Deoxyribonucleic Acid or DNA computing has emerged as an interdisciplinary field that draws together chemistry, molecular biology, computer science, and mathematics. From the DNA computing point of view, it has been proven that it is possible to solve weighted graph problems by exploiting some characteristics of DNA such as length, concentration, and(More)
This paper presents the implementation of moment invariants; with respect to centroid point obtained from frontal mugshot images, for thermal-based face identification system. Initially, seeded region growing method is applied for background filtering. Sequentially, the system decomposes a background filtered thermal image into 4 thermal regions via(More)
We present a design and implementation method to solve an elevator scheduling problem using DNA computing in this research. DNA sequences of length directly proportional to the elevator’s traveling time are encoded to represent all possible travel path combinations based on certain initial conditions such as present and destination floors, and hall calls(More)
A new readout approach for the Hamiltonian Path Problem (HPP) in DNA computing based on the real-time polymerase chain reaction (PCR) is investigated. Several types of fluorescent probes and detection mechanisms are currently employed in real-time PCR, including SYBR Green, molecular beacons, and hybridization probes. In this study, real-time amplification(More)
Image difference operation is frequently used in automated printed circuit board (PCB) inspection system as well as in many other image processing applications. The previously proposed wavelet-based PCB inspection approach also incorporated the point-to-point image difference operation as part of its algorithm. Unfortunately, during the implementation, this(More)
DNA computing has a lot of potential, in terms of ability to implement a relational database with circular molecules. In this work, a new DNA-based semantic model is proposed and described theoretically for implementing DNA based memories. This model, referred to as ‘semantic model based on molecular computing’ (SMC), has the structure of a graph formed by(More)
Problem statement: Current paramount methods and approaches in face identification field rely on facial characteristics; such as location of eyes, length of nose and mouth, regardless the type of medium used to acquire the facial images. The visibility of these facial characteristics varies significantly with environmental factors (e.g., lighting elements).(More)
Compared to physiologically based biometric systems such as fingerprint, face, palm-vein and retina, behavioral based biometric systems such as signature, voice, gait, etc. are less popular and many are still in their infancy. A major problem is due to inconsistencies in human behavior which require more robust algorithms in their developments. In this(More)
