public class LineVectorizer
extends ShortLineBasedVectorizer

LineVectorizer is a vectorizer using short line of default length 5. You do a sequence of small lines, if 2 consecutive lines are close in direction you can merge them. But if they are far away in angle you create a new line. Also you can only have 2 direction within the same line, they are stored by cycle index.
