Embodiment Construction

[0028] With the development of movies, whether it is the restoration of old movies or the production of new movies, it is faced with the increase of data volume, the increase of CPU (Central Processing Unit, central processing unit) load or the unreliability of hard disk storage. Random frame drop or bad frame, once this kind of bad frame is packaged into a digital movie package for projection, it will cause unacceptable projection failure. At present, there are mainly two methods for detecting bad frames. One is to manually pick out possible bad frames by careful observation with human eyes; the other is to automatically detect bad frames by computer, by determining The difference between identifies bad frames.

[0029] However, the existing method of manually detecting bad frames is extremely fatigue-intensive and cannot meet the growing demand for film development. However, in the existing automatic detection of bad frames, it is easy to misidentify the video frames of nor...

Abstract

The invention provides a bad frame automatic detection method and device, equipment, a storage medium and a program product, and relates to the video processing technology, and the method comprises the steps: obtaining the information of each frame of picture in a to-be-detected video, and determining the difference between adjacent frames according to the information of each frame of picture; according to a preset fuzzy inference rule, performing correlation analysis on the difference between the adjacent frames to obtain an inter-frame correlation result; and determining a bad frame according to an inter-frame correlation result among the frames of pictures. According to the scheme provided by the invention, automatic detection of the bad frame can be realized, and the detection efficiency is improved; and moreover, correlation analysis is carried out on the difference of the adjacent frames by applying a fuzzy reasoning technology, the difference of the adjacent frames is the difference between the current frame and the front and back frames, the misjudgment that the video frame subjected to normal shot conversion in the video is mistakenly recognized as a bad frame can be effectively avoided through the mode, and then the video frame automatic detection efficiency is improved.

Description

technical field [0001] The present application relates to video processing technology, and in particular to a bad frame automatic detection method, device, equipment, storage medium, and program product. Background technique [0002] At present, with the development of movies, whether it is old movie restoration or new movie production, they are faced with random frame loss or broken frames caused by the increase of data volume, increase of CPU load, or unreliable hard disk storage. Frame, once this kind of bad frame is packaged into a digital movie package for projection, it will produce unacceptable projection failures. [0003] There are mainly two methods for detecting bad frames in the prior art, one is to pick out possible bad frames manually by careful observation with human eyes; the other is to automatically detect bad frames by computer, by determining the continuous Differences between frames identify bad frames. [0004] However, the existing method of manually...
