Problems solved by technology

Among the three typical lens types, the field of view of medium shot and close-up is not very wide. For these two types of lenses, the audience can basically see and understand the playback content on mobile devices, although the playback effect is relatively high. Clear TV has declined , but it can still meet the requirements of clarity and completeness, so this method does not treat these two types of
For long shots, due to the wide field of view and shooting distance, playing on mobile devices will bring great inconvenience to viewing. For this kind of shot, we determine the area of ​​interest and only play the area of ​​interest on mobile devices. content

Embodiment Construction

[0099] An implementation example of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0100] The present invention realizes clear and real-time broadcasting of football matches in mobile devices in a low-resolution environment, and the program frame diagram is as follows figure 1 shown. It is programmed and implemented on a PC test platform with a CPU of 3.0GHz and a memory of 1024M. Figure 3-10 Some results of the processing are given.

[0101] The invention fully excavates the characteristics of the football game itself, and realizes clearly playing the football game in real time on the mobile device. Divide shots into three typical types: long shots, medium shots, and close-ups. Different processing measures are taken for different types of lenses: the field of view of the middle ground and close-up is not wide, and users can watch it clearly even in the low-resolution environment of mobile devices. In view of this feat...

Abstract

The invention relates to a method of intelligently displaying a football video used for mobile devices. The method comprises the following steps: building a model for a football ground to obtain the basic statistic information of the football ground; separating the ground from other objects; realizing the shot clustering on the basis of the ground model; and finally extracting dynamically and displaying the region of interest in a football game. The method fully utilizes a quantity of characteristics of the football game, and realizes the real-time display of football game video intelligently in a mobile device. The method is region-based, and has the advantages of simple structure, high efficiency and practicability and high real-time performance.

Description

technical field [0001] The invention relates to a method for playing football game video in real time for mobile devices. This method adopts a completely region-based algorithm, which can intelligently play football videos in real time in the low-resolution environment of ordinary mobile devices. Almost the same visual effect on high-resolution display devices. Background technique [0002] With the rapid development of multimedia technology, it has become a reality to broadcast TV programs in real time on mobile devices; with the improvement of people's living standards, more and more people show their love for sports and watch sports games on mobile devices. Also become more and more popular thereupon, watch the real-time broadcast of football match in the mobile device and especially attract people's attention. However, due to the limitation of the mobile device itself, such as the very limited screen size, it will bring great inconvenience to the user when watching the...
