own homographies. Let's take the
graffiti scene:</p>

<precode type="matlab">
dataset = datasets.VggAffineDataset('Category','graf');
</precode>

<p> Now we define set of feature extractors which we want to test.</p>

<precode type="matlab">
mser = localFeatures.VlFeatMser();
featureExtractors = {sift, thrSift, mser};
</precode>

<p> And finally loop over the feature extractors and selected images. </p>

<precode type="matlab">
imageAPath = dataset.getImagePath(1);
for detIdx = 1:numel(featureExtractors)
