TUAM P1.3 Transmission Noise Eliminations in BDPCM Image
Jae Jeong Hwang, Moon Ho Lee · 1993
We show that image compression possibilities of BDFCM which reduces information and increases correlation with signal-bhuring. Under the same! quantization steps, signal flow at the coder is analyzed and complete signal reconstruction pmperties m shown. Dynamic range characteristics of the diffms by the convenfional DPCM predictor are analyzed. In der to improve the median fihr that reduces impulse noise with blurring, adaptive filtexing for the differences is proposed. By means of the diffmce range, transmission impulse noises are detected and corrected by the filtering. “dore, low bit rate image dec with noise eliminations is proposed.
