The optical flow is an approximation for a 2D motion field of the velocity vectors of each pixel of an image, with every vector being a projection of the real 3D velocity of a corresponding surface point [4].
These color optical flow methods are restricted to brightness and color conservation over time. In this paper, a correlation-based color optical flow method is ...
The resulting color optical flow is compared to other representative multi-frame color methods and standard single- frame grayscale methods.
Abstract. Usually, optical flow computation is based on grayscale images and the brightness conservation assumption. Recently, some authors have ...
