Towards Object-based SLAM
… two decades from the original sparse landmark-based SLAM to dense SLAM, and now there is a demand for semantic understanding of the environment beyond pure geometric understanding. This thesis delves into object-based SLAM where the map consists of a set of objects with their semantic …

An object-based codesign methodology.
… with the existing codesign methodologies. A new object-based codesign approach (Co-PARSE) is thus developed in this project, which is supported by successive phases, guidelines, and techniques. This methodology offers a coherent design framework for real-time embedded systems and incorporates the …

Flexibility in object-based selection
… is that attention tends to operate in an object-based manner (i.e., all features of attended objects, including task-irrelevant ones, tend to be co-selected, e.g., O’Craven et al.). However, recent evidence suggests that object-based attention is not always obligatory; people can be pushed …

Towards Active Object-Based Navigation
… the design and implementation of an active object-based navigation system. Localization refers to the capability of a mobile robot to determine its position relative to a prior map of the environment. Localization based on fiducial markers, such as AprilTags, has been a popular technique …

Open-Set Object Based Data Association
Representing the world using sparse objects allows for compact and semantically meaningful maps in simultaneous localization and mapping (SLAM). Traditionally, object detectors trained on a specific set of objects, such as the YCB objects, are used to provide input to the data association problem, …

"Object Based Attention in Visual Word Processing"
… on whether words are treated like visual objects by the human attentional system. Previous research has shown an attentional phenomenon that is associated specifically with objects: this is known as “object based attention” (e.g. Egly, Driver & Rafal, 1994). This is where drawing a …

Object-based audio capture : separating acoustically-mixed sounds
… and isolate individual sound sources, or audio objects, from an environment containing several sounds. The main contribution of this work is the application of object-based audio capture to unconstrained real-world environments. Several potential applications for object-based audio capture are …

Scalable Data Management for Object-based Storage Systems
… distributed storage systems, in particular the object-based storage systems, face severe challenges for managing the data efficiently. Inefficient data management leads to poor I/O and storage performance in HPC applications and scientific workflows. Some of the main challenges for efficient …

Object-based radio : effects on production and audience experience
This thesis analyses the benefits of using object-based audio as a production and delivery format in order to enable new audience experiences. This is achieved though a series of case studies, each focusing on a different user experience enabled by the use of object-based audio. Each study …

Performance analysis of object-based and message-driven programs
… for one such paradigm called Charm, a portable, object-based, and message-driven parallel programming language. In this thesis, we describe the process of design and implementation of this framework, and show its utility with sample case studies.

Concurrent checkpointing for fast recovery in object-based systems
Traditional checkpoint and recovery are based upon two basic assumptions. The first is the need to halt the computation in progress to save the state of the computation, i.e., take the checkpoint. The second assumption is that the entire state needs to be saved. These assumptions introduce fixed …

Long-term Object-based SLAM in Low-dynamic Environments
… advanced robotic tasks, engaging in consistent object-level reasoning is critical, especially for activities involving repetitive traversal within the same environment, such as household cleaning and object retrieval. In a changing world, robots should always locate themselves and their targets …

Addressing Challenges in Object-Based Robot Navigation and Mapping
… with the environment has been a long-term objective in robotics. Many relevant tasks, such as planning and mobile manipulation, require the robot to possess an object-level understanding of the ambient world. In particular, it would be crucial to maintain a globally consistent objectbased …

Object-based image analysis for detecting landforms diagnostic of natural hazards
… these processes in the first place, partly based on the diagnostic landforms that they form. To perform this effectively, automatic methods are desirable. Universal detection of natural hazards is challenging due to their differences in spatial impacts, timing and longevity of consequences, …

An object-based image analysis approach for detecting urban impervious surfaces
… from high spatial resolution imagery with pixel-based techniques have proven to be unsuitable for automated classification because of its high spectral variability and complex land covers in urban areas. Accurate and rapid classification of impervious surfaces would help in emergency management …

Instructional Video Object-Based Learning in a Flipped Construction Management Classroom
… traditional teaching models. One of these is object-based learning (OBL), a student-centered approach that uses digital learning objects (LOs), such as videos, images, animations, mobile apps, and educational games, to facilitate deep and engaging learning experiences. One of the most common …

Object-Based Coastal Morphological Change Analysis Based on LiDAR and Hurricane Events
… The purpose of this study is to apply an object-based approach using repeated LiDAR surveys to understand the short-term morphological changes that occurred on Santa Rosa Island, Florida after category 3 hurricanes Ivan (2004) and Dennis (2005), making it the first study to apply this …

Runtime support for object-based message-driven parallel applications on heterogeneous clusters
In the last several years, there has been a growing interest in utilizing accelerator technologies within the realm of high performance computing (HPC). Some of these technologies include the Cell processor (Cell), graphics processing units (GPUs), many integrated core (MIC), the single chip cloud …
