Problems solved by technology

[0009] 5. A method based on movie editing technology. This method uses movie editing technology to construct a high-level description of the video, and adopts a clustering method to similarly merge the shots after the video stream is divided to form a hierarchical organization of the shots, thereby realizing the video stream. Hierarchical browsing, but this method cannot reflect the timing relationship between shots
The above scheme is only a video-based scene detection scheme, and the accuracy of scene detection is poor

Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] From the perspective of human perception and knowledge learning, the semantics of vegetable disease control video scenes include the following features:

[0052] a) The content of the vegetable disease scene mainly includes two aspects: symptom description and disease control: a complete symptom description scene contains the symptoms of a part in a certain period of time; a complete disease control scene contains a certain step in the control measures . Therefore, these shots have a temporal correlation between sound and image.

[0053] b) The sound field in the vegetable disease scene includes two parts: commentary and transitional music. The sound in a commenta...

Abstract

The invention discloses a scene detection method of vegetable diseases and relates to the technical field of video analysis and detection. The method includes detecting a compressed video lens boundary point and a sound lens boundary point; marking a sound lens type as a voice type or a non-voice type after the sound lens boundary point is detected; and determining the change of the sound lens type and whether boundary points of a sound lens and a video lens are overlapped to obtain scene boundary detection results. According to the scene detection method of vegetable diseases, a semantic model of a vegetable disease scene serves as a judgment basis, not only the temporal continuity of the lens is considered, but also the relevance of the sound lens and the video lens is comprehensively considered during video scene detection, so that more accurate scene detection of vegetable diseases is achieved.

Description

technical field [0001] The invention relates to the technical field of video analysis and detection, in particular to a method for detecting vegetable disease scenes. Background technique [0002] Diseases are an important factor restricting the sustainable development of vegetable production in my country, and farmers' poor ability to accept information makes it difficult to diagnose vegetable diseases, and diseases cause serious losses to vegetable farmers. With the increasing number of video programs on vegetable disease prevention and control in the network, the video retrieval system can meet the urgency and real-time nature of farmers' knowledge of disease prevention and control, and at the same time improve the accuracy and interest of disease knowledge learning. [0003] A scene is a collection of shots expressing the same theme, which is the basis of video semantic analysis. The accuracy of scene detection is of great significance to the establishment of video data...
