视频转图片，图片取大小

clc;clear;

obj=VideoReader('双闪.avi');

numFrames = obj.NumberOfFrames;% 帧的总数

for i=1:numFrames

im = read(obj,i);%读取第几帧

aaa=imresize(im,[628,800]);%设置图片大小

ae=aaa(21:548,:,:);%取RGB图片的一部分

%保存为 *.tif 图

imwrite(ae, ['D:\MATHWORKSHOP\vedio12\' num2str(i) '.tif']);

end

Excel文件的读写：

读：

[NUM,TXT,RAW]=xlsread('datacombinALL_20161103_01.xlsx',1,'A2:AQ329879');

写：

xlswrite('NewNoRepeat_20161104_01.xlsx',data,1,'A1');

excel2text:

ExcelPath = 'excelData/';

TextPath = 'textData/';

secondFile = dir(fullfile(ExcelPath,'*'));

secondFile = struct2cell(secondFile);

[~,n] = size(secondFile);

for excel_id=1:n-2

[NUM,TXT,RAW]=xlsread(strcat(ExcelPath,'A_',num2str(excel_id),'.xlsx'));

fp = fopen(char(strcat(TextPath,'Txt_',num2str(excel_id),'.txt')),'wt');

for txt_id=1:max(size(RAW))

fprintf(fp,'%s%c\n',char(TXT{txt_id,1}),'');%写入字符 写入换行符

end

fclose(fp);

disp_excel_id=char(strcat('excel_id=',num2str(excel_id)));

disp( disp_excel_id);

end

按文件夹读取文件

path = 'F:/MATLAB_workSpace/AIUI_challenge_cup/dataExcel/';

%% 读取文件夹 n-1

firstFile = dir(fullfile(path,'*'));

firstFile = struct2cell(firstFile);

firstnum = size(firstFile);

for firstk =0:firstnum(2)-1

firstx(firstk+1) = firstFile(1,firstk+1);

end

ExcelPath = cell(1,1);

%% 进一步读取文件夹里面的内容

for firstk = 1:firstnum(2)

if ~strcmp(char(firstx(firstk)),'.')

if ~strcmp(char(firstx(firstk)),'..')

newpath = char(strcat(path,'',firstx(firstk),'/'));

ExcelPath{firstk-2,1}= newpath;

end

end

end
