Problems solved by technology

[0008] The first purpose of the present invention is to propose a video image transmission processing method for the defects of poor video quality and serious packet loss in the existing video transmission technology that cannot protect important data, so as to realize face information and non-face information in real time. Differentiate treatment during network transmission to improve video transmission quality and transmission effect
[0009] The second purpose of the present invention is to propose a video image transmission processing device for the defects of poor video quality, inability to protect important data when packet loss is serious, and high complexity in the existing video transmission technology to realize face information and non-human Face information is treated differently during network transmission to improve video transmission quality and transmission effect

Embodiment 2

[0052] Embodiment 2 refines Embodiment 1 in the step of dividing the input video image into face parts and non-face parts. While having the beneficial technical effect of Embodiment 1, due to the use of the H.264 encoding algorithm The FMO mode effectively limits the face within a minimum rectangle, so that the allocation rate of coding bits reaches the highest. The FMO mode type of H.264 is used to segment the face part and the non-face part. In the face video In the image, the human face is often the area of ​​interest to everyone, and it has a high importance. Extracting the human face and encoding and marking it separately, instead of processing the entire image in the same way, is conducive to more accurate processing under the condition of limited channel resources. Effective use of channel resources to achieve better transmission results. In addition, because the same H.264 encoding algorithm can be used to encode face segments and non-face segments with different preci...

Embodiment 3

[0058] Embodiment three refines embodiment one in the step of dividing the input video image into a human face part and a non-human face part, so it has the beneficial technical effect of embodiment one; embodiment three adopts MPEG-4 to encode, Compared with the second embodiment, the cost of object segmentation and shape coding is higher, but the present invention can also be implemented through MPEG-4, and is not limited to H.264 to distinguish the priority of human face and non-human face parts in video images.

[0059] Figure 6 It is a flow chart of a video image transmission processing method according to Embodiment 4 of the present invention. Embodiment 4 is a preferred implementation of a video image transmission processing method of the present invention. The video image is divided into face Fragmentation and non-face fragmentation, use H.264 to encode face fragments and non-face fragments with different precision, and set different priorities for the specific implem...

Embodiment 7

[0085] The seventh embodiment includes the receiving module 1, the detection processing module 2, the encoding module 3 and the transmission module 4 in the sixth embodiment, wherein the detection processing module 2 may include:

[0086] The detection and division sub-module 21 is used to obtain the minimum circumscribed rectangle of the human face in the video image according to the human face detection algorithm, the minimum circumscribed rectangle is used as the human face part, and the rest of the video image is used as the non-human face part, see image 3 and related instructions;

[0087] Fragmentation sub-module 22, for face part and non-human face part fragmentation, video image is divided into the fragmentation of human face part and the fragmentation of non-human face part;

[0088] The first priority processing sub-module 23 is used to set a high priority mark for the fragmentation of the human face part, and set a low priority mark for the fragmentation of the no...

Abstract

The invention discloses a video image transmission processing method and a device; wherein, the method includes that: the input video image is detected and the video image is divided into a face part and a non-face part; the face part and the non-face part are respectively set with different priorities; and the face part and the non-face part are transmitted. When network quality is poor or the packet loss rate is high, the face part with higher priority can be transmitted and specially protected. The invention can solve the defects that the video transmission technique in prior art cannot protect the key data when the video quality is poor and the packet loss rate is high; the video transmission quality and transmission effect are accordingly improved.

Description

technical field [0001] The present invention relates to video transmission technology in the field of wireless communication, in particular to a video image transmission processing method and device. Background technique [0002] With the continuous development of communication technology, users put forward more and more diversified demands on communication services, and wireless video communication is becoming the preferred communication method for more and more users. [0003] Wireless video communication is characterized by a large amount of data, high bandwidth stability requirements, and sensitivity to data loss. The above problems have caused the problem of poor image transmission quality in existing wireless video communication technologies. In wireless video communication, the two communicating parties pay more attention to the face information of the other party, and the degree of attention to the background part is significantly reduced. Therefore, a video communic...
