Hi all

Can any one help me how to model the variation of each pixel in grayscale image using its mean and std

as there is one function in matlab normpdf.

y=normpdf(img,mean(img(:),std(img(:))));

Any help is appreciated..

Thanks.

how can I update the threshold equations.

because if I compute the mean it is just row vector i want to compute the mean of each pixel in bgframe.

As I have declared the first frame for background modelling and rest of other are the current input frames for object detection.
