resize算法求解 #4
Comments
我按照公式实现一版 resize,结果有大概30%左右的 pixel误差,整的人头有点大 |
应该是和opencv 3.1 c++的实现对齐的,有单元测试 |
哥 我读了你实现的双线性插值 resize 基本上和opencv的一模一样,我个人感觉opencv的可读性有点不太强,不太好定点打印出某个位置的值,如果你有相应的ref代码实现,那就非常完美了。我现在需要实现一版能和opencv完全对齐的向量化版本的算法,出师未捷啊,第一步就卡了 |
@Airbala 我就是按照opencv 3.1中的源码提取的,关闭掉simd, openmp等与加速相关的code,仅执行纯c++ code |

大佬请问一下你实现的 U8 的 resize 算法和 opencv 能做到 bit对齐吗?
