Face Recognition and Expression Recognition using Morphable Models
… VARIATIONS, IS USED TO PERFORM FACE IDENTITY RECOGNITION. TO ACCOUNT FOR EXPRESSION-RELATED INTRA-FACE VARIATIONS, INTRA-FACE-MODEL (INTRA-FACE) IS CREATED USING EXPRESSIVE FACES FOR EVERY SUBJECT IN THE DATABASE. WITH THE USE OF THE INTER-FACE AND INTRA-FACE MODEL, WE SHOW THAT A SUCCESS RATE …

Dynamic gesture recognition using transformation invariant hand shape recognition
… is presented for accurate real time gesture recognition. Our approach to develop a hand-shape classifier, trained using computer animation, along with its application in dynamic gesture recognition is described. The system developed operates in real time and provides accurate gesture …

Image recognition using the Eigenpicture Technique (with specific applications in face recognition and optical character recognition)
In the first part of this dissertation, we present a detailed description of the eigenface technique first proposed by Sirovich and Kirby and subsequently developed by several groups, most notably the Media Lab at MIT. Other significant contributions have been made by Rockefeller University, whose …

Recognition of aerospace acoustic sources using advanced pattern recognition techniques
An acoustic pattern recognition system has been developed to identify aerospace acoustic sources. The system is capable of classifying five different types of air and ground sources: jets, propeller planes, helicopters, trains, and wind turbines. The system consists of one microphone for data …

Recognition without recollection
… perceptually impoverished conditions, and b) recognition of the words as having been previously presented. In Experiment 1, distributing a two-second study duration between two one-second or four-second presentations as opposed to concentrating it into a single two-second presentation was …

Optical Graph Recognition
… In this thesis we introduce Optical Graph Recognition. Optical Graph Recognition (OGR) reverses Graph Drawing and transforms a digital image of a graph into an abstract representation. Our approach consists of four phases: Preprocessing where we determine which pixels of an image are part …

Handgrip pattern recognition
… fired by the authorized user. Handgrip pattern recognition holds great promise in the development of the smart gun. Two algorithms, static analysis algorithm and dynamic analysis algorithm, were developed to find the patterns of a person about how to grasp a handgun. The static analysis …

Road sign recognition
A method for recognizing road signs in street scene images is proposed. We first developed a fast region growing segmentation method, combined with a 1NN smoothing filter, to work on color and produce robust segmentation results even when the image is noisy. An effective color distance measurement …

Computer Sketch Recognition
… demonstrate that the accuracy of existing sketch recognition techniques can be improved by optimizing the classification criteria. Current techniques classify a 20,000 sketch crowd-sourced dataset with 56% accuracy. I classify the same dataset with 52% accuracy, but identify factors that have the …

Ship target recognition
… the low resolution non-cooperative ship target recognition problem. Three very different neural architectures are investigated and compared, namely; the Feedforward Network with Back-propagation, Kohonen's Supervised Learning Vector Quantization Network, and Simpson's Fuzzy Min-Max neural …

Polyhedra:representation and recognition
… useful in geometric modelling and machine recognition. We prove that the representation uniquely represents genus 0 polyhedra. We show by,example that our representation is not a strict dual of the vertex connectivity graph, and hence is not necessarily ambiguous. However, we have not been …

Automatic Dialect and Accent Recognition and its Application to Speech Recognition
… can be employed to improve Automatic Speech Recognition (ASR). In this thesis, we describe a variety of approaches that make use of multiple streams of information in the acoustic signal to build a system that recognizes the regional dialect and accent of a speaker. In particular, we examine …

Adaptive traffic sign recognition
… this thesis an automated video based speed limit recognition system is introduced together with the framework for adaptation of the system to the special characteristics of the signs in different countries. The system is to be used as a vehicle mounted driver assistance system. Autonomous …

Unconstrained Road Sign Recognition
… and pedestrians. Existent image-based road sign recognition systems work well under ideal conditions, but experience problems when the lighting conditions are poor or the signs are partially occluded. The aim of this research is to propose techniques to recognize road signs in a real outdoor …

Text-independent speaker recognition
… research presents new text-independent speaker recognition system with multivariate tools such as Principal Component Analysis (PCA) and Independent Component Analysis (ICA) embedded into the recognition system after the feature extraction step. The proposed approach evaluates the performance of …

Towards unconstrained ear recognition
… to impose constraints to achieve satisfactory recognition rates. These include limitations on the background of the image in which a feature is located, the lighting on the feature, its degree of occlusion, its viewed angle, and the properties of the camera that captures it. The computational …
