Automatic Recognition of Road Signs by Hough Transform: Road-GIS
The problem of road sign detection and recognition is very important in many practical problems, above all for road cadastral authorities. In this sense, an automatic application able to identify the kind of a road sign starting from common imageries such as photos could be very helpful. The main difficulty is due to a possible poor graphical definition of the imagery. In this case, a valid sup...
متن کاملMethane: signs of progress along the road.
Analyses of air bubbles within ice cores suggest that the concentration of atmospheric methane remained fairly steady from 1500 BC to 1700 AD. However, with the dawn of the Industrial Revolution atmospheric methane concentrations began to increase. Recent findings of Simpson et al. (2006) have shown that the growth in the concentration of tropospheric methane has leveled off based on air sampli...
متن کاملDetection and Tracking of Road Signs 1
In a visual driver-assistance system, road sign detection and tracking is one of the major tasks. This study describes an approach to detecting and tracking road signs appearing in complex traffic scenes. In the detecting phase, two neural networks are developed to extract color and shape features of traffic signs, respectively, from the input scene images. Traffic signs are then located in the...
متن کاملIncremental detection of text on road signs
This paper presents a framework for incremental detection of text from road signs. The approach efficiently incorporates tracking and detection mechanisms into the same framework. The proposed approach first finds a set of discriminative feature points and clusters them into different regions. We then select candidate sign planes by a combination of color and vertical plane models. Within detec...
متن کاملRobust Road Signs Segmentation in Color Images
This paper presents an efficient method for road signs segmentation in color images. Color segmentation of road signs is a difficult task due to variations in the image acquisition conditions. Therefore, a color constancy algorithm is usually applied prior to segmentation, which increases the computation time. The proposed method is based on a log-chromaticity color space which shows good invar...
