Abstract
A method compresses a set of correlated signals by first converting each signal to a sequence of integers, which are further organized as a set of bit-planes. An inverse accumulator is applied to each bit-plane to produce a bit-plane of shifted bits, which are permuted according to a predetermined permutation to produce bit-planes of permuted bits. Each bit-plane of permuted bits is partitioned into a set of blocks of bits. Syndrome bits are generated for each block of bits according to a rate-adaptive base code. Subsequently, the syndrome bits are decompressed in a decoder to recover the original correlated signals.
Claims20
A computerized method for extracting a matte from images acquired of a scene, comprising using a processor to perform the steps of:
- acquiring a foreground image focused at a foreground in a scene;
- acquiring a background image focused at a background in the scene;
- acquiring a pinhole image focused on the entire scene;
- comparing the pinhole image to the foreground image and the background image to extract a matte representing the scene.
A system for extracting a matte from images acquired of a scene, comprising:
- a foreground camera configured to acquire a foreground image focused at a foreground in a scene;
- a background camera configured to acquire a background image focused at a background in the scene;
- a pinhole camera configured to acquire a pinhole image focused on the entire scene;
- means for comparing the pinhole image to the foreground image and the background image to extract a matte representing the scene.
