Load training data that contains bounding boxes with labels for vehicles.
data = load('vehicleTrainingData.mat'); trainingData = data.vehicleTrainingData;
Add fullpath to the local vehicle data folder.
dataDir = fullfile(toolboxdir('vision'), 'visiondata'); trainingData.imageFilename = fullfile(dataDir,... trainingData.imageFilename); blds = boxLabelDatastore(trainingData(:,2:end));
Read a couple of times, before looking at the progress.
read(blds); read(blds);
See the progress made by the boxLabelDatastore.
