A Novel Method for Low Illumination Image

Aiming at the low illumination image, we proposed a method to make images clearer which is based on our forward fog-removed method[7]. This method combines Multi-Scale Retinex(MSR) algorithm with wavelet transform algorithm. The improved method firstly use MSR algorithm to enhance the whole image, then the wavelet transform algorithm is used to strengthen the details information of image, finally a clearly image which has better overall contrast and more clear details information can be obtained. Through analyzing subjective and objective evaluation of the experimental results, the performance indicators of image which are processed by the proposed method in this paper are higher than those processed by other algorithms.
