Abstract: Alpha images are efficiently encoded for inclusion in video bitstreams. During encoding, alpha image data is quantized as a first step before differential encoding. The quantized alpha image data is then differential encoded and represented in a modulo domain before entropy encoding to take advantage of certain distribution features of typical alpha image data. During decoding, a decoder performs differential decoding of encoded alpha image data before dequantization. During differential decoding, the data is converted from a modulo domain to a continuous domain. Dequantization is performed using a technique which results in reconstructed alpha image values which include 0 and maximal values within the acceptable alpha image data range so that the process preserves these values for reconstructed alpha images.
