Presentation Transcript

  1. Cynthia Atherton REU Program:Week 5 Presentation

  2. Topics • Test Results • Image sizes • Cluttered backgrounds • Consistent curve detections in different orientations • Plans for next week

  3. Image Sizes • Original test size: 320 x 240 • Additional test sizes: • 640 x 480 • 800 x 600 • 1024 x 768 • And the winner is…640 x 480

  4. Image Sizes 320 x 240 640 x 480

  5. Cluttered Backgrounds Get_points.cpp Curvefinder.c

  6. Consistent Detections • Tested hand in 8 orientations • Plain background • Textured background • Mixed results

  7. Plans • Test more backgrounds • Hand rotations on different backgrounds • Progressive backgrounds • Continue working with get_points.cpp (chevrons) software • How does software determine curves? • How does software apply chevrons? • Why are angle chevrons applied so stingy? • Why are some curves ignored?
