Perceptual Science Group @ MIT

Founded in 1994, the Perceptual Science Group of the Department of Brain and Cognitive Sciences at MIT does research in human visual perception, machine vision, image processing, and human-computer interaction. Both the Adelson Lab and the Rosenholtz Lab are located in Building 32.

Lighting direction and translucency perception Bei's work on understanding the role of the lighting direction in translucency perception has been accepted to the Journal of Vision.

Taking a new look at subway map design: The Rosenholtz lab's Texture Tiling Model was used to evaluate subway maps for the MBTA Map Redesign Contest. Check out the FastCompany Design article, Visual.ly article, and the CSAIL news article. The news was also picked up by a couple other media sources: Smithsonian Magazine and The Dish. Here's an older article about our research from Science Daily.

Best presentation award at MIG 2013: Lavanya's presentation titled Simulated motion blur does not improve player experience in racing game won the Best Presentation award at the 2013 Motion in Games conference. This work was completed during her time at Disney Research, Pittsburgh.

Phase function and translucency perception: Bei's collaborative work on understanding the role of the phase function in the perception of translucent materials was presented at SIGGRAPH 2013. Check out the Cornell University news article.

Two papers accepted to ICCV 2013: Phillip's work on scene collages (Isola and Liu, Scene Collaging: Analysis and Synthesis of Natural Images with Semantic Layers) and Bei's study on fabrics (Bouman et al., Estimating the Material Properties of Fabric Through Observation of Motion) were both accepted for publication.

Dr. Bei Xiao accepts position at American University: Dr. Xiao begins her assistant professorship in the Department of Computer Science in Spring 2014!

Paper accepted to CVPR 2013: Rui's work on sensing surface textures with the GelSight sensor (Li and Adelson, Sensing and Recognizing Surface Textures Using a GelSight Sensor) was accepted for publication.

Dr. Krista Ehinger graduates: She successfully defended her thesis, Visual Features for Scene Recognition and Reorientation, on May 21st, 2013. Congratulations! She is continuing her research in Jeremy Wolfe's Lab. Here is a photo from the post-defense reception.

Two talks and three posters at VSS 2013: Lab members presented their work on pooling in high dimensions, visual conspicuity in eye movements, unifying models of crowding, texture statistics applied to scene perception, and tactile and visual matching of fabrics.

Paper accepted to World Haptics 2013: Xiaodan and Rui's work on lump detection with the GelSight sensor (Jia et al., Lump Detection with a GelSight Sensor) was accepted for publication.

Material recognition by computers: A journal paper based on Lavanya and Ce's work on material categorization was published in IJCV (Sharan et al., Recognizing Materials Using Perceptually Inspired Features).

Helping math students and sharks in Turkey: Derya donated more than 2,000 pounds of mathematics books and journals to the new library of the Nesin Mathematics Village near Şirince, Turkey. View the MIT News article! Additionally, she is working to raise awareness about shark conservation in Turkey.

Cuttlefish camouflage paper published: Check out Derya's paper (Quantification of cuttlefish (Sepia officinalis) camouflage: a study of color and luminance using in situ spectrometry. Akkaynak et al., Journal of Comparative Physiology A - 2012. DOI: 10.1007/s00359-012-0785-3).

Drs. Nathaniel Twarog and Alvin Raj graduate: Nat and Alvin successfully defended their graduate work on Higher-dimensional computational models of perceptual grouping and silhouette analysis and representation and Ambiguous statistics - how a statistical encoding in the periphery affects perception, respectively. Congratulations! Their theses can be found here and here. Here are pictures from their post-defense receptions.
