ADAPTIVE FILTERS AND APPARATUS, METHODS, AND SYSTEMS FOR IMAGE PROCESSING |
摘要 |
<p>An adaptive filter according to one embodiment includes an N×N two-dimensional convolution, where N is an odd integer greater than one. Pixels of an image are filtered by moving the N×N kernel across the image. At each pixel location, the kernel coefficients are determined by the image pixels within the N×N region, such that the kernel coefficients may change from one pixel location to the next. Such a filter may be implemented to use a lookup table to approximate a floating-point operation.</p> |
