FPGA IMPLEMENTATION OF A REALTIME CYCLOSTATIONARY FEATURE DETECTOR FOR OFDM SIGNALS
The demand for wireless connectivity has prompted regulatory authorities in the United States to investigate spectrum sharing of the DSRC band with U-NII operators. However, DSRC operation has public safety implications, and moreover, time-critical requirements due to the vehicular nature of its …

An Approach to Automatic Selection of the Optimal Local Feature Detector
Feature matching techniques have significantly contributed in making vision applications more reliable by solving the image correspondence problem. The feature matching process requires an effective feature detection stage capable of providing high quality interest points. The effort of the …

Feature guided pixel matching and segmentation in motion image sequences
The problem of feature correspondences and trajectory finding for a long image sequence has received considerable attention. In this research, a coarse-to-fine algorithm is developed to obtain pixel trajectories through the sequence and to segment them into subsets corresponding to objects moving …

Activity and Structure of Auditory Brain Neurons Underlying Phonotactic Behaviour in Female Crickets
… male calling song. A delay-line and coincidence detector circuit with five neurons underlying auditory pattern recognition in the bi-spotted cricket Gryllus bimaculatus was identified by Schöneich et al (2015). My results here confirmed the morphology of the five identified neurons. Moreover, the …

Real-Time Implementation of Vision Algorithm for Control, Stabilization, and Target Tracking for a Hovering Micro-UAV
… algorithm to detect, correlate, and track features in a scene and estimate attitude information was implemented with a combination of hardware and software on the FPGA, and real-time performance was obtained. The algorithms implemented include a Harris feature detector, template matching …

Preliminary investigation of the temporal specificity of sequence learning in the primary visual cortex through predictive coding
… (V1) has been classically viewed as an immutable feature detector, with robust responses to low-level characteristics of objects in the visual field. Recent studies have shown the capacity of this cortical area to perform more complex computations. Nominally, the phenomenon of sequence learning …

Spectrogram Track Detection: An Active Contour Algorithm
… spectrograms. An investigation into low-level feature detection reveals that none of the evaluated methods perform adequately within the low signal-to-noise ratios of real-life spectrograms and, therefore, two novel feature detectors are proposed. An investigation into the various sources of …

Adaptive vision based scene registration for outdoor augmented reality
Augmented Reality (AR) involves adding virtual content into real scenes. Scenes are viewed using a Head-Mounted Display or other display type. In order to place content into the user's view of a scene, the user's position and orientation relative to the scene, commonly referred to as their pose, …
