A new satellite image contrast enhancement technique based on discrete wavelet transform (DWT) and singular value decomposition (SVD) are proposed. The technique decomposes the image into four input frequencies for subband decomposition by using discrete wavelet transform and estimated low noise—— Then, it is compared with the conventional image equalization techniques, such as general histogram equalization and local histogram equalization, and brightness preserving dynamic histogram equalization and singular value equalization. The experimental results show that this method is superior to conventional and advanced technology.
