Oliver Kuckertz	a3d7811f24	Merge pull request #20725 from mologie:fix-dnn-tf-on-arm * dnn: fix unaligned memory access crash on armv7 The getTensorContent function would return a Mat pointing to some member of a Protobuf-encoded message. Protobuf does not make any alignment guarantees, which results in a crash on armv7 when loading models while bit 2 is set in /proc/cpu/alignment (or the relevant kernel feature for alignment compatibility is disabled). Any read attempt from the previously unaligned data member would send SIGBUS. As workaround, this commit makes an aligned copy via existing clone functionality in getTensorContent. The unsafe copy=false option is removed. Unfortunately, a rather crude hack in PReLUSubgraph in fact writes(!) to the Protobuf message. We limit ourselves to fixing the alignment issues in this commit, and add getTensorContentRefUnaligned to cover the write case with a safe memcpy. A FIXME marks the issue. * dnn: reduce amount of .clone() calls * dnn: update FIXME comment Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>	3 years ago

easonycwang	91ff45fbde	Tile: This submission is used to improve the performance of the inpaint algorithm for 3 channels images(RGB or BGR). Reason: The original algorithm implementation did not consider the cache hits. The loop of channels is outside the core loop, so the perfmance is not very good. Moving the channel loop inside the core loop can significantly improve cache hits, thereby improving performance. Performance: 360P, about >= 30% improvement iphone8P: 5.52ms -> 3.75ms iphone6s: 14.04ms -> 9.15ms	3 years ago
