Explore MATLAB source code curated for "高频信息" with clean implementations, documentation, and examples.
Performing Fast Fourier Transform on images, removing high-frequency information in the frequency domain, and applying inverse transform to spatial domain to eliminate image raster artifacts with implementation insights.
Conventional wavelet threshold denoising methods operate under the assumption that wavelet coefficients are independent, neglecting their correlations across adjacent scales, which results in an inherent trade-off between noise removal and preservation of useful high-frequency information.
This program implements image enhancement through a fuzzy enhancement algorithm, significantly improving edge information visibility and optimizing high-frequency information processing for superior image quality and detail preservation.
