Abstract: A method, system, and computer program product, include recording high-frequency wave data of local arid adjacent fault curves of a power grid to compare the high-frequency wave data with historical fault data to detect an actual fault region in the power grid, the power grid having a plurality of sensors distributed in the power grid, each sensor being upstream of one adjacent sensor and downstream of an other adjacent sensor.

Abstract: A method, system, and computer program product, include obtaining a dataset related to a power grid collected by a plurality of sensors distributed in the power grid, identifying a region as a candidate fault region based on first data in the dataset, the first data being collected by a first sensor from among the plurality of sensors that is located in the region, and verifying the candidate fault region based on second data in the dataset, the second data being collected by a second sensor from among the plurality of sensors that is adjacent to the first sensor.

Abstract: A method includes obtaining from a video having a first resolution, a set of frames having a second resolution with the first resolution being higher than the second resolution and the set of frames includes a first frame and a second frame from which difference feature map is generated. A third frame having the first resolution and a third frame area is then obtained from the video and a first location of an object is detected in the third frame using the difference feature map. A first area smaller than the third is then cropped from the third frame and a feature map generated of this first area. A spatial attention area is then generated based on the difference feature map and the first feature map and used to detect the first object in the first cropped area.
