1. A method for segmenting an eye image to identify portions of the eye image containing iris pattern data comprising: receiving a frame of eye image data; convolving the eye image data with a predetermined matrix of coefficients to produce filtered eye image data, the predetermined matrix of coefficients being configured to produce peak points in the filtered eye image data at positions where glare is not present in the eye image data; comparing the filtered eye image data to a threshold; identifying a number of peak points in the filtered eye image data, the identified peak points in the filtered eye image data corresponding to positions of no glare in the eye image data; and segmenting the eye image data to identify portions of the frame containing iris pattern data only in response to at least one peak point being present in the filtered eye image data.
