Problems solved by technology

However, when performing frame supplementation, when the search target suddenly appears or disappears in the preset frame image, the position of the search target in the supplementary frame image may be inaccurate, which may result in a video image formed by the video stream data after frame supplementation. The display fluency is not enough, or the motion display is blurred or stuck

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present application, the directional indications are only used to explain the position in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the...

Abstract

The invention discloses a video image processing method and a related device. The video image processing method comprises the steps of obtaining to-be-processed video image data, and determining a frame supplementing position of the video image data; detecting the position of each preset target in a frame image of the video image data in a bidirectional search mode, wherein the bidirectional searching mode is searching from front to back and from back to front according to the time sequence of the video frames; obtaining a motion track of each preset target based on the position of each presettarget in the frame image; determining the position of each preset target in a to-be-interpolated frame corresponding to the frame supplementing position according to the motion trail to form to-be-interpolated frame image data; and inserting the to-be-inserted frame image data into the frame supplementing position to form the video image data after frame supplementing. Through the scheme, the fluency of the video image formed by the video image data can be improved.

Description

technical field [0001] The present application belongs to the field of image processing technology, and in particular relates to a video image frame complementing method and a related device. Background technique [0002] In online video playback or online live broadcast, the user's terminal usually needs to receive the video stream data transmitted by the cloud server, decode the video stream data, and then display the corresponding image information on the terminal. Among them, the frame rate (Frame rate) is an important indicator of the display quality of the image information. The frame rate is the frequency (rate) at which bitmap images in units of frames appear continuously on the display. When the frame rate is higher, it can be expressed as the number of image frames refreshed per unit time, and for moving images, the motion display will be smoother. [0003] However, in the prior art, when the frame rate of the image information in the video stream data is not hig...
