APPLICATION RESEARCH OF IMAGE-BASEDAUTOMATICALLY FOOTPRINT RECOGNITION SYSTEM
The key to identify footprint is the exact extraction of the characteristics of footprints and the correct identification if footprints images. The system will square the footprints in the database with the footsteps in line with the conditions one by one to calculate the characteristic parameters of the candidate tracks, and then draw the similarity of the footprints on the basis of the accurate entry and retrieval from their characteristic parameters. So we can overcome the two-definitional issues owing to different descriptions from different officers involved and focus on the technical problems of vague on-the-spot footprints enquiry. This paper presents an image-based footprints identification method. Application results show that the image-based automatic footprint identification system has the advantages of fast computing, good effect of feature extraction and efficient recognition.
