Feature characterization from infrared radiation

At least one computer readable storage medium comprising a set of instructions, which when executed by a processor, cause the processor to:

• automatically receive a feature infrared (IR) pattern corresponding to non-uniform IR radiation reflected by skin of a user feature and an object IR pattern corresponding to non-uniform IR radiation reflected by an object;
• automatically generate a modified IR pattern from the object IR pattern and to remove at least a part of the modified IR pattern from feature IR pattern;
• and
• automatically characterize the user feature based on the feature IR pattern.

A method comprising:

• automatically receiving a feature infrared (IR) pattern corresponding to non-uniform IR radiation reflected by skin of a user feature and an object IR pattern corresponding to non-uniform IR radiation reflected by an object;
• automatically generating a modified IR pattern from the object IR pattern and removing at least a part of the modified IR pattern from feature IR pattern;
• and
• automatically characterizing the user feature based on the feature IR pattern.
