Embodiment Construction

[0050] The reflection of human eyes on information belongs to the research category of cognitive psychology. Cognitive psychology believes that people have visual working memory (Visual Working Memory), which refers to the short-term storage of non-verbal visual information, which is the temporary storage of visual information before further processing. The research on visual working memory mainly focuses on the storage mode and capacity of visual object information in working memory. The researchers found through experiments that due to the limited visual capacity, people can only track 4-5 target items and store the movement direction information of about 3 objects. Therefore, the present invention combines this research result and proposes a method and system for generating a video outline, which can make the video of the video outline as short as possible and allow observers to observe comfortably.

[0051] Similar to the prior art, the present invention is divided into f...

Abstract

The invention provides a method for producing a video outline and the method comprises the steps as follows: carrying out moving object detection to a video frame to obtain a moving object and a background; tracking the moving object and producing the track of the moving object; calculating the video outline on the basis of the knowledge of cognitive psychology and re-arranging the track of the moving object accordingly; combining the background and the re-arranged track of the moving object to produce the video outline. The method of the invention avoids the disorder of the moving object in the output video outline so as to be suitable for observation for human eyes and provide convenience for customers to observe effective information in an original video as well as further avoids the collision of the moving object when being re-arranged and maintains the original timing sequence consistency of the object as far as possible.

Description

technical field [0001] The invention relates to the technical field of image processing, and further relates to the field of video summarization. Background technique [0002] Video summarization is a concept derived from text summarization. Text summarization is a brief summary of an article or a paragraph of text. Therefore, video summarization is to process a long video content to obtain a brief summary. It is to analyze the structure and content of the video in an automatic or semi-automatic way, extract the meaningful parts of the original video, and then combine them in a certain way to form a brief summary that can fully express the video content. This summary can be represented in the form of text, or some still pictures or a video shorter than the original video, and most of the video summarization technologies are represented by the latter. [0003] Traditional video summary technology can be divided into two categories according to the different forms of summary:...
