We present an algorithm for finding correspondences in epipolar plane images (EPIs). An EPI is a 2-dimensional spatio-temporal image obtained from a dense image sequence that is rectified so that each scene point is projected to the same row in all frames. Scenes with opaque Lambertian surfaces without occlusions are assumed. The approach is based on finding lines with similar intensities in an...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
