2013-05-23 00:22:07 -0600 | answered a question | Camera calibration - getting bad rectified image Maybe the problem is the size of your images. The images (Chessboard Images) that you use to calculate calibration matrixes should have the same size with the images that you want to calibrate. |
2013-05-16 00:01:18 -0600 | commented question | OpenCV Machtching Feature Dear Notas, About Ordering: When the images are applied to the "stitching_detailed.cpp" as the arguments, the "matcher(features, pairwise_matches)" function try to find matches between all images and choose the best mached image for image number x. This procedure is done for all input images(compare it with all other input images to find the best match). I know that each input image in my algorithm has the best match with the image in next, I mean "image i" with "image i+1" and so on. So I want to skip comparing "image i" with all images except "image i+1". Because I know that they are in right order(The photos sequentially taken) the best matches for each image is the next one, so it is not neccessary to compare it with all inputs. It is exactly the problem that I have. |
2013-05-15 13:52:50 -0600 | commented question | OpenCV Machtching Feature Hi Notas, Maybe my question is not clear, but as you said, I need to compare the image just with the next image. I am confused right now. Would you please tell more in detail. |
2013-05-15 04:12:25 -0600 | asked a question | OpenCV Machtching Feature The function matcher(features, pairwise_matches) in OpenCV, suppose that the input images are not in order, so it tries to find the right order by processing the features and compare one image with others. It waste too much time for many input images like 20. The pairwise_matches is 400 for 20 input images. I want to insert the images in the right order to avoid comparing one with all others (just with the next one and reduce the pairwise_matches from 400 to 19 !!!). How can I implement it?!! Thanks in Advance |

2013-05-12 10:53:28 -0600 | commented answer | Problem with OpenCV calibration module Well, I dont have any idea about it right now, my friend. |
2013-05-08 02:12:42 -0600 | edited answer | Does the matching work in OpenCV 2.4.4? If you show the matches in one window, you can see that sometimes one feature point from first or second image is matched to more than one point in the other image. So, you will have more matches than 241. |
