Embodiment Construction

[0034] The specific implementation of the video compression method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 A flow chart of a video compression method of an embodiment is shown, which mainly includes the following steps:

[0036] Step S101, acquiring a background image from the continuous pictures taken.

[0037] Specifically, by extracting the same or similar background image parts in the consecutive pictures, as shown in 2, in order to facilitate the understanding of the technical solution of the present invention, three consecutive pictures containing moving objects taken in a scene are selected below P1, P2, and P3 are used for illustration. Usually, when compressing into high-definition video according to the existing method, these three pictures are played one by one during the broadcasting process. In fact, the background image B, such as image 3 As shown, in the process of playing the...

Abstract

The invention provides a video compression method. The video compression method comprises the following steps of: acquiring background images from the shooting continuous pictures, and respectively converting the background images and the continuous pictures into grey-scale maps; enabling the background images of the converted grey-scale maps and the continuous pictures respectively to execute difference calculation so as to obtain difference images; respectively converting the difference images into binary images according to the setting gradation threshold value; respectively obtaining motion object regions of the continuous pictures according to the bianry images, and respectively calculating co-ordinate parameters of background images of the motion object regions; and compressing images of the background images and the motion object regions and the corresponding co-ordinate parameters into a video file. The invention also provides a video compression system, and the background images, the background images, the images of the variational motion regions and the co-ordinate parameters corresponding to the background images are compressed into a video file; and the video file greatly reduces the video data quantity, and a computer which has lower hardware configuration can smoothly play.

Description

technical field [0001] The present invention relates to the technical field of video compression, in particular to a video compression method and system. Background technique [0002] At present, high-definition video has entered thousands of households, and its high-quality display brings viewers a real home theater audio-visual enjoyment, so many video files are made in high-definition video format, for example, 1080P30 high-definition video, among which 1080P30 is a video display format, the letter P means progressive scan, the number 1080 means there are 1080 horizontal scanning lines in the vertical direction, the number 30 means the frame rate is 30 frames per second (FPS), and the screen resolution reaches 1920*1080 . [0003] As can be seen from the above description, for the video files produced by the high-definition images taken by the existing technology, to play these video files, a large amount of data needs to be processed in real time, and for computers whos...
