2017-06-20 11:47:51 -0600 | asked a question | findcontour points order Hi, I'm using this function: Debugging my application I noticed that for any contour detected, the first point, contour[0], always is the topmost point, with the lowest y value. Is that really true? I didn't find any reference in the documentation about the point order. Is this a reliable way to find the topmost point of a contour? |
2016-10-18 11:22:49 -0600 | asked a question | sequence of morphological operators Hi, I'm facing and old code review, and trying to optimize and better understand it. I have this function: Do I get the same result substituting the double erode function call with only one, doubling the structuring element? How to choose the structuring element shape? I've always tried to understand this part, but only found empirical solution on the web, (like this one). I'd like to have a logical approach to morphological operators. Any hints about this code will be appreciated. |

2016-09-27 03:47:42 -0600 | asked a question | handle waitkey in multi-thread application I have a multi-threading application written in C++ with Qt5.7 and OpenNI. It has a main thread that starts a second thread which capture frame from a .oni recording file (asus xtion pro live) does some processing and through the Qt signal-slot mechanism pass the frame to the main thread, which display it using imshow(). What I want to do is to implement a pause key, so pressing for example 'p' the processing pause. I am thinking of something like this: In this way it doesn't work, I think that's because the frame is displayed by another thread (the main one), the waitKey() here simply blocks the entire process, but if I put it in the main thread, just after imshow() in this way: waitkey seems to be ignored (image displaying works fine).. any idea? |
