。加速策略概述：算法本身优化裁剪，opencl加速，fastcv（高通手机）,neon（arm），dsp指令，open omp，硬件加速单元 。open omp打开编译器openmp支持，增加代码即可； #pragma omp parallel for xx codexxx find_package(OpenMP) if (OPENMP_FOUND) MESSAGE("OPENMP FOUND") set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}") set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}") elseif () MESSAGE("CAN NOT FOUND OPENMP") endif()
