MIT), working with Prof. Antonio Torralba. I am also a member of the BCN Perceptual Computing Lab, the Computer Vision Center, and the Internet Interdisciplinary Institute (IN3)
Scene recognition demoGiven a picture our system predicts the scene category and some other attibutes. It also provides a heatmap that indicates the region of the image that supports the ouputs.
Understanding the representations learned by CNNsWe found that object detectors emerged in a CNN trained for scene recognition. For more information check our paper: B. Zhou, A. Khosla, A. Lapedriza, A. Oliva, and A. Torralba. “Object Detectors Emerge in Deep Scene CNNs.” International Conference on Learning Representations (ICLR) oral, 2015. (PDF).
