Paul Murphy	1c4a64f0a1	Merge pull request #16138 from pmur:reg_16137 * imgproc: Prevent 1B overrun of 8C3 SIMD optimization The fourth value read via v_load_q is essentially ignored, but can cause trouble if it happens to cross page boundaries. The final few iterations may attempt to read the most extreme elements of S, which will read 1B beyond the array in most aligment cases. Dynamically compute the stop. This could be hoised from the loop, but will require a more extensive change. Likewise, cleanup the iteration increment statements to make it more obvious they do channel count (3) elements per pass. This should resolve #16137 * imgproc(resize): extra check	5 years ago

Paul Murphy	a011035ed6	Merge pull request #15257 from pmur:resize * resize: HResizeLinear reduce duplicate work There appears to be a 2x unroll of the HResizeLinear against k, however the k value is only incremented by 1 during the unroll. This results in k - 1 duplicate passes when k > 1. Likewise, the final pass may not respect the work done by the vector loop. Start it with the offset returned by the vector op if implemented. Note, no vector ops are implemented today. The performance is most noticable on a linear downscale. A set of performance tests are added to characterize this. The performance improvement is 10-50% depending on the scaling. * imgproc: vectorize HResizeLinear Performance is mostly gated by the gather operations for x inputs. Likewise, provide a 2x unroll against k, this reduces the number of alpha gathers by 1/2 for larger k. While not a 4x improvement, it still performs substantially better under P9 for a 1.4x improvement. P8 baseline is 1.05-1.10x due to reduced VSX instruction set. For float types, this results in a more modest 1.2x improvement. * Update U8 processing for non-bitexact linear resize * core: hal: vsx: improve v_load_expand_q With a little help, we can do this quickly without gprs on all VSX enabled targets. * resize: Fix cn == 3 step per feedback Per feedback, ensure we don't overrun. This was caught via the failure observed in Test_TensorFlow.inception_accuracy.	5 years ago
