Description

Previous systems for human hand posture estimation have adopted clustered multi-layer database with narrowing of search space by its past estimation results. But once an estimated result at a time is out of the search space, the system can't find out a true value. Our system therefore has adopted non-clustered database with narrowing of search space, rather, coarse search at the first stage with some aspects of hand images, and accurate search at the second stage with HLAC. The experimental results showed that averaged estimation error is -4.51 degrees, and the candidates for accurate search at the second stage are reduced from 20,192 to 85.3, which indicates our system realizes the high accuracy and processing speed as previous system without using the past results.
