Handheld Person Verification System Using Face Image

چکیده
This paper presents our newly developed wireless system for person verification based on the face verification technology. In our system, a handheld device cooperating with a client-server wireless network is used. Due to the limitation of the handheld device's computing power, most computations will be distributed to a remote control server. There are two main problems for implementing the system. One is the variations in lighting and background conditions. The other is that the camera on the handheld device can not be calibrated with the system in advance. For calibration on line, we use a three-point localization scheme for extracting appropriate face region according to the information of eyes and mouth. Furthermore, statistic based illumination normalization is used in preprocessing to decrease illumination influence under variant lighting conditions. Experiment shows the proposed system provides users a more flexible and feasible way to interact with the verification system through handheld device.

متن کاملsmart application for AMS using Face Recognition
Attendance Management System (AMS) can be made into smarter way by using face recognition technique, where we use a CCTV camera to be fixed at the entry point of a classroom, which automatically captures the image of the person and checks the observed image with the face database using android enhanced smart phone. It is typically used for two purposes. Firstly, marking attendance for student b...
متن کاملSaliency-Based Robust Correlation for Real-Time Face Registration and Verification
We propose a novel person verification system for real-time face identification. The main features of the system include accurate registration of face images using a robust form of correlation, a framework for global registration of a face database using a minimum spanning tree algorithm and a method for selecting a subset of features optimal for discrimination between clients and impostors. Th...
متن کاملAn Evolving Neural Network Model for Person Verification Combining Speech and Image
This paper introduces a method based on Evolving Connectionist Systems (ECOS) for person verification tasks. The method allows for the development of models of persons and their on-going adjustment based on new speech and face images. Some experimental person verification models based on speech and face image features are developed based on this method where speech and face image information ar...
متن کاملDetermining Effective Features for Face Detection Using a Hybrid Feature Approach
Detecting faces in cluttered backgrounds and real world has remained as an unsolved problem yet. In this paper, by using composition of some kind of independent features and one of the most common appearance based approaches, and multilayered perceptron (MLP) neural networks, not only some questions have been answered, but also the designed system achieved better performance rather than the pre...
