Abstract

The paper proposes a new computationally efficient technique for DCT operation. Unlike related research, the technique reduces the number of computations by predicting the effect of quantization on DCT and avoiding calculations of those DCT values which lead to zero elements in the block after quantization. Experimental evaluation on a number of video benchmarks shows that our method is able to reduce the total number of computations by 29% for DCT and by 59% for quantization while maintaining high image quality.
