2 部分代码

function [ background_frame ] = BackgroundExt( input_video )% This script make a background frame based on the samples of the frames. That is, it takes the average of the % frames and save the result as the background frame% If you have the background frame, then you can use it directly. We are% using averaging because we do not have access to the background image,% and by averaging we can supress the effect of moving objects in the% resulting frame and have a better estimation of background frame.sample_step = 2;vid = VideoReader(input_video);%vid = VideoReader('sample.mov');%frame = vid.read(inf);Height = vid.height;Width = vid.width;nframes = vid.NumberOfFrames; %Number of framesbackground = zeros(Height,Width,3); %Initial Background Image%% First Stage: averaging over all of the background samplesfor i=1:sample_step:nframes-sample_step    background = background + double(read(vid,i));endbackground = sample_step*background/(nframes);%imshow(uint8(background));background_frame = background;end​
