Abstract

In order to improve the effectiveness of remote sensing image enhancement, an enhancement algorithm based on multi-scale Retinex was presented and which can make up the deficiency of traditional wavelet algorithm that losing part information when image enhancement. The principle and realization methods of multi-scale Retinex and wavelet were calculated. The experiment of panchromatic and multicolor remote sensing image enhancement were carried out based on the two methods, the result showed that: the mean valve of enhanced image by this algorithm is about 125, the entropy and definition can be increased by 5% and 25% compared with wavelet algorithm, and remote sensing images could get better enhancement quality, so multi-scale Retinex is a better method for sensing image enhancement.
