2017-02-14 12:23:51 -0600	asked a question	Space Variant Bluring Hi all, I want to apply gaussian blur with each pixel having separate sigma values. That is, i have a sigma matrix with size, same as the image. Any idea?
2016-07-01 00:16:57 -0600	asked a question	Orthorectifiacation in opencv Hi all, Is there any built in function for doing Orthorectification
2016-04-09 05:36:24 -0600	commented answer	Opencv Python codes Actually i need source code for cv2.calcopticalflowfarneback function.
2016-04-09 03:05:39 -0600	asked a question	Opencv Python codes Hi all, In which folder Opencv python stores the source files of built in functions. I am using OS X.
2016-03-27 02:32:36 -0600	asked a question	Shadows in video Hi all, I want to detect shadows in images. Any suggestions?
2016-02-03 22:06:51 -0600	asked a question	movement detection accuracy Hi all, I segmented the moving objects from video using optical flow. Now i want to measure the detection accuracy. Any help?
2016-02-03 05:04:34 -0600	commented question	Segmentation accuracy metric Thanks :) :)
2016-02-03 04:23:47 -0600	commented question	Segmentation accuracy metric How to create the ground-truth? I am planning to create manually. Is it a good decision?
2016-02-02 22:57:35 -0600	asked a question	Segmentation accuracy metric Hi all, Is there any metric available for measuring the accuracy of video segmentation?
2016-01-25 03:50:14 -0600	commented question	Mathematics behind contour detection algorithm I want to know that, whether contour detection is based on any edge detection algorithm or not.
2016-01-25 00:55:08 -0600	asked a question	Mathematics behind contour detection algorithm Hi all, what is the maths concept behind opencv contour detection algorithm?
2015-12-31 02:46:05 -0600	commented question	Median filter on optic flow vectors I am trying to track moving objects in video. Getting errors (showing non moving parts also as moving) when i follow the above mentioned procedure. So i thought of to remove those errors by filtering..
2015-12-31 02:31:09 -0600	commented question	Median filter on optic flow vectors I color coded the vectors based on the angle. Now i have the hsv frames. Can you tell me how to convert hsv to binary. I think InRange is not possible because there are many hue values.
2015-12-30 22:28:12 -0600	asked a question	Median filter on optic flow vectors Hi all, I want to track moving objects in video. I choose optical flow. I got the flow vectors using cv2.calcOpticalFlowFarneback. Then i classify moving objects based on the magnitude. But it is not showing accurate results. It is not segmenting the moving objects properly. Now i want to apply median filter on the flow vectors. Anybody can help me?

2015-12-28 21:54:07 -0600	asked a question	Cluster opencv vectors Hi all, I want to track moving objects in video. I choose optical flow for my code. I got the flow vectors using cv2.calcOpticalFlowFarneback function. Now i want to draw boundary along different objects. How can i cluster the flow vectors??
2015-12-10 00:33:52 -0600	commented answer	createOptFlow_DeepFlow function in python opencv? How it is possible in opencv 2.4.10.1?? How can i build using opencv_contrib? I am new to this, please help.
2015-12-10 00:03:24 -0600	asked a question	createOptFlow_DeepFlow function in python opencv? Is there a function like createOptFlow_DeepFlow in opencv python for optical flow calculation?
2015-04-09 01:01:25 -0600	asked a question	Details about the method used in createLBPHFaceRecognizer.train?? Hi all, which training method is used in createLBPHFaceRecognizer.train?
