摘要： An encoded signal is decoded based on statistical dependencies between the encoded signal and the side information. A statistical reliability of each transform block of the side information is determined as a function of absolute values of transform coefficients of a transform block. The transform blocks of the side information are grouped into a set of groups based on the statistical reliability of each transform block. The decoding is performed using a statistical dependency between a transform block of the encoded signal and a group including a corresponding transform block of the side information.

For each bitplane in a most to least significant order, the method include obtaining a list of significant pixels (LSP), a list of insignificant pixels (LIP), and a list of insignificant sets (LIS) according to a hierarchical ordering of the source image pixels; synchronizing the LSP, LIP and LIS of the source image with the LSP, LIP and LIS of a key image; constructing a temporary list of insignificant sets (TLIS) for the source image; and applying syndrome encoding to the LSP, LIP, and TLIS of the source image to obtain syndromes corresponding to magnitudes and signs of pixels in the source image, wherein the steps are performed in a processor.

摘要： Scale-invariant features are extracted from an image. The features are projected to a lower dimensional random projection matrix by multiplying the features by a matrix of random entries. The matrix of random projections is quantized to produce a matrix of quantization indices, which form a query vector for searching a database of images to retrieve metadata related to the image.
