Hi all,
One of the CImg examples given regards image registration/morphing of David's face between two viewpoints. Looking at the code, a motion vector field ("u") is calculated and used to estimate the motion between the two frames. *
*
The optflow() function uses the get_norm_pointwise function - this seems to be the function to use when calculating how much estimated x,y,z motion there has been between frames. I am just wondering what the 1,2,-1 argument values of this function means?*
*
By the way, is my interpretation correct? Is get_norm_pointwise "the" function to use in this regard?
How do I go about finding the translated x, y values of a pixel? Ultimately, I know that getting the norm of the pixel value will give this, but how do I determine the x and y values?
