CPC Code(s): G06T5/20
Abstract: 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, �, is replaced by �, �, . . . , �where �(x)≈�(x)+�(x)+ . . . +�(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.
