清理代码,使其更加规范整洁:
```matlab
clear all;
close all;
clc;
%% 读取视频
videoFile = 'D:\R2021a\gxl\DataAlignBeam1\beamtestcut1.avi'; % 设置视频文件路径
videoObj = VideoReader(videoFile); % 创建VideoReader对象
numFrames = videoObj.NumFrames; % 获取总帧数
%% 旋转图像+框选区域
outputVideoFile_rotated = 'D:\R2021a\gxl\DataAlignBeam1\beamtestcut1_rotated.avi';
outputVideo_rotated = VideoWriter(outputVideoFile_rotated);
open(outputVideo_rotated);
outputVideoFile_boxed = 'D:\R2021a\gxl\DataAlignBeam1\beamtestcut1_rotated_boxed.avi';
outputVideo_boxed = VideoWriter(outputVideoFile_boxed);
open(outputVideo_boxed);
% 框选位置
x = 100; % 框选区域左上角 x 坐标
y = 100; % 框选区域左上角 y 坐标
width = 200; % 框选区域宽度
height = 150; % 框选区域高度
for frameIndex = 1:numFrames
% 读取视频帧
frame = read(videoObj, frameIndex);
% 进行旋转操作(示例为顺时针旋转90度)
rotatedFrame = imrotate(frame, 90);
% 在旋转后的帧上框选特定位置
boxedFrame = rotatedFrame;
boxedFrame(y:y+height, x:x+width, :) = 255; % 设置框选区域为白色
% 续写框选后的视频帧
writeVideo(outputVideo_boxed, boxedFrame);
end
close(outputVideo_rotated);
close(outputVideo_boxed);
```
这样,代码更易读,变量名与功能相对应,注释也更清晰。
