GRAB: generalized region assigned to binary

GRAB: generalized region assigned to binary

Scale is one of the major challenges in recognition problems. For example, a face captured across large distances is considerably harder to recognize than the same face at small distances. Local binary pattern (LBP) and its variants have been successfully used in face detection, recognition, and many other computer vision applications. While LBP features are shown to be discriminative in face r...

Noisy Generalized Binary Search

This paper addresses the problem of noisy Generalized Binary Search (GBS). GBS is a well-known greedy algorithm for determining a binary-valued hypothesis through a sequence of strategically selected queries. At each step, a query is selected that most evenly splits the hypotheses under consideration into two disjoint subsets, a natural generalization of the idea underlying classic binary searc...

Who Expressed What Emotion? Men Grab Anger, Women Grab Happiness.

When anger or happiness flashes on a face in the crowd, do we misperceive that emotion as belonging to someone else? Two studies found that misperception of apparent emotional expressions - "illusory conjunctions" - depended on the gender of the target: male faces tended to "grab" anger from neighboring faces, and female faces tended to grab happiness. Importantly, the evidence did not suggest ...

The flash grab effect

When an object moves back and forth, its trajectory appears significantly shorter than it actually is. The object appears to stop and reverse well before its actual reversal point, as if there is some averaging of location within a window of about 100 ms (Sinico et al., 2009). Surprisingly, if a bar is flashed at the physical end point of the trajectory, right on top of the object, just as it r...
