Referring to fig. 1, fig. 1 provides a mobile terminal, which may specifically be a smart phone, where the smart phone may be a mobile terminal of an IOS system, an android system, and the mobile terminal may specifically include: the device comprises a processor, a memory, a camera and a display screen, wherein the components can be connected through a bus or in other ways, and the application is not limited to the specific way of the connection.
Referring to fig. 2, fig. 2 provides a video photographing error correction method, which is shown in fig. 2 and is performed by the mobile terminal shown in fig. 1, and which includes the steps of:
step S201, a mobile terminal receives a short video shooting request of a user and executes short video shooting to obtain a first video file;
step S202, the mobile terminal extracts background music of the first video file and determines a first time period and a second time period corresponding to the same paragraph in the background music;
the background music may be regular music, and the same section, i.e. the section with the same lyrics inside the music, such as "learning cat shout" we learn cat shout together, and meow "belongs to the same section, and has the same section for most of music.
Step S203, comparing the second video and the third video in the first video file of the mobile terminal in the first time period and the third video in the second time period to determine different parts of the second video and the third video, and performing error correction processing on the different parts of the first video file to obtain an error-corrected fourth video file.
According to the technical scheme, after the shot first video file is determined, the second video and the third video of the same section in the first video file are compared to determine different parts, and then the different parts are corrected, so that the error correction processing on the video can be realized.
The principle of the application is that for shooting videos, the videos with the same action can be directly corrected on the basis that the videos with the same action are provided, and the action with the same paragraph is the same through analysis of big data, so that different parts are determined by comparing the videos corresponding to two same paragraphs, and then the fourth video file after error correction can be obtained through error correction processing of the different parts, so that the experience degree of a user on video processing is improved, and shooting is not needed again.
The determining of the different portions of the second video and the third video by comparing the second video and the third video may specifically include:
dividing the second video into n parts (n is the lyric word number or letter number of the same paragraph) according to each word of the lyric of the same paragraph, dividing the third video into n parts according to each word of the lyric of the same paragraph, comparing the video frames of the two parts of the same word to determine whether the video frames are consistent, if so, determining the video frames are the same part, if not, determining the video frames are different parts.
The above comparison of the video frames of two parts of the same word to determine whether the video frames are consistent can be determined by the existing video comparison method.
Optionally, the performing error correction processing on the different parts of the first video file to obtain an error-corrected fourth video file may specifically include:
deleting videos of the time periods corresponding to the different parts of the first video file to obtain an error-corrected fourth video file;
or selecting the videos of the first time period and the second time period of the first video file as the second video or the third video.
The first way is to delete different parts directly, so that it is not necessary to determine which different parts belong to the wrong place, which has the disadvantage that the video effect is affected, and the second way is to select the same video in the same time period, because the video action is the same for the same time period, this selection will improve the video effect.
The manner of selecting the second video or the third video may specifically be that the fluency of the second video and the third video is determined, and the second video with higher fluency is selected to replace the third video with lower fluency.
The method for determining fluency may specifically be that adjacent frames of the second video are compared to determine whether the adjacent frames are the first number of consistent image frames, and adjacent frames of the third video are compared to determine whether the adjacent frames are the second number of consistent image frames, and if the first number is smaller than the second number, it is determined that the fluency of the second video is greater than that of the third video.
The principle is based on the principle that for video shooting, the more consecutive the motion is, the smaller the probability that the adjacent frames are consistent, whereas if there is an error, the person has a certain pause at the time of the erroneous motion, so that the same adjacent frames occur, and the more such cases, the poorer the fluency is.
Optionally, the method may further include:
and carrying out flattening processing on the video frames with double chin in the fourth video file.
The above-mentioned flattening processing of the video frame with double chin may specifically include:
extracting a p video frame of a fourth video file, obtaining a p video frame line route, determining a region with 2 adjacent line lines and the distance between the 2 line lines being less than a set distance as a region to be determined, constructing an equidistant line of lambda line routes for the region to be determined, extracting pictures between the equidistant lines, comparing and determining whether the two lines are consistent, if so, determining that the two lines are consistent (if the two lines are non-double chin regions, the pictures are consistent, the picture comparison method can be realized through the existing comparison method), determining that the region to be determined is non-double chin regions, if not, determining that the two lines are non-double chin regions (if the two lines are non-uniform in distribution of meat, pictures in each region are different), determining that the region to be determined is double chin regions, constructing an upper equidistant line in the upper region of the double chin regions, extracting a gamma picture between the upper equidistant line and the upper line, and replacing the gamma picture with the gamma line after extending downwards by lambda-1 (namely, each equidistant line is replaced by the gamma picture), replacing the gamma picture with the gamma picture in the gamma line region to And (6) processing.
The obtaining of the pth video frame texture line may specifically include:
marking the RGB values of all pixel points of the pth video frame into different colors, determining different color line segments in the same color, if the number of the different color line segments in the same color exceeds 2, obtaining the distance between the different color line segments, and if the distance is smaller than a set distance threshold, determining the different color line segments as grain lines.
For the line path, it divides the skin into a plurality of areas, the RGB value of the areas is the same because it is the skin, then when marking with color, the color of the skin is the same color, but for the line path, because of its folding and light, the line path is different from the RGB value of the skin, because of marking different color, the color of the line path is inconsistent with the color of the skin area, and it is a line segment, in addition, the line path with double chin has at least 2 or more, therefore the number is also more than 2. The grain lines can be distinguished by this method.
Referring to fig. 3, fig. 3 provides a terminal including: a camera, a processor and a display screen,
the camera is used for executing short video shooting to obtain a first video file when the display screen acquires a short video shooting request of a user;
the processor is used for extracting background music of the first video file and determining a first time period and a second time period corresponding to the same paragraph in the background music;
the processor is further configured to compare a second video in a first time period and a third video in a second time period in the first video file with the third video to determine different portions of the second video and the third video, and perform error correction processing on the different portions of the first video file to obtain an error-corrected fourth video file.
