Hello, i have extracted surf features from multiple images using the following code.But only the last image feature value is stored in the feature variable used in the code. how to get all the feature vector values..
Thank you... Code:
srcFiles = dir('F:\MTECH\MATLAB\Begin\photos\*.jpg');
for i = 1 : length(srcFiles)
filename = strcat('F:\MTECH\MATLAB\Begin\photos\',srcFiles(i).name);
I1 = rgb2gray(imread(filename));
points1 = detectSURFFeatures(I1);
[features2, valid_points1] = extractFeatures(I1, points1);
figure; imshow(I1); hold on;
plot(valid_points1.selectStrongest(10),'showOrientation',true);
columnvector = rand(1,64);
finalFeature = sum(columnvector(:));
sprintf('%s %d','finalFeature = ' , finalFeature)
end

finalFeature(i) = sum(columnvector(:));
sprintf('%s %d','finalFeature = ' , finalFeature(i))

I'm also a bit confused with rand(). It shows that my final features resulted differently every time we run the code.

I think the line with the rand() is "dummy code", put in to allow the framework to be developed but intended for replacement later.
