Abstract

The optimal reconstruction is an advanced decoding technique for the transform-quantization image coding schemes such as JPEG. From the same encoded data, the image decoded by the optimal reconstruction has better quality than the conventional one. In particular, the optimal reconstruction does not suffer from the Gibbs artifact. The optimal reconstruction is formulated as a constrained optimization problem and solved by an evolution-projection algorithm.
