Performance of an enhanced DCT compression system for space applications
Pen-Shu Yeh, Warner H. Miller, Shuang Hou · 2002
A low bit-rate data compression system utilizing a hybrid transform has been implemented for space applications. This hybrid transform reduces blocking distortion inherent in a 2D DCT and has smaller distortion measurement. The system also employs a developed adaptive entropy coder to reduce overhead associated with Huffman code tables. The performance of the system will be given along with its comparison with a JPEG compression system.
