<p><P>PROBLEM TO BE SOLVED: To provide a restoring and/or reconstructing method for a super-resolution video image, in particular, a method of restoring and/or reconstructing a super-resolution image from low-resolution images compressed in a digital video recorder (DVR) environment or the like. <P>SOLUTION: The method 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 the 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 of an automobile) to reconstruct a super-resolution image. Consequently, an interest part of a low-resolution image stored in the DVR 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. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
