Title:
METHOD OF RESTORING AND RECONSTRUCTING SUPER-RESOLUTION IMAGE FROM LOW-RESOLUTION IMAGE SUBJECTED TO DATA COMPRESSION
Document Type and Number:
Japanese Patent JP2005020761
Kind Code:
A
Abstract:

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.

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.
