Problems solved by technology
However, encoding according to the above two quantization methods may cause the secondary picture content to be encoded too finely, while the key picture content cannot be encoded more finely, that is, the equipment encoding resources cannot be allocated reasonably. As a result, the viewing experience of the encoded video picture is low, and the picture quality is poor

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] The embodiment of the present invention provides a video encoding method, and the execution body of the method may be any network device capable of processing video frame images. The network device can be used to analyze the acquired video frame image, and encode the video frame image based on the image analysis result, so that the original analog data can be converted into digital data, so as to facilitate the transmission and storage of video data. During the encoding process, the network device can encode different image areas in the same video frame image with different levels of fineness, so that different image areas in the same video frame image can have different levels of picture quality. The above-mentioned network dev...

The invention discloses a video coding method and device, and belongs to the technical field of video processing. The method comprises the following steps: extracting a to-be-coded frame image of a target video, and determining a coding weight corresponding to each image region in the to-be-coded frame image through an image analysis technology; setting a quantization parameter corresponding to each image area according to the coding weight corresponding to each image area; and encoding the to-be-encoded frame image based on the set quantization parameter corresponding to each image region. Byadopting the method and the device, coding resources can be distributed more reasonably, and the picture quality of the coded video and the video watching experience can also be improved on the whole.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a video encoding method and device. Background technique [0002] Image acquisition devices such as cameras can generate original video data after collecting image information. The original video data is composed of a large number of frame images arranged in sequence, and its data volume is very large. In order to facilitate the transmission and storage of video, video coding technology can be used to encode and compress the original video data first, so as to remove redundant information in the original video data, and then transmit or store the encoded video data. [0003] Existing video coding mainly includes intra-frame coding and inter-frame coding: during intra-frame coding, discrete cosine transform, quantization, and entropy coding can be sequentially performed on frame images, so that compressed image data can be obtained; When performing inter-frame co...
