Image Noise Removal via Wavelet Transform and r/K-PSO

Image noise removal is a classic problem. In this paper, a novel scheme combining r/K-PSO and wavelet transform was introduced to removal image noise. By wavelet transform, image was decomposed into detail subbands and approximation subband. Every detail subband will be shrunk by a special threshold...
