Document Type and Number:
Japanese Patent JP2022094321
Kind Code:
A
Abstract:
To provide a method, system, and computer program which performs difference-guided video analysis.SOLUTION: The method includes obtaining a set of frames having a second resolution from a video having a first resolution. The first resolution is higher than the second resolution. The set of frames includes a first frame and a second frame. The method further includes generating a difference feature map, obtaining a third frame having the first resolution, detecting a first location of a first object in the third frame on the basis of the difference feature map, and acquiring a first cropped area from the third frame. The first cropped area is smaller than a third frame area. The method further includes generating a spatial attention layer on the basis of a feature map and the difference feature map and detecting the first object in the first cropped area by the spatial attention layer.SELECTED DRAWING: Figure 4
