Hello,
I am writing a code to extract HOG features with the hope of using MATLAB to recognize a picture taken with a webcam. The code that I am having trouble with is code that is borrowed from the Face Recognition with MATLAB seminar by Avi Nehemiah. My pertinent code is as follows:
faceDatabase = imageSet('MarioImageDatabase',"recursive");
training=faceDatabase;
trainingFeatures = zeros(size(training,2)*training(1).Count,7056);
featureCount = 1;
for i=1:size(training,2)
for j = 1:training(i).Count
trainingFeatures(featureCount,:) = extractHOGFeatures(read(training(i),j));
trainingLabel{featureCount} = training(i).Description;
featureCount = featureCount + 1;
end
personIndex{i} = training(i).Description;
end
faceClassifier1=fitcecoc(trainingFeatures,trainingLabel)
I am getting the error "Unable to perform assignment because the size of the left side is 1-by-7056 and the size of the right side is 1-by-213444"
The problem is with the line:
trainingFeatures(featureCount,:) = extractHOGFeatures(read(training(i),j));
I have tried changing the number of the .Count in the "trainingFeatures=zeros..." line, but if I change it to 213444 it says the left side is 213444 and the right side is 7056. So it appears that the numbers can be changed, I am just unsure how to get them to equal one another.
For reference, the image set is 3 photos.
The variables in my workspace and their values are as follows:
faceDatabase 1x1 imageSet
featureCount 1
i 1
j 1
training 1x1 imageSet
trainingFeatures 3x213444 double
if I change the .Count to 7056 then the trainingFeatures variable is 3x7056 double
Can you please help me make this work? Thank you in advance.
