Abstract
An apparatus and a method for recognizing a hand shape by using a finger pattern are disclosed. The throughput of data used to recognize a hand shape is reduced and the hand shape can be quickly recognized by setting in advance a finger pattern in accordance with one or more hand shapes, calculating edges for each pixel line of an input image, detecting finger feature data by using a preset feature reference value, detecting a finger candidate pattern by using the detected finger feature data, and recognizing a hand shape corresponding to a finger pattern that matches the detected finger candidate pattern.
Claims12
An apparatus for recognizing a hand shape by using a finger pattern, the apparatus comprising:
- a memory for storing a preset finger pattern according to each hand shape in accordance with one or more hand shapes;
- and
- a controller for calculating edges for each pixel line within an input image, detecting finger feature data according to a preset feature reference value by using the calculated edges, detecting a finger candidate pattern by using the detected finger feature data, and outputting a hand shape corresponding to a finger pattern that matches the detected finger candidate pattern among finger patterns stored in the memory as a recognition result.
A method of recognizing a hand shape by using a finger pattern in a hand shape recognition apparatus, the method comprising:
- storing a preset finger pattern according to each hand shape in accordance with one or more hand shapes;
- calculating edges for respective pixel lines within an input image;
- detecting finger feature data according to a preset feature reference value by using the calculated edges;
- detecting a finger candidate pattern by using the detected finger feature data;
- and
- outputting a hand shape corresponding to a finger pattern that matches the detected finger candidate pattern among finger patterns stored in a memory as a recognition result.
