20140363053 | METHOD AND DEVICE FOR GENERATING A MOTION FIELD FOR A VIDEO SEQUENCE - A method for generating a motion field between a current frame and a reference frame belonging to a video sequence from an input set of elementary motion fields is disclosed. The method comprises performed for each pixel belonging to said current frame: determining a plurality of candidate motion vectors between the current frame and the reference frame wherein each candidate motion vector is the result of the sum of a first motion vector between the current frame and an intermediary frame belonging to the video sequence and of a second motion vector between the intermediary frame and the reference frame; and selecting a motion vector among candidate motion vectors. The method is remarkable in that elementary motion fields are obtained with different time intervals between pairs of frames and in that the first motion vector belongs to the input set of elementary motion fields and the second motion vector belongs to a set of previously selected motion vectors for other current frames of the video sequence. | 12-11-2014 |
20150015792 | FILTERING A DISPLACEMENT FIELD BETWEEN VIDEO FRAMES - The invention relates to a method for filtering a displacement field between a first image and a second image, a displacement field comprising for each pixel of the first (reference) image a displacement vector to the second image (current). The method comprises a first step of spatio-temporal filtering wherein a weighted sum of neighboring displacement vectors produces, for each pixel of the first image, a filtered displacement vector. The filtering step is remarkable in that a weight in the weighted sum is a trajectory weight, that is a trajectory weight is representative of a trajectory similarity. According to an advantageous characteristic, a trajectory associated to a pixel of the first image comprises a plurality of displacement vectors from the pixel to a plurality of images. According to another advantageous characteristic, a trajectory weight comprises a distance between a trajectory from the pixel and a trajectory from a neighboring pixel. The method also relates to a graphics processing unit and to computer-readable medium for implementing the weight filtering method. | 01-15-2015 |
