Embodiment Construction

[0026] The video subtitle content analysis system provides two methods: video subtitle analysis based on task scheduling server and local video file subtitle analysis.

[0027] 1. Video subtitle analysis based on task scheduling server

[0028] The video subtitle analysis based on the task scheduling server is triggered by the upper layer video analysis scheduling server to trigger the analysis task. After the system successfully communicates with the upper-layer video analysis and scheduling server, the server issues task instructions for manipulation. After receiving the analysis task instruction, the system starts the entire analysis task process, including video stream decoding, complex background removal, subtitle frame automatic detection, subtitle area automatic positioning and extraction, subtitle area character adaptive segmentation, OCR recognition, subtitle feature metadata XML generation and Notify the upper scheduling server of the end of the task and upload the ...

Description

technical field [0001] The invention relates to a video analysis system based on content, in particular to a video analysis system based on subtitle content. Background technique [0002] In the traditional text-based video retrieval, the video is annotated with text first, and then the video is retrieved with a text-based database management system. However, with the rapid increase in the number of digital images and video data, if the traditional database technology that has been successfully applied in the field of text data is transferred to the multimedia fields such as images and videos, the result will inevitably be inefficient or even ineffective. of. [0003] Content-based visual information retrieval uses the process of processing, analyzing and understanding visual media from low-level to high-level to obtain its content and retrieve it according to the content. It involves effective query, indexing, browsing, searching and extraction of visual information in im...
