Stereo matching algorithms and multi camera reconstruction algorithms are usually compared using benchmarks. These benchmarks compare the quality of the resulting depth map or reconstructed surface mesh. We describe the differences between several known stereo and multi-view stereo benchmarks and their various datasets. Also the modifications that are necessary to use our own GPU based multi camera stereo matching algorithm with the data from these benchmarks are discussed.
We present the integration of two musical interfaces into a new music-making system that seeks to capture the experience of a choir and bring it into the mobile space. This system relies on three pervasive technologie...

In augmented reality, it is often necessary to draw the user's attention to particular objects in the real world without distracting her from her task. We explore the effectiveness of directing a user's attention by imperceptibly modifying existing features of a video. We present three user studies of the effects of applying a saliency modulation technique to video;evaluating modulation awareness, attention, and memory. Our results validate the saliency modulation technique as an alternative means to convey information to the user, suggesting attention shifts and influencing recall of selected regions without perceptible changes to visual input.

Given a set of axis-aligned boxes B = {B1,B2, . . . ,Bn} and a set of points P = {p1, p2, . . ., pm} in d-space, let the discrete measure of B with respect to P be defined as meas(B,P) = P ∩ { ∪ni=1 Bi}, namely, the...
Given a set of axis-aligned boxes B = {B1,B2, . . . ,Bn} and a set of points P = {p1, p2, . . ., pm} in d-space, let the discrete measure of B with respect to P be defined as meas(B,P) = P ∩ { ∪ni=1 Bi}, namely, the number of points of P contained in the union of boxes of B. This is a discrete and dynamic version of Klee's measure problem, which asks for the Euclidean volume of a union of boxes. Our result is a data structure for maintaining meas(B,P) under dynamic updates to both P and B, with O(log d n + m1-1/d ) time for each insert or delete operation in B, O(logd n + logm) time for each insert and O(logm) time for each delete operation in P, and O(1) time for the measure query. Our bound is slightly better than what can be achieved by applying a more general technique of Chan [3], but the primary appeal is that the method is simpler and more direct.
