2013-11-20 11:19:50 -0600 | asked a question | opencv transformation perspective Hello, I get a picture taken in perspective and wishes to restore its original form. For this I use the code snippet below: My original image is in Dossard[j] . img For the sake of simplicity, and because I did not understand why my resulting image corresponded to nothing , I put the same coordinate values for the 2 images ( dstTri [0] = srcTri x [0] x . . ; ... ) . I thought in this case that the image given by cvWarpAffine would be exactly the original. But this is not the case , and this is just to ask me some help . The original image is a rectangle 54 pixels wide by 56 pixels high) containing 4 figures photographed at a slight angle The resulting image is a cream white uniform image (note : I notice that the color corresponds to the first pixel of the original image Random . ? ) Is anyone know why I have this result and what am I doing wrong ? Thank you in advance for your help. |

2013-11-05 13:34:18 -0600 | asked a question | rectangle coordinates x,y square.c Dear, I am not a very good software maker, but I have a need to find some rectangles in a picture ,transform them into a rectangle if deformed, and extract them into onthers images. For that, I use the example square.c from the opencv example, and :
But the result of this function is complex and I don't knwo where I can find the coordinates of my rectangles. Does anybody can help me ? Thanks a lot. |
