| // i) The largest block size is 128x128, so the distance from the block |
| // center to an edge is <= 64 pixels. And the warp filter has 64 |
| // sub-pixel kernels. |
| // Thus any change of less than about 1/(2^12) pixels/pixel |
| // will not change anything. |
| // |
| // ii) The precision of the {alpha, beta, gamma, delta} parameters |
| // which are used in the warp filter is only 10 fractional bits |
| // (see the use of WARP_PARAM_REDUCE_BITS in av1_get_shear_params()) |
| // |
| // Thus any changes of < 1/(2^10) pixels/pixel will generate the |
| // exact same prediction. |
| // |
| // iii) The maximum shift allowed by the warp filter is on the |
| // order of 1/4 to 1/8 of a pixel per pixel, and we probably |
| // want to be able to span this range in a reasonable number |
| // of steps. |
| // eg. if we allow shifts of up to +/- 1/8 pixel/pixel, split |
| // into 8 steps, then our refinement size is 1/64 pixel/pixel |
