We presented a new experimental teaching system for digital image processing course. The students may design programs about image processing methods and submit the experimental data to database in the system. The system may automatically grade students' experimental results. The teacher can use handmade perusal. The system can educate students' ability of study and design. It may raise teacher's working...
This article uses the advanced wavelet theory to perform multi-criteria transformation on the medical CT image wavelet in order to obtain directive components. The improved wavelet threshold value law is combined with the wavelet homomorphism filter corresponding to the obtained directive components to remove noise and enhance image effect, finally resulting in the multi-scale (level) enhanced images...
