METHOD AND SYSTEM FOR CREATING AN INTERPOLATED IMAGE |
摘要 |
The invention relates to a method for creating an interpolated image between a previous image and a current image in a video stream. The invention also relates to an image processing system for creating an interpolated image between a previous image and a current image in a video stream. The invention is based on the following principle: a motion estimator generates at least two vector fields, one at a temporal position smaller then 1A, and another at a temporal position greater than 1A. Then occlusion detection is done to detect covering and uncovering areas. A first vector is fetched from the first vector field and a second vector is fetched from the second vector field. If there is covering, the up-conversion vector is the second vector; if there is uncovering, the up-conversion vector is the first vector; if there is no uncovering-covering, the up-conversion may be either the first vector or the second vector. In this way, the up-conversion vector points at the correct original segment values in the previous image and the current image. |
