Pedestrian detection in low-resolution videos
… pedestrian detection is to use high resolution single frame, and there is relatively little work focused on pedestrian detection in low resolution scenarios. Under more realistic and challenging conditions, performance of the available approaches degrades rapidly, while approaches that are based …

Recognizing simple human actions by exploiting regularities in pose sequences
… based on human-pose classification from a single frame and from a model of transitions between poses through time. The system comprises three parts. The first part is the pose classifier that is capable of inferring a pose from a single frame. Its role is to take as input an image and give …

A low power display driver with simultaneous image transformation
… multiplication (image transformation) over a single frame period. This image transformation was used as the last step of the decompression process in an image processing system. The system was implemented first in Matlab, then as a printed circuit board, and finally as an integrated circuit. …

A Performance Comparison of Frame Structures in WiMAX Multi-Hop Relay Networks
… the potential to offer many advantages over the single-hop technology. Upcoming broadband wireless technologies, that utilize multi-hop relays, need good network planning and design in order to achieve their full potential. There are two main types of multi-hop relay stations: transparent, which …

Intelligent Rotoscoping: A Semi-Automated Interactive Boundary Tracking Approach to Video Segmentation
… extraction of an object from a series of video frames. However, it is a difficult problem, especially to compute at real-time, interactive rates. Although general application to video is difficult because of the wide range of image scenarios, user interaction can help to reduce the problem space …

Vehicle-pedestrian interaction using naturalistic driving video through tractography of relative positions and pedestrian pose estimation
… pedestrian body segments. Based on existing single-frame human pose estimation model, we have introduced Kalman filtering and temporal movement reduction techniques to make stable stick-figure videos of the pedestrian dynamic motion. We were able to reduce frame to frame pixel offset by 86% …

Human Activity Analysis
… prevalent, with higher resolution and frame-rates. Humans are often the focus of these videos, making human motion analysis an important field. This thesis explores the level of detail necessary to distinguish human activities for tasks of regression, like body tracking, and activity …

Generalized Probabilistic Bowling Distributions
… expected value and standard deviation of each frame's score, the expected value of the game’s final score, and the correlation coefficient between the score of the first and second roll of a single frame. Furthermore, we shall generalize the results in each distribution for an frame game on …

Unsupervised Learning for Generative Scene Editing and Motion
… in a generative context. Within this generative framework, we show that BlobGSN facilitates novel scene generation and editing. In a different vein, current state-of-the-art optical flow learning models rely on ground truth data collection for sequences of frames in videos. Unsupervised learning …

Development of an H-Alpha Index for the Detection of PMS Candidates in Young Open Clusters
… to obtain the entire region of interest in a single frame. Once tested to ensure the validity of the method, the wide-angle Hα wide/narrow procedure is applied to several young open clusters. The development of the index and the results of its application to the clusters are presented. Also, …

Open architecture framework for improved early stage submarine design
… through a design are no longer locked into a single frame of reference. The appropriateness of each decision is better understood within the context of the greater knowledge of submarine design. This flexibility in approach allows decision making such that the assumptions made during design …

Real-time highlight removal from a single image
… may require that methods work with a single frame in imaging or video streams. Thus, this work proposes a novel method for the real-time removal of specular highlights from a single image. The essence of the proposed method consists in matching the histogram of the luminance component …

Automating Video Analysis for Marine and Behavioural Research: Deep Learning Solutions to Analytical Bottlenecks
… (the maximum individuals observed in a single frame). The automated pipeline also enabled investigation of stereo-vision revealing that combining viewpoints from stereo-BRUVs increases sensitivity to experimental variables. Chapter 3 presents AnimalTrackR …

Structure and motion from long image sequences
… and instead of detecting the features in a single frame, the algorithm then detects the paths of the features as they move over several frames. To determine the structure and motion of the objects, the trajectories must be partitioned into groups corresponding to the different objects, and …

Applications of neutron radiography & tomography
… is capable of producing high quality images with single-frame exposure times down to the millisecond regime. Meanwhile, the modest beam divergence of 6 mrad (equivalent to a beam length-to-diameter ratio, LID, of -150) can achieve a spatial resolution in the region of 150-300 11m. It is …

Sketch-based skeleton-driven 2D animation and motion capture.
… the traditional way is drawing the key-frames by experienced animators manually. It is a laborious and time-consuming process. With the proposed techniques, the user only inputs one image ofa character and sketches a skeleton for each subsequent key-frame. The system then deforms the …
