Rearch On Enhancement Algorithm Of The Uneven Illumination Im Age

According to the uneven illumination image enhancement algorithm. Compared with the traditional Retinex algorithm for enhancement algorithm, the dynamic range compression, color fidelity and detail enhancement advantages in many aspects, this paper conducts the thorough research to the Retinex algorithm, and in view of the uneven illumination image enhancement algorithm is proposed for the class of images. Based on SSR algorithm is enhanced after treatment "halo" phenomenon and the variational framework of Retinex algorithm, the disadvantage of high complexity, in depth study of guided filtering, proposes non-uniform image enhancement algorithm based on Retinex guide filter light; for the MSR algorithm to solve the enhanced details and color fidelity between enhancement cannot balance and contrast noise amplification problem, put forward the uneven image enhancement algorithm based on multi-scale Retinex guide filter light; in depth study of the morphology theory and top hat transform based illumination uneven image extraction algorithm based on the objectives, the fusion of multi light treatment strategies suitable for uneven illumination preprocessing algorithm for license plate image.
