PROBLEM TO BE SOLVED: To provide a method for performing distributed source coding (DSC (distributed information source coding)) of an image using a statistically correlated side information image.SOLUTION: In a decoder, a desired image is estimated by retrieving and extracting coding modes from an encoded side information image. For each bitplane in the encoded side information image, syndrome bits or parity bits are decoded to obtain an estimated bitplane of quantized transform coefficients of the desired image. Quantization and transform are applied to a prediction residual obtained using the coding modes. Decoding uses the quantized transform coefficients of the encoded side information image. The estimated bitplanes of the quantized transform coefficients of the desired image are combined to produce combined bitplanes. Then, inverse quantization, inverse transform and prediction based on the coding modes are applied to the combined bitplanes to recover an estimation value of the desired image. |
