hello
when i use the VLIB2.0 to realize mixture of gaussion in DM6437,I can run through the project,but i cant get the foreground region of my image.when i view the memory of the outputImage buffer ,i only can see zero.And when i view the image of the fgMask buffer through the tool of Gragh,i can see it is a offset of my original image.The specific procedures is as follow.Is it a problem of my original image? or other problems? Any insight would be much appreciated! Thanks!
