A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: acquiring image information from a bitstream, the image information including a picture header related to a current picture, and the current picture including a plurality of slices; parsing, from the picture header, a first flag indicating whether information necessary for an inter prediction operation is in the picture header and/or a second flag indicating whether information necessary for an intra prediction operation is in the picture header; parsing, from the picture header, the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation on the basis of the first flag and/or the second flag; and generating prediction samples by performing intra prediction and/or inter prediction for a current block in the current picture on the basis of the information necessary for the inter prediction operation and/or the information necessary for the intra prediction operation.

High level syntax signaling method and device for image/video coding

The invention discloses a remaining and stolen moving object detection method and equipment and a storage medium. The method comprises the following steps: acquiring a scene image, and extracting features of the scene image by adopting a trained network; acquiring characteristics of a background image corresponding to the scene image, and calculating a characteristic difference degree between thebackground image and the scene image according to the characteristics of the scene image and the characteristics of the background image; and if the feature difference degree is judged to be higher than the comparison threshold, determining that the scene image is a left-behind or stolen image. The remaining and stolen detection method is simple and convenient, the calculation complexity of remaining or stolen detection is reduced, the scene image can be detected in real time, a foreground object does not need to be extracted, the operand is reduced, and the operation efficiency is improved.
