Manipulation of the Calibre of Air Weapon- A Case Study
Journal Title: International Journal of Forensic Sciences - Year 2018, Vol 3, Issue 2
Abstract
Bombay customs department seized air rifles of different calibre. In one of the air rifles (Evanix, Rainstorm) the calibre was mentioned to be .177”/ 4.5 mm and the same was sent to the laboratory for Forensic examination to ascertain its original calibre. The image processing and the pattern recognition technique, i.e image sharpening & edge detection, noise removal, pattern recognition and then, finally image recognition revealed the original calibre of the air rifle. The Gaussian filter was applied for the enhancement of the numbers [1]. Circles and straight lines are a common geometric structure of interest in computer vision applications. Hough transformation is used to locate circles and straight lines. This study also deals with The Arms Act 1959 read with the Arms Rules, New Delhi, 15th July, 2016, so as to understand the basic reasons for its tampering and manipulation.
