Abstract

The invention provides an image type determination method and device, equipment and a storage medium. The method comprises the following steps: obtaining a current image; determining a position of the current image in a current coding image group; and determining an image type of the current image according to the position of the current image in the current coding image group. According to the embodiment of the invention, the image type of the current image is determined according to the position of the current image in the current coding image group; for example, when the position of the current image in the current coding image group is not the last image, whether the current image is a scene switching image or not, the image type of the current image is determined to be a non-I frame, so that the current coding image group is prevented from being cut off, the problem that a compression ratio is reduced due to the fact that a complete prediction structure is damaged is avoided, and the video compression efficiency is further improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a method, device, device, and storage medium for determining an image type. Background technique [0002] Digital video technology can be incorporated into a variety of video devices, such as digital televisions, smartphones, computers, e-readers, or video players, among others. With the development of video technology, the amount of data included in video data is relatively large. In order to facilitate the transmission of video data, video devices implement video compression technology to enable more effective transmission or storage of video data. [0003] At present, redundant information in video data is reduced or eliminated by inter-frame prediction or intra-frame prediction, so as to realize video data compression. Generally, images whose image type is P frame or B frame adopt inter-frame prediction, and images whose image type i...
