The Image Enhancement Technology Based On DSP

An image system consists of acquisition, transmission, reception and display, every part of which can be disturbed, so that the image quality can be degraded. Elementary requirement of image enhancement is how to deal with these degraded images to meet our need. One of main contents of image processing is image enhancement; it is an important link in the image processing system. Moreover, its result has direct relations with the high-level process and relations with understand of the image.This article in the exposition image intensification processing essential method's foundation made the improvement to some tradition's method and has realized the histogram balancing and the strengthened detail histogram balanced algorithm image intensification with DSP.We introduce the theory and methods of wavelet de-noising, including rationale and methods of wavelet de-noising and wavelet thresholding. At the same time, we show several wavelet thresholding functions, the method of threshold estimation and the evaluatable criterion of the de-noising results based on Visual C++.This paper uses the high speed operation ability of DSP, to meet the real time dynamic emulation of image enhancement, realizes the real time mange process of the image enhancement, on the DSP EVM emulation plat, it used the TMS320C6711B as the core processor.
