New Framework for Enhanced the Image Visibility which is Degraded due to Fog and Weather Condition

Now-a-days digital camera is the most usually used devices to capture images. They are used all over the place, including mobile phone, personal digital assistant (PDAs), robots, watch and home security system. Few years back, the value of the images obtain from digital camera was not good. But in early days, there is no doubt that the value of the images has improved significantly. Part of this improvement is suitable to the higher dispensation capability of the system they are fixed and memory ease of use. The quality of image usually suffers from poor image quality, mainly lack of contrast and occurrence of shading and artifact, due to lack in focusing, lighting, specimen staining and other factor. Among these, contrast is one of factor. The research work aims at improving the contrast of images. They are many methods available for image enhancement but we have concentrated on contrast enhancement techniques in my work. We find that the need for contrast enhancement increases. Histogram Equalization is one of the method, this method is simple and comparative better than other. The contrast of an image is a feature which determines how image looks better visually. The Contrast enhancement is considered as one of the mainly important issue in image processing.
