Embodiment 1

[0020] figure 1 It is a flow chart of a video image processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case where the region of interest (Region of Interesting, referred to as ROI) calculation and encoding processing is performed on the video image data provided by the data source. , the method is executed by a video image processing system, such as figure 2 As shown, the ROI calculation server 210 and at least one encoding server 220 are included. The two servers are preferably physically independent, but they can also be physically integrated into one server to realize the logical functions of the two servers respectively.

[0021] The method specifically includes the following steps:

[0022] Step 110, the ROI calculation server determines the ROI and non-ROI of the image in the video image data based on the set rules;

[0023] The above steps are used to determine the ROI and non-ROI of the image in the video image ...

Embodiment 2

[0033] image 3 A schematic diagram of the architecture of a video image processing system provided in Embodiment 2 of the present invention, the system includes an ROI calculation server 210 and at least one encoding server 220, image 3 Shown is the case comprising an encoding server 220, figure 2 Shown is the case where multiple encoding servers 220 are included. The ROI calculation server 210 and the encoding server 220 are physically set independently, and perform data interaction through wired or wireless means.

[0034] The architectural pattern of the system is not limited to figure 2 and image 3 As shown, there may be multiple implementation manners. For example, the ROI calculation server and the encoding server may also be physically integrated and arranged in one server to realize their logical functions respectively. The number of ROI calculation servers can be multiple, and there are many interactive connection relationships with each encoding server, so tha...

Abstract

The invention discloses a video image processing method and system. The method comprises the steps that an ROI calculating server determines the ROI and the non-ROI of images in video image data based on set rules; the ROI calculating server provides the video image data and ROI classification schemes of the video image data for at least one coding server; the coding server obtains coding demands and ROI quality control strategies and selects the ROI classification schemes and the ROI quality control strategies according to the coding demands; the video image data are coded according to the selected ROI classification schemes and the ROI quality control strategies. According to the video image processing method and system, the architectural pattern of separated operation of ROI calculating and video coding is provided. The ROI classification schemes and the ROI quality control strategies can be flexibly combined, and the different coding demands can be better handled. The ROI calculating and coding are operated separately, repeated calculating of the ROI classification schemes of the video image data is not needed, ROI calculating resources are saved, the operation efficiency is improved, and it is ensured that video programs are transmitted in real time.

Description

technical field [0001] Embodiments of the present invention relate to video processing technologies, and in particular, to a video image processing method and system. Background technique [0002] With the development of video technology and media communication technology, the dissemination and sharing of video image data has become an indispensable means of information sharing in people's work and life. [0003] In the face of massive video image data, in order to reduce the transmission bit rate, it is usually necessary to compress and encode the video image at the data source. Compression will cause a certain loss in the quality of the video image, and it is difficult to take into account the relationship between the transmission bit rate and the video quality. At the same time, for the same video image data provided by the same data source, different receivers will also have different quality requirements and transmission capacity limitations, which also put forward hig...
