Real-Time Depth-Based Hand Detection and Tracking

Algorithm 2

Classifier algorithm.

while 𝐹_𝑖>𝐹_desired

(1) Select the best classifier satisfying 𝑑_𝑟≥𝐷_desired and min(𝑒_𝑟).

(2) If 𝑒_𝑟≥0.5 then decrease 𝐷_desired and go step (1).

(3) Evaluate current cascaded classifier and update 𝐹_𝑖.

(4) 𝑁←∅.

(5) Include false positive samples and positive samples in set 𝑁.
