Vehicle Detection Method using Haar-like Feature on Real Time SystemSungji Han, Youngjoon Han and Hernsoo Hahn
Introduction
•HYPOTHESIS GENERATION• Detecting the distant region using a shadow feature
• Detecting vertical edge using Haar-like feature
• Determining the candidate regions
•HYPOTHESIS VERIFICATION• Verification using complexity of vehicles
• Final verification using vehicle’s symmetric feature
HYPOTHESIS GENERATION
Detecting the distant region using a shadow feature
• Brightness normalization
Detecting the distant region using a shadow feature
• Determining the shadow point in each height.
Detecting vertical edge using Haar-like feature
•Haar-Like Feature
•Better than Sobel and Prewitt
Detecting vertical edge using Haar-like feature
•Compare to Sobel result
Determining the candidate regions
•HYPOTHESIS VERIFICATION
Verification using complexity of vehicles
Final verification using vehicle’s symmetric feature
