Abstract: Image enhancement is a process which performs some operation on the image in order to obtain high contrast images with better quality by suppressing the noisy pixels. Quality of the image is a satisfactory part of any image enhancement technique. Consequently, several techniques till now have been proposing to acquire high quality image while performing different operations. Traditional techniques are not able to preserve the edges of the image which degrades the quality of the image and no longer able to use for other purposes. Owing to this a new technique has proposed which makes quality oriented image after enhancing contrast. A hybrid technique has applied on the image which considers every part of the image and preserves edges too. The proposed method provides good result in terms of different images i.e. gray scale or RGB color images as compared to traditional techniques. Experiments have performed to estimate the performance of the proposed technique visually.
