In this paper, a modified segmentation algorithm for printed Farsi words is presented. This algorithm is based on a previous work by Azmi that uses the conditional labeling of the upper contour to find the segmentation points. The main objective is to improve the segmentation results for low quality prints. To achieve this, various modifications on local baseline detection, contour labeling an...

This paper proposes a new method for detecting vehicles from an image. The method consists in three stages of segmentation, extraction of candidate window corresponding to a vehicle and detection of a vehicle. From the experimental results using 121 real images of road scenes, it is found that the proposed method can successfilly detect vehicles for 120 images among 121 images.

A novel algorithm for the recognition of Japanese road sign symbols with red annular boundaries is proposed. After detecting a red annular object using HSV color coordinates, a biologically inspired opponent-color filter is applied to extract the symbol parts of road signs. By applying discriminant analysis to the filter output, the inside region circumscribed by red annular boundary can be ext...

Real-time semantic segmentation is in intense demand for the application of autonomous driving. Most models tend to use large feature maps and complex structures enhance representation power high accuracy. However, these inefficient designs increase amount computational costs, which hinders model be applied on In this paper, we propose a lightweight real-time model, named Parallel Complement Ne...

Vision-based road detection plays a key role for Unmanned Ground Vehicles (UGVs) working in an unknown outdoor environment. The estimation of the vanishing point is a practical solution for general road detection using monocular vision, which however is not good enough for robust road detection in a campus environment due to the strong noises of texture orientations generated from roadside tree...

Road sign recognition is a driver support function that can be used to notify and warn the driver by showing the restrictions that may be effective on the current stretch of road. Examples for such regulations are 'traffic light ahead' or 'pedestrian crossing' indications. The present investigation targets the recognition of Malaysian road and traffic signs in real-time. Real-time video is take...

Road extraction plays an important role in many applications such as car navigation. However, the manual extraction of roads is a laborious and tedious task. Road extraction from satellite images has drawn considerable attention in last years due to the recent availability of commercial high-resolution optical satellite imagery. Road extraction strategies are usually classified into two categor...
