Abstract

The apparatus is designed for use in enhancing the complex texture details of digital image in real-time. It comprises a memory module, a phase-locking/shift circuit, a fractional order differential mask convolution circuit and a maximum value comparator. In the fractional order differential mask convolution circuit, the operation rules of 8 dedicated algorithm circuits use fractional order differential mask convolution scheme to achieve the spatial filter of digital image fractional order differential coefficient. The invention can be used in HDTV, biomedicine image, bank paper, satellite remote sensing, and creature characteristic graph.

Description

[0001] Field [0002] The digital image fractional differential filter proposed by the present invention is a signal processing circuit device for real-time enhancement of complex texture details of digital images. The order of the fractional differential involved in the present invention is not a traditional integer order, but a non-integer order, and fractions or rational decimals are generally used in engineering applications. See figure 1 , the fractional order differential filter of this digital image adopts digital video popular memory group 18, phase lock / shift circuit group 19, fractional order differential mask convolution circuit 20 and maximum value comparator 21 to constitute in cascade mode . The operating rules of the 8 specific algorithm unit circuits 1-8 in its fractional differential mask convolution circuit 20 are to use the scheme of fractional differential mask convolution to realize spatial filtering of digital image fractional differential. The digital i...
