My research is in the areas of computer vision, machine learning and human visual perception. I am interested in scene and object recognition, among other things.

Scene and object recognition are two related visual tasks generally studied separately. However, by devising systems that solve these tasks in an integrated fashion I believe it is possible to build more efficient and robust recognition systems.

News

ADE20K dataset. 22.210 fully annotated images with objects and many with parts. A scene parsing challenge is being held jointly with ILSVRC'16. Winners will be invited to present at ILSVRC and COCO joint workshop at ECCV 2016. Check the scene parsing challenge website.

Multimodal scene recognition. The data for this work has thousands of linedrawings and textual descriptions of scenes, done by AMT workers. The dataset is organized with the same categories as the Places database.

Aligning books and movies. Learning to see and read by watching movies and reading books. Check also the MovieQA dataset: MovieQA: Story Understanding Benchmark.

Gaze following demo, and dataset. It follows the gaze of the people inside a picture or video and predicts what are they looking. In this video, frames are first processed independently and then the output is smoothed temporaly.

Places2 scene classification challenge, held in conjunction with ILSVRC at ICCV 2015.

Interactive visualization of deep networks: Places-CNN and ImageNet-CNN. For more details on understanding the internal representation built by a CNN trained for scene recognition: Object Detectors Emerge in Deep Scene CNNs.

Places database and scene recognition demo. The Places database contains 205 scene categories and 2,5 millions of images. More details about the demo appear in: "Learning Deep Features for Scene Recognition using Places Database," B. Zhou, A. Lapedriza, J. Xiao, A. Torralba, and A. Oliva. NIPS 2014 (pdf).

Saliency benchmark. It has 300 test images and fixations from 39 viewers. The fixations from 39 viewers per image are not public such that no model can be trained using this data set.

Check the LabelMe App for iPhone and iPad. The app connects with your LabelMe account online and allows you to take pictures and label them on the device. You can then recover the images and anotations with the LabelMe matlab toolbox. Developed by Josep Marc Mingot Hidalgo, Dolores Blanco, Aina Torralba, David Way and Antonio Torralba.
