2014-11-25 03:11:46 -0600 | commented answer | How to convert 2d into 3D image I tried H1 and H2 instead of Q. But it shows the same error. |
2014-11-11 04:00:58 -0600 | asked a question | How to reconstruct 3D image Now am doing conversion of 2D image to 3D image. So for that I am using the function reprojectImageTo3D(imgDisparity8U, xyz, Q, true); But I got an error like this. Assertion failed (Q.size() == Size(4,4)) in reprojectImageTo3D, file /home/arya/stuff/opencv/opencv-2.4.7/modules/calib3d/src/calibration.cpp, line 2823 Could you tell me what is xyz and Q? And what are the values given to these variables? |
2014-11-11 02:44:48 -0600 | asked a question | How to convert 2d into 3D image Now I am doing conversion of 2D images to 3D images. For that am using following steps. (1). Input 2 images. (2). Detect keypoints using SIFT. (3). Extract Descriptors. (4). Compare and match descriptors. (5). find fundamental mat (findFundamentalMat()) from these pairs. (6). stereoRectifyUncalibrated(). (7). reprojectImageTo3D(). Now I want to know that what is this xyz and Q in reprojectImageTo3D? And what are the values given to xyz and to Q? reprojectImageTo3D(imgDisparity8U, xyz, Q, true); Because I got an error like this: OpenCV Error: Assertion failed (Q.size() == Size(4,4)) in reprojectImageTo3D, file /home/arya/stuff/opencv/opencv-2.4.7/modules/calib3d/src/calibration.cpp, line 2823 |
2014-11-06 05:19:49 -0600 | commented answer | Multiple SVM for Face Recognition ok.Thank you for your reply.. |
2014-11-05 22:26:01 -0600 | commented answer | Multiple SVM for Face Recognition I already set this minimum face size and maximum face size. double min_face_size=30; double max_face_size=400; these values are used at the time of detection. But I don't know where I set minimum face size at the time of recognition. |
2014-11-05 03:34:11 -0600 | commented answer | Multiple SVM for Face Recognition So what I do to overcome this? Do you have any suggestions or solution? |
2014-11-04 22:15:24 -0600 | commented answer | Multiple SVM for Face Recognition But in my case when a person nearer to camera it identify as known but when distance increases the same person identify as unknown. Could you tell me why? |
