Quantization noise of multilevel discrete wavelet transform filters in image processing

Quantization noise of multilevel discrete wavelet transform filters in image processing

The effect of the quantization noise of the coefficients of discrete wavelet transform (DWT) filters on the image processing result is analyzed. A multilevel DWT method is proposed for determining the effective bit-width of DWT filter coefficients at which quantization noise has little effect on the...
