Abstract
Tosolve the shifting
rotating and zooming problems of the in hand geometry recognition
a concept of coordinate domain transformation is put forward in this paper to redefine the hand geometry coordinate.The three affine changes in hand geometry recognition can be eliminated effectively
so the fixed poles widely used in hand geometry acquisition process can be removed to make the process more flexible
