Once features have been detected, a local image patch around the feature can be extracted. This extraction may involve quite considerable amounts of image processing. The result is known as a feature descriptor or feature vector. Among the approaches that are used to feature description, one can mention N-jets and local histograms (see scale-invariant feature transform for one example of a local histogram descriptor). In addition to such attribute information, the feature detection s… WebbIn image processing, features can be gradient magnitude, color, grayscale intensity, edges, areas, and more. Feature vectors are particularly popular for analyses in image processing because of the convenient way attributes about an image, like the examples listed, can be compared numerically once put into feature vectors.
