Inverse quantization method for digital signals and images—area approximation type
Yoshinori Isomichi · Electronics and Communications in Japan (Part I Communications) · 1981
Abstract In transmitting and storing signals and images, the information content of the signals and images must be compressed using sampling and quantization techniques. This paper examines a generalization of the sampling theorem permitting a realistic observation window and proposes a new inverse quantization method suitable for this generalized sampling and usual quantization.
