Abstract |
|
This paper represents the basic techniques to enhance image. The methods of image enhancement improves the quality of image. Due to uneven illumination image doesnot perceived as good as it shoud be. Firstly image enhancement , spatial and frequency domains, point processing, image negatives,contrast stretching are explained. Then histogram processing , histogram equalization with results, local enhancement are discussed. Then various smoothening and sharpening filters are discussed. The proposed method works by applying thresholding to illuminance which separates the image into different portions according to illuminance variance. After that only that part has been enhanced which has lower illuminance value. |
