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

InactiveUS20050019000A1Preserving contourRemove image blurImage enhancementTelevision system detailsDigital videoImage compression
Provided is a method of restoring and / or reconstructing a super-resolution image from low-resolution images compressed in a digital video recorder (DVR) environment. The present invention can remove a blur of a video sequence, caused by optical limitations due to a miniaturized camera of a digital video recorder monitoring system, a limitation of spatial resolution due to an insufficient number of pixels of a CCD / CMOS image sensor, and noises generated during image compression, transmission and storing processes, to restore high-frequency components of low-resolution images (for example, the face and appearance of a suspect or numbers of a number plate) to reconstruct a super-resolution image. Consequently, an interest part of a low-resolution image stored in the digital video recorder can be magnified to a high-resolution image later, and the effect of an expensive high-performance camera can be obtained from an inexpensive low-performance camera.
