摘要:
To enable obtainment of a composite image including a movement trajectory of a moving body, even from a moving image including a background. Sampling means samples frames from moving image data. First mask frame calculating means calculates mask frames including mask regions, which correspond to positions of the moving body on the frames. Second mask frame calculating means accumulates and binarizes the mask frames to calculate a reference mask frame. Region cutout means masks the frames by using the mask frames and the reference mask frame to cut out moving body regions, which correspond to a moving body, from the frames. Composing means overwrites moving body regions on one of the frames in chronological order to obtain a composite image, which includes the movement trajectory of the moving body.
摘要:
A single high resolution frame is obtained from a plurality of frames sampled from moving image data, regardless of movement of a subject included in the frames. Patches are provided in a plurality of frames including a reference frame and other frames. The patches are moved and/or deformed, and correspondent relationships are estimated for each frame. The other frames are coordinate converted based on the estimated correspondent relationships. Correlative values, which represent the degrees of correlation between the other frames and the reference frame, are calculated. The number of regions within the patches is changed, and the correlative values are calculated in the same manner. A synthesized frame is generated from the plurality of frames based on the correspondent relationship, which was estimated for the number of regions that yields the maximal correlation.
摘要:
To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrN and FrNnull1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrNnull1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrNnull1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient null(xnull, ynull) that makes the weight of the first interpolated frame FrH1 greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.
