2013-04-01 12:20:44 -0600 | answered a question | How can I imread just an ROI, not the whole image? You still need to read the entire binary file. But you can alter the part where OpenCV build a Mat object. You can just read your ROI from memory and create a smaller Mat object. |

2013-03-26 13:52:00 -0600 | asked a question | Access 32F Mat element by pointer Usually I do This is with a typical 8UC1 mat. Now, I want to store values that can range from -1500 to 1500. So I'm using a CV_32F mat. But I can't figure out how to store values inside. I always end up with corruption with incoherent values. Can someone help me? Edit, I mean 32F, not 32S, my mistake Thanks Seb |

I want to "stretch" it to go full screen without changing the camera resolution. OpenCV 2.4.4-beta Thanks Seb |
