IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, PRINT MEDIA AND RECORDING MEDIA Russian patent published in 2017 - IPC G06T5/20 H04N1/409 

FIELD: physics.

SUBSTANCE: image processing device is proposed comprising, at least, a storage module and a control module. The storage module includes a filter storage unit for storing a set of an approximation filter without an orientation and a filter bank having a degree or wavelet-frame having a degree set for the approximation filter without any orientation and a plurality of detailed filters with corresponding orientations, an image data storage module to store image data. The control module includes a decomposition module for receiving subband signals by performing decomposition for a plurality of resolutions for image data using a set of an approximation filter without an orientation or a filter bank or a wavelet-frame set for an approximation filter.

EFFECT: improving the quality of image processing by using an approximation filter.
