運行速度問題 #43

SIMD选项呢 |
選擇了SSE2,但是有一條warning: |
有个MIPP test可以知道开了没有。选AVX呢 |
可能是opencv比较老的版本不支持这个?试试把step1()改成cols()*channels() |
我看都是跟opencv相关,可能opencv需要也用AVX编译? |
重新編譯了好多次opencv都沒有效果,最後偶然找到了原因,我的CPU不支持AVX2!換了機器之後這個問題解決了! |
哈哈,居然是这样。response map可以这样进一步加速,我估计最后能到halcon 20ms的程度,因为最好情况就是只从主存读写一遍。 |
您好,vs2019的SSE2在哪儿启动呢? |
你好,你做完加速了没?现在能到多少时间? |
你是用什么环境编译的?最后加速效果怎么样了?我也遇到了同样的问题,我100万像素照片,136ms,慢,要加速,使用的是vs2019环境。 |
您好,我有設置O2,也有開啟openmp,100萬像素的圖像匹配速度在一百毫秒以上,請問問題出在哪裡呢,謝謝。
