Abstract
An apparatus for detecting motion at a temporal intermediate position between a previous image and a next image has optimizing means (1) for optimizing a criterion function for candidate vectors, whereby the criterion function depends on data from both the previous and the next image. The motion is detected at the temporal intermediate position in non-covering and in non-uncovering areas. The apparatus according to the invention has means for detecting covering and uncovering areas (2) and has its optimizing means being arranged to carry out the optimizing at the temporal position of the next image in covering areas and at the temporal position of the previous image in uncovering areas.
Claims25
A method for detecting motion at a temporal intermediate position between previous and next images, in which a criterion function for candidate vectors is optimized, said function depending on data from both previous and next images and in which the optimizing is carried out at the temporal intermediate position in non-covering and non-uncovering areas, characterized in that the optimizing is carried out at the temporal position of the next image in covering areas and at the temporal position of the previous image in uncovering areas.
An apparatus for detecting motion at a temporal intermediate position between previous and next images, comprising means for optimizing a criterion function for candidate vectors, said function depending on data from both previous and next images in which the optimizing is carried out at the temporal intermediate position in non-covering and non-uncovering areas, characterized in that said apparatus further comprises means for detecting covering or uncovering areas, wherein the optimizing is carried out at the temporal position of the next image in covering areas and at the temporal position of the previous image in uncovering areas.
