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?

Thanks :) :)

2016-02-03 04:23:47 -0500 commented question Segmentation accuracy metric

How to create the ground-truth? I am planning to create manually. Is it a good decision?

Hi all, Is there any metric available for measuring the accuracy of video segmentation?

2016-01-25 03:50:14 -0500 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 -0500 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 -0500 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 -0500 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 -0500 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 -0500 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??
