Palm-dorsa vein image enhancement algorithm using webcam for biometric system

AIP Conference Proceedings 2019年第1期2129卷

作者： Suhaimi Yusoff Abdul Rahman Ramli Izanoordina Ahmad Zulhilmi Mustafa 1Electronics Technology Department Universiti Kuala Lumpur British Malaysian Institute Malaysia 2Department of Computer and Communication System Engineering Universiti Putra Malaysia Malaysia

In this article, an algorithm for palm-dorsa vein image enhancement is proposed. Instead of using expensive high-quality vein image capture device, a low-cost webcam was used to capture the vein image. The webcam has been modified to make it possible to capture the vein image of palm-dorsa. In this research, the algorithm to enhance the low-quality vein image, remove the noise and finally detect the palm-dorsa vein pattern has been developed. First, the vein image is applied with image normalization technique to obtain standard image. Then, the Gaussian filter is used to remove the noise in the vein image. Next, Difference of Gaussian and threshold techniques are used to segment the vein image. Median filter is used to remove and smooth the noise introduced from the previous image segmentation process. Finally, thinning technique is used to get single line palm-dorsa vein pattern. Even though the vein images from webcam are noisy and very low contrast, results show that the proposed algorithm still can get good vein image enhancement.

The need for surveillance in a society escalates with an increase in population. As more people reside in a specified area, monitoring their activity gets tougher, which gives a rise in security concerns. Not only in societies, the need for surveillance, monitoring and detection has been a prime requirement in the defence sector. This research aims in developing a surveillance and detection robot which would be capable of various applications like monitoring environment at greater distances, detecting obstacles and objects, detecting mines in the ground and achieving autonomy in traversal. All these features combined in one package will serve as a complete solution to this problem. This robot can be used for surveillance, sending live feed to a local ground station in the city. Moreover, this robot can be used in hostile situations with the armed forces. The bot can be sent to survey a particular area and provide necessary data back to the soldiers to determine safety in proceeding further. Components ranging from cameras, motors, microcontrollers, sensors, communication modules are present in the system. The robot is an integration of various subsystems working together to provide an optimum solution for surveillance and detection.

Mridula Ishan Kar Kritika Raj 1Department of Electrical and Electronics Engineering SRM Institute of Science and Technology Kattankulathur-603203 Tamilnadu India 2Department of Computer Science Engineering SRM Institute of Science and Technology Kattankulathur-603203 Tamilnadu India

The assiduous irregularity of heart beat rate might be a omen of some stern health related issues such like Tachycardia, coronary and Artery infirmity. Therefore it is acutely crucial to keep groove of one’s health by auditing the rate of heart beat. As some customary approach like Electro-cardiogram (ECG) are already in use, but the usage is too convoluted and cumbersome. This demand for unique facile and modest heart rate scaling apparatus. This paper delineates the layout and operation of the equipment stationed on the fundamentals of Pulse Oximeter. This apparatus is prudent, user-friendly and low arduous device. The pursuance of the device was appraised and the outputs are correlated with the record of regular heart rate auditor by which the breach detected is minimum. The heart rate monitoring system uses a LM324 IC for the filtration and amplification of the signal which is to be processed further to get the output. The optical sensor consists of an IR Transmitter and a Photo Detector which is placed over the finger to measure the counting of the pulse. This low cost device is interfaced with Arduino which programs the device to display the heart rate. After the above system is allied to computer, there is a gratification to the user, they would be able to examine the condition of pulse rates. Besides the above mentioned features, the waveforms attained can be used for advertence in future. This would help the user to figure out and shot their heart pulse rate at home.

Synchronization dynamics and numerical simulation of three coupled oscillators through extended Poincaré-Cartan invariants

引用

AIP Conference Proceedings 2019年第1期2061卷

作者： Pranjal Rastogi Vikas Rastogi 1Department of Computer Science Jaypee Institute of Information Technology Noida U. P. India 2Department of Mechanical Engineering Delhi Technological University Delhi India

This article presents the numerical simulation of three linearly coupled oscillators, which are connected to form the circadian rhythms for analysing the motion of eyes. In this system of circadian rhythms, each eye is modeled as van der Pol oscillators and both such oscillators are not directly interconnected but connected through another similar oscillator. This oscillator models the pineal gland, which is responsible for linkage with brain muscles. The van der Pol oscillators are coupled with such couplings, where non-linear damping parameters are also included in this system. The dynamics is determined analytically through a novel approach of extended Poincaré-Cartan Invariants of Lagrangian theory, which demonstrates the invariance of Poincare integral in three-dimensional phase space. The synchronization dynamics is achieved with in-phase and out of phase motions of oscillators with varying parameters. In this analysis, the effect of injected signal is also analyzed by adding some detuning parameter considering the associated boundaries of the stable synchronized states. This analysis is corroborated with simulation results to visualize the dynamical behaviour.

A large number of individuals are languid in regard to workouts. They are reluctant to go out for biking. This venture gives a virtual situation to them while they do practice on indoor machines. A viable alternative to these methods of transport that can be alluring to a wide crowd, for transport in a versatile range of environments in a protected space for exercises in cycling. This virtual space is created with Unity, a real-time cross-platform game engine which supports Virtual Reality (VR) technology. The clients can have a rich and immersive interaction with the system. The sensor attached to the stationary bicycle sends signals to the client’s cell phone by means of Bluetooth which controls the virtual vehicle on the gadget. The motion from the paddle and steering movement is tallied as the speed and direction of the virtual automobile. Low energy Bluetooth, potentiometers, gyro-sensor, reed switch, and accelerometer were used as components to make the system to achieve the mentioned tasks. The uniqueness of this innovation lies in the coherence of the system which allows the costumer to implement in almost in any paddle powered vehicle in a user-friendly manner with economic feasibility.

Head in 1987 was the first person to introduce the concept of splicing system as a theoretical model for DNA based computation using splicing operation. Splicing operation is a method of cutting and recombining DNA molecules under the influence of restriction enzymes such as ligase. Previous researches have proven that splicing systems with finite sets of axioms and rules generate only regular languages. Hence, in order to increase the computational power of the languages generated by splicing systems, several restrictions in the use of rules have been considered. In this paper, simple splicing systems controlled by permutation groups are defined and the computational power of the languages generated by this variable is explored.
