Determination of control point sets for motion description based on motion interpolation accuracy constraints
A region-based control point determination strategy for multivector motion description is proposed, which is strictly based on region contour information and the application of motion interpolation accuracy constraints to drive the location procedure. This approach gives two main advantages while keeping a reasonable computational cost: operation on arbitrary shaped regions of the image and the complete elimination of the transmission of any information related to the number and position of the control points.
