Biometric authentication provides a high security and reliable approach to be used in security access system. However, this authentication method has not been widely implemented in a resource-constrained embedded system. In this project, we investigate a method of personal authentication based on infrared vein pattern in the back of the hand, targeted for embedded system which is implemented in Altera...
A number of techniques have been proposed in the literature for phoneme based speech recognition system. In this paper, a technique for automatic phoneme recognition using zero-crossings (ZC) and magnitude sum function (MSF) is proposed. The number of zero-crossings and magnitude sum function per frame are extracted and a minimum distance classifier is proposed to recognize the phonemes in each frame...
This paper presents a video shot boundary detection system based on support vector machine (SVM) classification method. A hardware fully-parallel digital support vector machine (SVM) classifier is used to detect the shot boundary in a continuous video stream. The throughput is increased by employing a pipelined architecture in the feature extraction stage. Hardware SVM can detect both cut and gradual...
This paper demonstrates the use of a single chip FPGA for the extraction of highly accurate background models in real time. The models are based on 24 bit RGB values and 8 bit grayscale intensity values. Three background models are presented, all using a camcorder, single FPGA chip, four blocks of RAM and a display unit. The architectures have been implemented and tested using a Panasonic NV-DS60B...
