Abstract
The present invention is directed to a method of determining vein patterns from a color image for personal identification, the method comprising forming a counterpart of the color image by applying a functional relationship obtained from optimization on the color image, wherein the counterpart of the color image comprises the vein patterns. An apparatus for determining vein patterns from a color image is also disclosed.
Claims20
A method of determining vein patterns from a colour image for personal identification, the method comprising:
- forming a counterpart of the colour image by applying a functional relationship obtained from optimization on the colour image, wherein the counterpart of the colour image comprises the vein patterns,
- wherein the functional relationship is formulated using a model modelling colour image and a counterpart of the modelling colour image, wherein the counterpart of the modelling colour image comprises modelling vein patterns.
A method of determining vein patterns from a colour image for personal identification, the method comprising:
- forming a counterpart of the colour image by applying a functional relationship obtained from optimization on the colour image, wherein the counterpart of the colour image comprises the vein patterns,
- wherein the functional relationship obtained from optimization is formulated using an approximate regression comprising a least-squares-error energy function with an optimal weight.
A method of determining vein patterns from a colour image for personal identification, the method comprising:
- forming a counterpart of the colour image by applying a functional relationship obtained from optimization on the colour image, wherein the counterpart of the colour image comprises the vein patterns,
- wherein the colour image comprises colour components;
- wherein the counterpart of the colour image comprises skin-characterizing variables;
- and
- wherein forming a counterpart of the colour image comprises determining distributions of the skin-characterizing variables to form the vein patterns.
An apparatus for determining vein patterns from a colour image for personal identification, the apparatus comprising:
- a determining unit configured to form a counterpart of the colour image by applying a functional relationship obtained from optimization on the colour image, wherein the counterpart of the colour image comprises the vein patterns,
- wherein the functional relationship is formulated using a modelling colour image and a counterpart of the modelling colour image, wherein the counterpart of the modelling colour image comprises modelling vein patterns.
