I got a dataset for human tracking, since the pretrained models I found on MATLAB website were for detecting vehicles, but I am struggling to find the way to input my data as ground truth for my model. The dataset I got is ready and cropped. I need to input it as a table. I am using this code and getting the error 'The RowNames property must contain one name for each row in the table.'. I want the table to have 2 columns, one with image path and the other with its data matrix.

myFolder = 'C:\Users\Zewail\Downloads\rois\jpg_Extracted_PIDS';
dinfo = dir(fullfile(myFolder, '**/*.jpg'));
n = numel(dinfo);
T = table(cell(1, n), 'VariableNames', {'image'}, 'RowNames', {dinfo.name});
for K = 1 : n
  filename = dinfo(K).name;
  filecontent = imread(filename);
  T{filename,1} = filecontent;
end

The dataset I have is already cropped to the ROI, does not need labelling I believe. I am trying to create a table with the same format as vehicleDatasetGroundTruth.mat that is what I need help on. So basically I need a 2 column table, the first column containing the image's path and the second column containg the image as a matrix. This is the code I am using but I am getting the error "The RowNames property must contain one name for each row in the table."

myFolder = 'C:\Users\Zewail\Downloads\rois\jpg_Extracted_PIDS';
dinfo = dir(fullfile(myFolder, '**/*.jpg'));
n = numel(dinfo);
T = table(cell(1, n), 'VariableNames', {'image'}, 'RowNames', {dinfo.name});
for K = 1 : n
  filename = dinfo(K).name;
  filecontent = imread(filename);
  T{filename,1} = filecontent;
end
