Abstarct: Images quality is especially important in various fields of application, Such as medical images, satellite images, industrial images, biometric images. Hence, using the various methods of image enhancement seems to be necessary for higher quality images. In this thesis, a new approach is presented for improving image quality. It provides a new outlook on how to apply the enhancement methods on images. In image capturing, issues such as the illumination of the scene and reflectance of objects affect on image captures. The effect of each of these issues on the resulting image can be considered as a separate component or image using homomorphic filter and they can be reviewed. Generally, the pixels value of an image is proportional to the illumination of point in the scene and the reflectance of the object. Hence, in this thesis, it is shown that impairment the image may be due to each of the illumination or reflectance component and various types of impairments have different effects on the illumination and reflectance of image components. Unlike conventional methods which do enhancement process on the original image for any type of impairment, in this thesis, enhancement of image is done on image components depending on the type of the impairment and it is to reduce the impairment effects from image components. According to results obtained and compare them with the results of existing enhancement methods, it can be expressed explicitly that image enhancement baxsed on the proposed method has better results comparing to applying enhancement methods on original image using existing methods.
