Abstract
A detection method includes performing multiband filtering on a first area to obtain a plurality of band sub-images, the first area being an area in a first video frame, and performing multidirectional filtering on the plurality of band sub-images to obtain a plurality of direction sub-images. The method further includes acquiring a direction-band fused feature of the first area according to the plurality of direction sub-images, and inputting the direction-band fused feature into a detection model, and performing detection based on the direction-band fused feature using the detection model to detect whether the first area comprises an object.
