Image Enhancement in Remote Sensing Application using Modified Dual Tree DWT

In this paper, Enhancement of image in remote sensing application using modified Dual tree DWT technique has been proposed. The technique decomposes the input image into the number of frequency sub bands by using DWT and estimates the values using many decomposition levels in sub-band image, and then, it reconstructs the enhanced image by applying inverse DWT. The technique is compared with conventional techniques such as standard wavelet transforms to enhance the image brightness and easy to find the objects present in it. The experimental results show the superiority of the proposed method over conventional method.
