Background Subtraction Tracking : 3 - Pygame OpenCV

[FenestronX]

good job! would u give some tips about that

i am trying to track an object with color based thresholding algrithm

but there is some noise at the back ground..

can i use this algorithm to obtain an image witout noise?

i try cv.Sub() function but it returns error as follow

cv.Sub(thresholded_img,thresho­lded_img,thresholded_img,0)

TypeError: CvArr argument 'mask' must be IplImage, CvMat or CvMatND

thanks in advance :)

@FenestronX Thank you, This is not a color track example, you can see one here, watch?v=qV7CHkbQW3Q , tracking red =] ... For colocar tracking you`ll use cv.InRangeS.

There is Robust Background Subtraction algorithm that learn backgrounds and produce less noise, this is not the case ...

You`ll use cv.AbsDiff for to create the diference ... the subtraction ....

Hope it will help you .... Thank you
