Paper Abstract

This paper introduces a novel algorithm for the enhancement of images of large dynamic range. In addition to dynamic range compression, the method provides control of brightness and contrast. The dynamic range compression is done in the spatial domain using the log transformation. Brightness and contrast control are done in the biorthogonal 9/7 wavelet transform domain. The algorithm can be easily added on to a JPEG2000 image compression system with only a modest increase in the computational complexity. Experimental results have shown comparable visual quality with the previously published Retinex algorithm.
