Embodiment Construction
[0030] Combine below Figure 2 to Figure 6 , the present invention is described in further detail.
[0031] Such as figure 2 As shown, the present embodiment provides a video retrieval method based on fusion of multiple images, the method comprising the following steps S1 to S7:
[0032] S1. Decoding the database video and segmenting the video shots to obtain multiple video shots;
[0033] Specifically, the multiple video shots here refer to being divided into at least one video shot.
[0034] S2, performing key frame extraction on a single video shot, and performing local feature extraction on the key frame;
[0035] Specifically, at least one key frame is extracted from a single video shot, and feature extraction is performed on the key frame. The feature extraction here includes but is not limited to local feature extraction and global feature extraction. In this embodiment, local feature extraction will be performed on the key frame As a more preferred solution.
