CS252A, Fall 2010 Computer Vision I Image Formation and Cameras Computer Vision I CSE 252A Lecture 3 CS252A, Fall 2010 Computer Vision I Announcements Assignment 0: “ Getting Started with Matlab ” is posted to web page, due Tuesday Read Forsyth & Ponce chapters 1 & 2 , Richard Szeliski p29-45. CS252A, Fall 2010 Computer Vision I The course Part 1: The physics of imaging Part 2: Early vision Part 3: Reconstruction Part 4: Recognition CS252A, Fall 2010 Computer Vision I Image Formation: Outline Factors in producing images • Projection Perspective/Orthographic Projection Vanishing points Projective Geometry Rigid Transformation and SO(3) • Lenses • Sensors • Quantization/Resolution • Illumination Reflectance and Radiometry CS252A, Fall 2010 Computer Vision I Earliest Surviving Photograph • First photograph on record, “la table service” by Nicephore Niepce in 1822. • Note: First photograph by Niepce was in 1816. CS252A, Fall 2010 Computer Vision I How Cameras Produce Images Basic process: photons hit a detector the detector becomes charged the charge is read out as brightness Sensor types: CCD (charge-coupled device) high sensitivity high power cannot be individually addressed blooming CMOS simple to fabricate (cheap) lower sensitivity, lower power can be individually addressed
