Wavelet Denoising Arithmetic Research Based on Small Hepatocellular Carcinoma CT Image
Early detection of small hepatocellular carcinoma (SHCC) has very important clinic value, and wavelet denoising arithmetic research of SHCC CT image, based on image processing technology, assists to diagnose the SHCC focus. According to the wavelet coefficient correlation, this article deducts, figures out and discards the feeble or irrelated coefficient of noise of SHCC CT image, and ultimately wipes off the noise.
