ABSTRACT:
The present invention discloses a system for and method of calculating pressure differences using a finger sensor. A finger sensor system in accordance with the present invention comprises a finger sensor for capturing first and second of sets of image data by contacting the finger sensor and means for providing a statistical comparison between the first and second sets of image data to determine a total pressure difference. The means for providing a statistical comparison comprises a means for generating first histogram data from the first set of image data and second histogram data from the second set of image data. The means for providing statistical data correlates peaks of the first and second histogram data and also determines differences between variances of the first and second sets of image data.
