Facial recognition system

  1. 1. Facial recognition system
  2. 2. Facial recognition system <ul><li>A facial recognition system is a computer application for automatically identifying a person from a digital image or a video frame from a video source. </li></ul>
  3. 3. Facial recognition system <ul><li>How facial recognition is done </li></ul><ul><li>Comparing selected facial features from the image and a facial database. </li></ul>
  4. 4. Facial recognition system <ul><li>Main Application </li></ul><ul><li>security systems </li></ul>
  5. 5. Facial recognition system <ul><li>Techniques : Traditional </li></ul><ul><li>An algorithm may analyze the relative position, size, and/or shape of the </li></ul><ul><li>eyes, </li></ul><ul><li>nose, </li></ul><ul><li>cheekbones, and </li></ul><ul><li>jaw. </li></ul><ul><li>These features are then used to search for other images with matching features. </li></ul>
  6. 6. Facial recognition system <ul><li>Techniques : 3-D </li></ul><ul><li>uses 3-D sensors to capture information about the shape of a face. </li></ul><ul><li>This information is then used to identify distinctive features on the surface of a face, such as the contour of the eye sockets, nose, and chin. </li></ul><ul><li>(contour=outline) </li></ul>
  7. 7. Facial recognition system <ul><li>Techniques : 3-D </li></ul><ul><li>advantages </li></ul><ul><li>it is not affected by changes in lighting like other techniques. </li></ul><ul><li>It can also identify a face from a range of viewing angles. </li></ul>
  8. 8. Facial recognition system <ul><li>Techniques : Skin texture analysis </li></ul><ul><li>Skin texture analysis turns the </li></ul><ul><li>unique lines, </li></ul><ul><li>patterns, and </li></ul><ul><li>spots </li></ul><ul><li>apparent in a person’s skin into a mathematical space. </li></ul>
  9. 9. Facial recognition system <ul><li>Techniques : Skin texture analysis </li></ul><ul><li>With the addition of skin texture analysis, performance in recognizing faces can increase 20 to 25 percent. </li></ul>
  10. 10. Facial recognition system <ul><li>Applications </li></ul><ul><li>The Australian Customs Service has an automated border processing system called SmartGate that uses facial recognition. </li></ul><ul><li>The system compares the face of the individual with the image in the e-passport microchip, certifying that the holder of the passport is the rightful owner. </li></ul>
  11. 11. Facial recognition system <ul><li>Applications </li></ul><ul><li>Law enforcement agencies in the world use face recognition system databases in their forensic investigative work. </li></ul><ul><li>U.S. Department of State uses face recognition systems for visa processing. </li></ul><ul><li>Mexican govt employed facial recognition software to prevent voter fraud. </li></ul>
  12. 12. Facial recognition system <ul><li>Limitations </li></ul><ul><li>Face recognition perform well at full frontal faces and 20 degrees off. </li></ul>
  13. 13. Facial recognition system <ul><li>Limitations </li></ul><ul><li>Other conditions where face recognition does not work well include </li></ul><ul><li>poor lighting, </li></ul><ul><li>sunglasses, </li></ul><ul><li>long hair, or </li></ul><ul><li>other objects partially covering the subject’s face, and </li></ul><ul><li>low resolution images. </li></ul>
