Method of restoring and reconstructing a super-resolution image from a low-resolution compressed image

The present invention super-resolution (super-resolution) image reconstruction and / or relates to a reconstruction method, in particular a digital video recorder; to restore and / or reconstruct the compressed low-resolution image in the (DVR digital video recorder) environment with the super-resolution image relate to. The present invention is due to noise generated in the optical limit, and the number of pixels lacking limitations due spatial resolution, image compression, transmission and storing processes of CCD / CMOS image sensor according to the size of the camera in a digital video recorder (DVR) surveillance system, the video by removing the blur (blur) in the developing sequence, and allows the restoration and reconstruction of the low-resolution image to restore the high frequency components to the second resolution (in particular, the shooter of the garment or pulling the license plate number) image. As a result, the present invention generates the same effect as also to enable the expansion of the high-resolution as for the image of interest for the post of the low resolution stored in a digital video recorder, and use a low-resolution camera, the cost using expensive high-resolution camera thereby.
