Image enhancement based on wavelet transformation and pseudo-color coding with phase-modulated image density processing

Wavelet transformation based on image enhancement technique is only applicable to black-and-white image, and pseudo-color image processing technology cannot adequately deal with some of the image details. In this paper, an enhanced approach for black-and-white image based on wavelet analysis and a new pseudo-color image processing is presented. This method has great rich levels and its definition of algorithm is 50% higher than traditional methods. In addition, this method can process high gray resolution image and select the best performing coloring scheme. The rate improvement of information entropy up to 30% has been achieved by using this method.
