Title: The Innovative Contributions of Barry McCullagh
Introduction
Barry McCullagh is a notable inventor based in Galway, Ireland. He has made significant contributions to the field of image acquisition technology, particularly in the area of eye imaging. With a total of four patents to his name, McCullagh's work has advanced the understanding and capabilities of iris recognition systems.
Latest Patents
One of McCullagh's latest patents is an image acquisition system for off-axis eye images. This innovative system determines first and second sets of points that define the iris-pupil boundary and the iris-sclera boundary in an acquired image. It then fits respective ellipses to these points and determines a transformation to convert one of the ellipses into a circle on a corresponding plane. Using this transformation, the system transforms the selected ellipse into a circle and the other ellipse into a transformed ellipse on the plane. Furthermore, it defines an iris grid by interpolating a plurality of ellipses between the circle and the transformed ellipse. The system moves the determined grid ellipses onto the iris in the image using an inverse transformation and extracts an iris texture by unwrapping the iris and interpolating image pixel values at each grid point defined along the grid ellipses.
