Size functions, a fairly new class of topological transforms, are used to implement SketchUp, a demonstrative classifier of free-hand drawn sketches. Sketches are drawn without a template and in total freedom. Four different such transforms cooperate to allow recognition in a seven item list of tools. 207 drawings have been examined, with 87.9% of success, 8.7% of rejection, 3.4% of errors. The training set is very small: 66 drawings; none of the drawers was common to the training and test sets.

Abstract
Size functions, a fairly new class of topological transforms, are used to implement SketchUp, a demonstrative classifier of free-hand drawn sketches. Sketches are drawn without a template and in total freedom. Four different such transforms cooperate to allow recognition in a seven item list of tools. 207 drawings have been examined, with 87.9% of success, 8.7% of rejection, 3.4% of errors. The training set is very small: 66 drawings; none of the drawers was common to the training and test sets.File in questo prodotto:
