Computer Vision & Digital Image Processing Dr. David Jeff Jackson Electrical & Computer Engineering The University of Alabama Electrical & Computer Engineering Dr. D. J. Jackson Lecture 2-1 Elements of visual perception • Goal: help an observer interpret the content of an image • Developing a basic understanding of the visual process is important • Brief coverage of human visual perception follows – Emphasis on concepts that relate to subsequent material Electrical & Computer Engineering Dr. D. J. Jackson Lecture 2-2 Cross section of the human eye • Eye characteristics – nearly spherical – approximately 20 mm in diameter – three membranes • cornea (transparent) & sclera (opaque) outer cover • choroid contains a network of blood vessels, heavily pigmented to reduce amount of extraneous light entering the eye. Also contains the iris diaphragm (2-8 mm to allow variable amount of light into the eye) • retina is the inner most membrane, objects are imaged on the..
