The present application relates to the technical field of video processing. Disclosed are a video clip positioning method and apparatus, a computer device, and a storage medium. According to the present application, a plurality of video frame characteristics of a target video, and the text characteristics of a target text are obtained by a video recognition model, one candidate clip matching the target text is determined, the candidate clip is finely divided on the basis of the matching degree between a video frame in the candidate clip and the target text to obtain a plurality of subclips, and a subclip having the highest matching degree with the target text is used as a target video clip. The approach of performing characteristics matching for multiple times, dividing the obtained candidate clip again so as to determine the target video clip makes it unnecessary for the video recognition model to learn the boundary characteristics of the target video clip and accurately annotate a sample video during model training, shortens the training period of the video recognition model, and avoids the problem of low accuracy of the model output result caused by the inaccurate sample video annotation.

Abstract

The present application relates to the technical field of image processing, and disclosed are a character recognition method and apparatus, a computer device and a storage medium. The technical solutions of the embodiments of the present application may be used to extract a target number of characters from an image to be recognized. By means of extracting an image feature of an image, the image feature comprising a plurality of image feature vectors, an attention mechanism is employed; and according to the plurality of image feature vectors, attention weight values corresponding to the target number of characters are calculated and outputted by means of parallel calculation. One attention weight value may represent the degree of importance of the plurality of image feature vectors for a character corresponding to an attention weight value. As a result, during the process of character recognition, by means of the foregoing attention mechanism-based recognition, characters of any shape may be effectively recognized by means of a simple process, thereby avoiding the process of cyclic calculation and greatly improving the calculation efficiency.
