Digital Image Processing is very important area of research. A number of techniques are available for image enhancement of gray scale images. Important techniques namely Histogram Equalization, BBHE, RESWHE (recursion=2, gamma=No), AGCWD (Recursion=0, gamma=0) have been used quite frequently for image enhancement. But there are some shortcomings of the present techniques. To remove this shortcoming, a new hybrid technique namely REC+AGCWD (recursion=2, gamma=0 or 1) was proposed. The results of the proposed technique were compared with the existing techniques. In the present methodology, the brightness did not decrease during image enhancement. So the results and the technique was validated and accepted. The parameters via PSNR, MSE, AMBE etc. are taken for performance evaluation and validation of the proposed technique against the existing techniques. Keywords- Histogram Equalization (HE), BBHE, RESWHE, AGWCD, PSNR, MSE, Enhancement
