Abstract :
A transform coding scheme has been widely used in the field of image data compression. A lot of computational power is required for the realtime operation. A new fast computational algorithm, pruned transform coding (PTC), which can reduce the computational complexity compared with the conventional transform coding is proposed. Excellent coding performance is demonstrated through a computer simulation.
