An improved multi scale medical image enhancement algorithm

The original DR image is decomposed into different scale and frequency of the band image sequence by using Laplace gaussian pyramid model methods. Using multi-scale image enhancement algorithm to enhance the High frequency component of the decomposed image, Then adjust the light of the low frequency part to make the reconstructed image illumination contrast more reasonable. The enhanced process according to different frequency layer image feature make the different gain weight for the different frequency layer image characteristics, so different frequency image layer realize respectively noise smoothing, dimensionality reduction and enhance the effect of edge character. The simulation experiments showed that this Image Processing Algorithm effect is very good.
