drug recognition experts(DRE) are certified officers that are trained to determine if drugs are present in the body and if the substance that they have taken impaired them in any way during an incident or altercation. While police and other public service officers are able to perform some tests for alcohol and drug levels. the DRE program investigates whether drugs were involved and what effects they may have caused physically or mentally. By way of the 12 steps of the Drug Recognition Process. Some

Face recognition study: Inverted V Upright faces. Introduction: Face recognition is a difficult visual representation task in large part because it requires differentiating among objects which vary only subtly from each other. This particular face recognition study was expected to suggest that people recognise inverted faces less accurately than upright faces. The study involved sixty different faces observed on a computer screen by a sample of first-year university students. Hypothesis:

2.7 Various Methods for Face Recognition: There are various types of face detection algorithms have been developed. Most of the face detection methods take pixel values as features. But they are highly delicate to lighting variations and noises. Face recognition is the task of identifying an already detected face as a known or unknown face. 2.7.1 PCA: In this method convert the image training set to image vector. Image vector is used for finding eigen feature weight matrix. Eigen feature can

problem solve‚ reflect on and evaluate results‚ and modify one’s approach as needed. It helps learners choose the right cognitive tool for the task and plays a critical role in successful learning. What Is Metacognition? Metacognition refers to awareness of one’s own knowledge: what one does and doesn’t know; and one’s ability to understand‚ control‚ and manipulate one’s cognitive processes (Meichenbaum‚ 1985). It includes knowing when and where to use particular strategies for learning and problem

%FACE RECOGNITION SYSTEM % % Face recognition system based on EigenFaces Method. % The system functions by projecting face images onto a feature space % that spans the significant variations among known face images. The % significant features are known as "eigenfaces" because they are the % eigenvectors (principal components) of the set of faces. % % Face images must be collected into sets: every set (called "class") should % include a number of images for each person‚ with some variations

An Independent Evaluation of Subspace Face Recognition Algorithms Dhiresh R. Surajpal and Tshilidzi Marwala Abstract— This paper explores a comparative study of both the linear and kernel implementations of three of the most popular Appearance-based Face Recognition projection classes‚ these being the methodologies of Principal Component Analysis (PCA)‚ Linear Discriminant Analysis (LDA) and Independent Component Analysis (ICA). The experimental procedure provides a platform of equal working conditions

Evaluate/Compare and Contrast/Discuss/Examine models or theories of one cognitive process with reference to research studies (22) Human beings actively process information and it is cognitive processes that guide behavior. These cognitive processes are influenced by social and cultural factors. One of the cognitive processes is memory. Many researchers and psychologies have proved that the mind can be studies scientifically by developing theories and using a number of scientific research methods

The face recognition model developed by Bruce and Young has eight key parts and it suggests how we process familiar and unfamiliar faces‚ including facial expressions. The diagram below shows how these parts are interconnected. Structural encoding is where facial features and expressions are encoded. This information is translated at the same time‚ down two different pathways‚ to various units. One being expression analysis‚ where the emotional state of the person is shown by facial features. By
