Abstract |
|
Contrast enhancement deals those images which have lower resolution. In order to increase information associated with the image details. Here we represent a new algorithm to enhance contrast of the image. The algorithm is applied on 2D-DCT domain to enhance contrast and hence enhance the various image details. The advantages of the algorithm are it avoids severe blocking artifacts and also avoids amplification of low intensity noise. The method is applied on the decompression mode of the JPEG codec. |
