My Friend How To Make This Program?

[Shaunakde]

Hi,

I am trying to use color based object detection too (Using Aforge libraries on c#). I am applying the HSL filter, but I notice that HSL calculations take way more time (and make my video stutter)

Do you notice this problem in OpenCV? Or do you avoid the HSL colorspace altogether?

[amizorach]

@Shaunakde Hi

I have not used the HSL algorithm as I needed better results

I used a combination of spectrum changes.

I have however experimented with the HSL in open CV and found it to work fast enough

@amizorach

Hi, Thanks for the reply. I will give OpenCV's c# wrappers a try.

I did not quite understand what you meant by "combination of spectrum changes". I am very interested in finding out more about your technique. Could you please direct me to relevant documentation/papers? Or perhaps outline the method (if its Ok with you)

[amizorach]

I will try to elaborate when I have some more time

But the main idea was to simply find the point of interest (according to colour) and then try to approximate where it might be next (movement). this allows me to scale down the entire frame into an expected block and run a more detailed search with a smaller variant on the smaller rectangle.

@Shaunakde I also used a feature I was developing to segment the picture and I was hoping to be able to parse the moving objects so I can follow them even if they are a bit covered (a hand moving in-front of the another one) although I was able to get a pretty good response when using the colour markers I struggled when it came to regular hands and differentiating them from the face.

@amizorach Thanks for the reply. I have somewhat of a clear idea now and am beginning to understand the algorithm. Thank you! :)
