Hardware implementation guided filtering optimization system and method

The invention provides a hardware implementation guided filtering optimization system and a method. The problem that the guided filtering algorithm has poor real-time performance, large area and high power consumption in hardware implementation is solved. The hardware implementation guided filtering optimization system comprises, according to the data flow, a mean filter module, a data synchronizer, a variance calculation module, a monomial coefficient calculation module, a constant term calculation module, a monomial coefficient mean filter module, a constant term mean filter module, and an output stage calculation module. The guided filtering optimization method comprises the following steps: generating a local image through serial input; synchronizing image data; carrying out mean filtering based on the division characteristic of a shift-right register, and calculating the variance; synchronizing data; calculating the monomial coefficient and the constant term in guided filtering, and carrying out mean fil
