MATLAB 视频Gamma灰度校正 自适应中值滤波代码实现

视频Gamma灰度校正代码实现：

clc;
clear all;
close all;

% 读取视频
v = VideoReader('test_video.mp4');

% 获取视频帧率
fps = v.FrameRate;

% 创建视频写入对象
writerObj = VideoWriter('gamma_correction_video.avi', 'Uncompressed AVI');
writerObj.FrameRate = fps;
open(writerObj);

while hasFrame(v)
    % 读取视频帧
    frame = readFrame(v);
    
    % 进行Gamma灰度校正，gamma值为0.5
    gamma = 0.5;
    frame = imadjust(frame, [], [], gamma);
    
    % 写入视频帧
    writeVideo(writerObj, frame);
end

% 关闭视频写入对象
close(writerObj);

自适应中值滤波代码实现：

clc;
clear all;
close all;

% 读取视频
v = VideoReader('test_video.mp4');

% 获取视频帧率
fps = v.FrameRate;

% 创建视频写入对象
writerObj = VideoWriter('adaptive_median_filter_video.avi', 'Uncompressed AVI');
writerObj.FrameRate = fps;
open(writerObj);

while hasFrame(v)
    % 读取视频帧
    frame = readFrame(v);
    
    % 进行自适应中值滤波，窗口大小为3x3
    frame = medfilt2(frame, [3 3]);
    
    % 写入视频帧
    writeVideo(writerObj, frame);
end

% 关闭视频写入对象
close(writerObj);
