Abstract:
1. An apparatus for recognizing gestures in a picture, using hardware, a computer system, or a combination of hardware and a computer system, comprising: a Hough transformer configured to identify arcs in the picture or in a pre-processed version of the picture as identified gesture elements so as to acquire information about the identified gesture elements; a gesture description creator configured to acquire a gesture description while using the information about the identified gesture elements; and a gesture classifier configured to compare the gesture description to a plurality of comparative gesture descriptions having gesture codes associated with them so as to provide, as the result of the comparison, a gesture code of a recognized gesture; wherein the Hough transformer is configured to identify a plurality of straight-line segments extending through the picture in various directions as identified gesture elements; wherein the Hough transformer is configured to provide information about a location, a length or a direction of an identified straight-line segment, and wherein the gesture description creator is configured to use the information, provided by the Hough transformer, about the identified straight-line segments for creating the gesture description; wherein the gesture description creator is configured to acquire as the gesture description a description of a gesture describing the gesture as an ordered listing of parameters of identified gesture elements.
