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.

摘要： A method embeds a message into a document containing a set of glyphs. Individual glyphs in the document, groups of glyphs in the document, or the entire document are represented using a distance field that includes distance values from the shapes of interest. Each symbol of the message is represented as modifications of a subset of the distance values in the distance field. This subset of the distance values in the distance field is modified according to modification to produce a modified glyph in a modified document, wherein the symbol in the message is embedded in the modified glyph.

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.

摘要： A hash of signal is determining by dithering and scaling random projections of the signal. Then, the dithered and scaled random projections are quantized using a non-monotonic scalar quantizer to form the hash, and a privacy of the signal is preserved as long as parameters of the scaling, dithering and projections are only known by the determining and quantizing steps.
