Can anyone help me to plot graph by using grid2image command by loading images and their references with their names from a single mat file with two different variables names. I have attached the code in which mat file is generated
start_path='F:\study\practise\New folder\2015';
topLevelFolder = start_path;
if topLevelFolder == 0
return;
end
filePattern_1 = sprintf('%s/**/HH/', topLevelFolder);
filePattern = sprintf('%s/*.tif', filePattern_1);
allFileInfo = dir(filePattern);
isFolder = [allFileInfo.isdir];
allFileInfo(isFolder) = [];
listOfFolderNames = unique({allFileInfo.folder});
numberOfFolders = length(listOfFolderNames);
fprintf('The total number of folders to look in is %d.\n', numberOfFolders);
totalNumberOfFiles = length(allFileInfo);
if totalNumberOfFiles >= 1
for k = 1 : totalNumberOfFiles
% Go through all those files.
thisFolder = allFileInfo(k).folder;
thisBaseFileName = allFileInfo(k).name;
fullFileName = fullfile(thisFolder, thisBaseFileName);
% fprintf(' Processing file %d of %d : "%s".\n', k, totalNumberOfFiles, fullFileName);
% To get images and their georeferencing
[A,R]=geotiffread(fullFileName);
Y= db2pow(A );
% % To apply median filter
B = medfilt2(Y,[100 100]);
%
% To apply block averaging
% meanFilterFunction = @(theBlockStructure) mean2(theBlockStructure.data(:)) * ones(2,2, class(theBlockStructure.data));
meanFilterFunction = @(theBlockStructure) mean2(theBlockStructure.data(:));
blockSize = [12 12];
blockyImage = blockproc(B, blockSize, meanFilterFunction);
blockyImage(isnan(blockyImage))=0;
X= pow2db(blockyImage);
% % To save images and their names as a single mat file
Alpha(k).name=thisBaseFileName;
Alpha(k).img=X;
%
% Get lat and lon of blocked images
R_blocked = R;
R_blocked.RasterSize = size(X);
% %To save georeferencing of all images as a single mat file
% R2.name=thisBaseFileName;
R2(k).name=thisBaseFileName;
R2(k).Georeferencing=R_blocked;
save('Preprocessed2015.mat','Alpha', 'R2');
clear X
end
else
end

I don't have geotiffread(). Is that in the Mapping Toolbox (which I don't have)?
