2015-06-20 03:54:08 -0600 | asked a question | Optimize matrix row copying in OpenCV I have a [32678 x 10] matrix (w2c) and I want to copy 24700 rows of it to another matrix(out). I have the index of the rows to be copied in a vector(index). For doing this in matlab I do: It takes approximately 0.002622 seconds. In OpenCV: It takes approximately 0.015121 seconds. As you can see Matlab is 6 times faster. How can I make the OpenCV code efficient? |
2015-06-15 03:02:02 -0600 | asked a question | Is there a way to prevent rounding in opencv matrix divison I have an integer matrix and I want to perform an integer division on it. But opencv always rounds the result. I know I can divide each element manually but I want to know is there a better way for this or not? |
