Title: Car Recognition Through SIFT Keypoint Matching


1
Car Recognition Through SIFT Keypoint Matching
Third Quarter Report
Drew Stebbins, Pd. 6
2
Background
  • License plate tracking technology
  • Need for civilian vehicle recognition
  • Object detection techniques
  • SIFT keypoint matching

3
Problem statement
  • Car recognition
  • fast moving
  • multi-coloured
  • complex shapes
  • must identify in real-time

4
Region of Interest Identification
  • Hough circle transform
  • multiple passes

5
(No Transcript)
6
SIFT keypoint matching
  • Keypoint detection
  • scale-space extrema detection
  • keypoint localization
  • orientation assignment
  • keypoint descriptor

7

8
SIFT keypoint matching
  • Matching to database images
  • nearest-neighbour identification based on
    keypoint description

9
Expectations
  • side profile car recognition and categorization
  • invariant to lighting changes, also small amounts
    of rotation, translation
  • multiple cars
  • moderate detection speed

10
Progress
  • Region of interest identification
  • Hough transform circle detector
  • Scale space extrema detection
  • Gaussian smoothing function and
    difference-of-Gaussian

11
Plan for Fourth Quarter
  • Finish implementation of SIFT keypoint detection
    algorithm
  • Test recognition accuracy on database of testing
    images taken from TJ student parking lot
