摘要： A filter system can effectively filter images with low computation cost by, instead of using large 2D filters, applying a series of smaller filters that require less compute and memory. In some implementations, the larger filter function, f, is replaced by f 1 , f 2 , ..., f N where f(x) ≈ f 1 ( x ) + f 2 ( x ) +... + f N ( x ) . The filter system can apply these filters sequentially across multiple frames in time. The time integration of information by the human visual system results in the perception of a single higher quality filtering result, while using only the compute and memory footprint necessary to implement the filters. The number of frames across which a filter can be split without introducing flicker artifacts is dependent on the refresh rate of the display.
