Problems solved by technology

[0002] Traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. When encoding all video frames indiscriminately, the resolution of the referenced video frames is the same, then The video frame can only refer to the reference frame of the same resolution, the use efficiency of the reference frame is not high, and the reference relationship is not flexible enough

Embodiment Construction

[0012] Such as figure 1 As shown, in one embodiment, an image coding method based on interpolation processing is provided. The image coding method based on interpolation processing specifically includes the following steps:

[0013] Step 1, obtain the current reference frame corresponding to the video frame to be encoded.

[0014] Wherein, the video frame to be encoded may be a video frame collected in real time, or may be a video frame corresponding to a stored video. The video frame to be encoded can be an input video frame in the input video frame sequence; the video frame to be encoded can also be a video frame obtained after processing the input video frame in the input video frame sequence according to a corresponding processing method, wherein, in the After the input video frame is processed according to the corresponding processing method, the resolution of the video frame to be encoded is smaller than that of the original input video frame. For example, the input vi...

Abstract

The application relates to an image encoding method based on interpolation processing. According to the image encoding method based on interpolation processing provided by the invention, after encodeddata corresponding to a to-be-decoded video frame and a current reference frame corresponding to the to-be-decoded frame are acquired, a pixel dividing interpolation manner of the current reference frame can be determined, the pixel dividing interpolation manner is employed to process the current reference frame according to resolution information of the current reference frame, resolution of thecurrent reference frame is adjusted, a target reference frame is obtained, and use efficiency of the reference frame is improved.

Description

technical field [0001] The present application relates to the technical field of image compression, in particular to an image encoding method based on interpolation processing. Background technique [0002] Traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. When encoding all video frames indiscriminately, the resolution of the referenced video frames is the same, then The video frame can only refer to the reference frame of the same resolution, the use efficiency of the reference frame is not high, and the reference relationship is not flexible enough. Contents of the invention [0003] An embodiment of the present invention provides an image coding method based on interpolation processing, including: [0004] Obtain the current reference frame corresponding to the video frame to be encoded; [0005] Determine the sub-pixel interpolation mode; the sub-pixel interpolation mode is one of the direct sub-pixel interp...
