A new spatial frequency analysis method based on wavelet was applied to homomorphic filtering to enhance the contrast of ICT image.

The method has been applied to the practical ICT image processing systems and the image quality is improved,the accuracy of the lacuna detection is improved.

A blade wall thickness precision measurement method based on ICT image with sub-pixel accuracy is researched to satisfy this requirement.

X-ray medical image enhancement and histogram processing methods based on Matlab;

Medical image enhancement based on neural dynamics;

A new image enhancement method for retinal vascular images based on morphology and matched filters;

An image enhancing method based on mathematical morphology;

Parallel Image Enhancing Research Based on PDE;

Image Enhancing and Extracting Core Point of Fingerprint;

Realization of image enhance with FFT under VC~(＋＋);

A lot of researchers usually focus on the effectiveness of different image enhancement algorithms in given circumstances.

It can be got more ideal image enhance outcome by intensity expand (improve a contrast ratio), adaptive filter (dislodge “salt”noise), discrete wavelet transform (border strengthening) and combining with several methods of image enhance arithmetic than using image disposing so.
