In recent years due to improvements of technology within automobile industry, design process of advanced driver assistance systems for collision avoidance and traffic management has been investigated in both academics and industrial levels. Detection of traffic signs is an effective method to reach the mentioned aims. In this paper a new intelligent driver assistance system based on traffic...

Abstract Background Minimally invasive spine surgery is dependent on accurate navigation. Computer-assisted navigation increasingly used in minimally (MIS), but current solutions require the use of reference markers surgical field for both patient and instruments tracking. Purpose To improve reliability facilitate clinical workflow, this study proposes a new marker-free tracking framework based...

In this paper analysis and comparison of various methods for text detection is carried by using canny edge detection algorithm and MSER based method along with the image enhancement which results in the improved performance in terms of text detection. In addition, we improve current MSERs by developing a contrast enhancement mechanism that enhances region stability of text patterns to remove th...

Here we developed a MATLAB based Graphical User Interface for people to check the information of desired books in real-time. The GUI allows user to take photos of the book cover. Then it will automatically detect features of the input image based on MSER algorithm, then it will filter out non-text features based on morphological difference between text and non-text regions. In order to further ...

The invariant feature detectors are essential components in many computer vision applications, such as tracking, simultaneous localization and mapping (SLAM), image search, machine vision, object recognition, 3D reconstruction from multiple images, augmented reality, stereo vision, and others. However, it is very challenging to detect high quality features while maintaining a low computational ...

Digital Forensic is a branch of forensic science which is related to computer crime. It deals with the investigation and recovery of material found in digital devices. Digital images and videos are the most important part of digital forensics as they are the prime evidences in law issues or in mass media. So the loyalty of the digital image is important. Due to the rapid increase and easy acces...

Generally, the images captured by Camera has many different shapes, sizes, colours, text, non-text etc regions which very complex the Camera-based scene images usually have background which is very complex. The existing system is very sensitive to font scale changes and background interference with low accuracy. The most important aim of this system is based on character recognition method. Sep...
