Title: TARGET DETECTION METHOD AND DEVICE
Abstract:
A target detection method and device, relating to the technical field of video processing. The method comprises: obtaining an image sequence to be detected from a video to be detected according to a video timing-based image sequence determination algorithm (S101); extracting a first CNN feature of the image sequence to be detected based on a pre-trained CNN model, and performing feature fusion on the first CNN feature according to a second CNN feature to obtain a first fusion CNN feature of the image sequence to be detected (S102); inputting the first fusion CNN feature to a first-order classifier, and obtaining a first alternative target region in the image sequence to be detected from the output result of the first-order classifier (S103); determining a first input region of a second-order classifier according to the first alternative target region (S104); obtaining a third CNN feature of the first input region according to the first fusion CNN feature (S105); and inputting the third CNN feature to the second-order classifier, and obtaining the target detection result for the image sequence to be detected according to the output result of the second-order classifier (S106).
