Analysis of the Quantization Noise in Discrete Wavelet Transform Filters for Image Processing
Electronics, 2018 In this paper, we analyze the noise quantization effects in coefficients of discrete wavelet transform (DWT) filter banks for image processing. We propose the implementation of the DWT method, making it possible to determine the effective bit-width of ...

Impact Analysis of Baseband Quantizer on Coding Efficiency for HDR Video
, 2016 Digitally acquired high dynamic range (HDR) video baseband signal can take 10 to 12 bits per color channel. It is economically important to be able to reuse the legacy 8 or 10-bit video codecs to efficiently compress the HDR video.
