This paper presents a new real time lane detection and tracking system which succeeds in sharp curved roads. The Warp Perspective Mapping (WPM) method was used to change the video image perspective to top view. A two dimensional Gabor filter and vertical pixel density calculation method was used to find initial lane regions. Second derivative approach of Composite Bezier spline fitting method calculates...
Image and video processing is indispensable for modern traffic surveillance applications. At this, the reliable detection of vehicles is an essential and also challenging task depending on versatile environment parameters. Many research works have been investigated in accurate pattern matching so far. Nevertheless, dealing with noise and variations in pattern shapes are still improvable key problems...
In a vehicle license plate identification system, plate region detection is the key step before the final recognition. This paper presents a license plate detection algorithm from complex background based on top-hat transform and wavelet transform. First, the vertical gradient of gray image is calculated and the region of license plate is standed out by using top-hat transformation. Then the horizontal...
