WebTherefore, an affine transformation matrix was built to solve the background model between the adjacent frames. Because the optical flow estimate of the image pixel depicts a certain error, the optical flow estimate of the pixel point has a higher estimation accuracy at the image brightness change area and the image gradient change area. WebApr 15, 2024 · This is indeed as expected due to the strong diffusion effect of the affine transform and MDS matrix. On Three Variables. Since the algebraic degree will reach 126 after 9 steps when there are 2 variables, we can argue that the algebraic degree will be much larger than 128 after 9 or 10 steps when considering 3 variables.
