Continuous adjustable 3Deeps Filter Spectacles for optimized 3Deeps stereoscopic viewing, control method and means therefor, and system and method of generating and displaying a modified video

A source video comprising 2D image frames is acquired, and an image frame including two or more motion vectors describing motion in the image frame is obtained, wherein each of the motion vectors is associated with a region of the image frame. A parameter is calculated for the following: (a) a lateral speed of the image frame, using the motion vectors, and (b) a direction of motion of the image frame, using the more motion vectors. A deformation value is generated using an algorithm that uses both of the parameters, and is applied to the image frame to identify a modified image frame. The modified image frame is blended with a bridge frame that is a non-solid color and different from the modified image frame, to generate a blended frame. The direction of motion and velocity of motion parameters are calculated from the motion vectors.
