Embodiment Construction

[0026] The present invention provides a monitoring video secondary compression method based on connected domain analysis to obtain the monitoring video to be compressed,

[0027] Select the background frame,

[0028] If the difference between the current frame and the background frame is detected to exceed the set threshold, it is considered that there is a pixel of a moving object in the current frame, and the connected domain analysis is performed on the current frame through image morphology operations to mark the area where the moving object is located.

[0029] Save the area where the moving object is located as an image, while retaining the corresponding frame number and position of the current frame,

[0030] After packing the background frame and all frames with moving objects, the secondary compression of the surveillance video is completed.

[0031] In the method, the current frame with no background change and constant viewing angle is selected as the background fr...

Abstract

The invention discloses a monitoring video secondary compression method based on connected domain analysis, and relates to the technical field of video data processing. The method includes: obtainingsurveillance video to be compressed, and selecting background frames; if it is detected that the difference between the current frame and the background frame exceeds a set threshold value, considering that pixels of the moving object exist in the current frame; and carrying out connected domain analysis on the current frame after image morphological operation to label the area where the moving object is located, storing the area where the moving object is located as an image form, simultaneously reserving the frame number and the position of the corresponding current frame, and packaging thebackground frame and all the frames with the moving object to complete secondary compression of the monitoring video.

Description

technical field [0001] The invention discloses a surveillance video secondary compression method based on connected domain analysis, and relates to the technical field of video data processing. Background technique [0002] Video information is playing an increasingly important role in the Internet age. With the increasing popularity of monitoring equipment, a large amount of video data is generated. Long-term uninterrupted video storage consumes a lot of storage space, and most of the monitoring video data usually contains limited effective information, but occupies a large amount of storage space. It is not conducive to the long-term storage and use of videos. [0003] The invention discloses a monitoring video secondary compression method based on connected domain analysis. Based on compressing pixels with less changes between different frames, the changed pixels are extracted and retained through connected domain analysis, so as to achieve the purpose of secondary compr...
