| 2016-03-09 04:28:49 -0600 | answered a question | How can i cluster moving objects in a video ? http://www.wisdom.weizmann.ac.il/~ira... This paper is a bit complicated. but worth trying and implementing. you are working with a problem where u need to distinguish between independent motion detection and motion of the camera which is the dominant motion. For your information this is a research topic. And not easy to get a straight result |
| 2016-03-09 02:51:13 -0600 | asked a question | Is Grid a dense optical flow I am running optical flow on a grid of fixed points(with Lucas Kanade) rather than running on every point (not with farnback). Is this still a dense optical flow. Is it the idea way to do dense. we are thinking of doing it this way to reduce the computation time. Can I get some better advise. We are looking to get the motion data from the video. Any dominant motion in the scene, we want to capture, with low computation time with moderate accuracy. Thanks |

| 2015-10-05 04:54:42 -0600 | commented question | Identifying the left and right camera from 2 images captured at different time intervals yes you are right ... Yes I did try rectifying the images. but after that how would I know which is left and which is right !! |
| 2015-10-01 07:20:16 -0600 | commented question | Identifying the left and right camera from 2 images captured at different time intervals well that alone will not give me a complete solution. I would like to know atleast if it is possible to solve this problem statement ? or I am hitting on a wall with less information and more assumptions ?? |

| 2015-10-01 03:45:52 -0600 | asked a question | Identifying the left and right camera from 2 images captured at different time intervals I have been give with 2 camera images which sees the same scene but captured with different time. I will have to find out which image is being captured by which camera (Which camera is left and which camera is right). Image can be given in either order. I tried 2 approaches 1) Finding the keypoints and match (Used sift) homography and draw the epipolar lines and then find the intersection of the lines to find the epipoles. 2) Create a mosaic and find out which is left and which is right. Both these methods are not working in all the cases. Case 1: when the fixation point is at infinity Case 2: when the fixation point is closer (in foreground) I looked in to other options like Bundle Adjustment but I am not clear how to do it and where to start. Any help would be appreciated. Thank you. Example images :
