Mental Rotation: Can Familiarity Alleviate the Effects of Complex Backgrounds?
<p>This dissertation investigated the effects of complex backgrounds on mental rotation. Stimulus familiarity and background familiarity were manipulated. It systematically explored how familiarizing participants to objects and complex backgrounds affects their performance on a mental rotation task …

Computational Approaches to Detect Pathogens in the Presence of Complex Backgrounds
… identification of pathogenic microorganisms in complex clinical and environmental samples is essential for the prevention and treatment of infectious diseases. The most sensitive and accurate detection approaches are based on the examination of the nucleic acid composition of the sample in order …

Change of Condition: Women's Rhetorical Strategies on Marriage, 1710-1756
… into the 1750s. They often elide their own complex backgrounds in favor of generalized policy statements on what constitutes a good marriage. These women promote an ideal of marriage based on respect and similarity of character, suggesting that friendship is more honest, and durable than …

Object tracking and fetal signal monitoring
… on detecting and tracking small objects in complex backgrounds and on classifying ultra-sound fetal movement signals. The first part of this dissertation focuses on detecting and tracking laser spots which are small objects in a video frames. Many factors make this particular problem …

Experiments in Image Segmentation for Automatic US License Plate Recognition
… absence of standardization and multi-colored, complex backgrounds are becoming more frequent in license plates. Commercially available optical character recognition (OCR) systems generally fail when confronted with textured or poorly contrasted backgrounds, therefore creating the need for …

Role of F0 in speech reception in the presence of interference : simulating aspects of cochlear-implant processing
… especially pronounced in understanding speech in complex auditory environments. For normal-hearing listeners, voice pitch or the fundamental frequency (FO) of voicing has long been thought to play an important role in the perceptual segregation of speech sources. The aim of this dissertation was …

New methods to improve detection and classification on waterfowl and tree in aerial images
… developed to improve detection performance in complex backgrounds by reducing false positives. SRN employs a novel sampling mechanism that ensures a balanced ratio of positive and negative proposals in each training batch and prioritizes challenging cases, achieving a 10.1 percent improvement …

The function of passive debris cloaking in tiny beetles (Coleoptera: Zopheridae)
… Additionally, I found that texturally complex backgrounds reduce detection of stationary zopherid beetles even when background colour matching is poor. I also found camouflage isn’t broken during movement to a jumping spider predator, but instead provides prey with additional time to …

A study on the effect of target object size in object detection
… struggle to distinguish between foreground and complex backgrounds such as rough terrain. An experiment was designed to investigate a selection of deep neural networks and analyse the effects that the distance between the capturing device and the target object. The set up requires a custom …

Content-based indexing of low resolution documents
… environment’s varying lighting conditions and complex backgrounds. We present hierarchy indexing techniques, whose foundation are tree and clustering. K-means clustering are used for visual features like colour since their spatial distribution give a good image’s global information. Tree …
