摘要
This paper analyzes the appearance of creases and light non-uniformity in scanned topographic maps, and applies the Retinex theory to process the maps. A processing method and a single-scale Retinex algorithm (SSR) are proposed based on the faster Fourier transform in the west (FFTW) and the Retinex theory. Experimental results show that the proposed method can overcome disadvantages of the mathematical model and effectively remove creases and light non-uniformity in scanned topographic maps.
