Abstract:
1. A method for synthesizing moving images, comprising the steps of: sampling two consecutive frames from a moving image; providing a reference patch having at least one rectangular region therein, in one of the two frames, which is designated as a reference frame; providing a second patch, which is the same as the reference patch, in the other of the two frames; moving and/or deforming the second patch in the other of the two frames so that an image within the second patch matches that within the reference image; estimating correspondent relationships among pixels within the second patch of the other frame and pixels within the reference patch of the reference frame, based on the second patch after the movement and/or deformation thereof and the reference patch; obtaining a coordinate converted frame, by coordinate converting the image within the second patch into a coordinate space of the reference frame, based on the correspondent relationships; calculating a correlative value, which represents a degree of correlation between the images within the reference patch of the reference frame and the coordinate converted frame; varying the number of said at least one rectangular regions within the reference patch and the second patch in a stepwise manner, estimating the correspondent relationships, obtaining the coordinate converted frames, and calculating the correlative values for each number of said at least one rectangular regions, thereby obtaining a plurality of correlative values corresponding to the number of rectangular regions within the reference patch and the second patch; comparing the degrees of correlation for each number of said at least one rectangular regions, based on the plurality of the correlative values; and generating a synthesized frame having a higher resolution than either of the two frames, by administering interpolation calculations on the images within the second patch and the reference patch, based on the correspondent relationships, which were estimated among the pixels of the reference patch and the second patch having the number of said at least one rectangular regions therein that yielded the highest degree of correlation.
