Image restoration technique mainly

Image restoration technique mainly for the imaging process "degraded" and put forward, and the imaging process "degraded" refers to the phenomenon of the main imaging system is affected by various factors, such as the defocusing of the imaging system between the device and the object is present relative movement inherent defects or other equipment, resulting in the image quality is not possible to achieve the desired requirements. Presence enhanced image restoration and image of similar places, it is also in order to improve the overall quality of the image. However, compared with the image restoration, image contrast enhancement technique focuses on stretching, its main purpose is to process the image in accordance with viewer preferences available, provided to the viewer receptive image, and the image restoration technology is by deblurring function of removing part of the image blur, reduction of the true image. The main mode is used to repair or reconstruction of the degraded image with some prior knowledge of the use of so-called degraded image, the recovery process point of view it can be seen as a reverse process of image degradation. Restored image, we must first be on the whole process of image degradation appropriate estimate, establish the approximate degradation mathematical model based on this, and then also need to model appropriate amendments to the distortion of the degradation process appeared compensated to ensure after the recovery of the resulting image close to the original image, optimize the image. But in the process of degradation of image blur, the noise and interference exist, which gives the restored image brought many uncertainties.
