Feature-preserving lossy image compression using nonlinear PDEs
Tony Fan-Cheong Chan, Haomin Zhou · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
In this report, we propose combining the total variation denoising method with the high loss wavelet compression for high noise level images. Numerical experiments show that TV- denoising can bring more wavelet coefficients closer to zero thereby making the compression more efficient while the salient features of the image scan still be retained.
