Localization is an essential problem in autonomous navigation of self-driving cars. We present a monocular vision based approach for localization in urban environments using road markings. We utilize road markings as landmarks instead of traditional visual features (e.g. SIFT) to tackle the localization problem because road markings are more robust against changes in perspective, illumination, and...
Captions are a central component in image posts that communicate the background story behind photos. Captions can enhance the engagement with audiences and are therefore critical to campaigns or advertisement. Previous studies in image captioning either rely solely on image content or summarize multiple web documents related to image's location; both neglect users' activities. We propose business-aware...
Interest in the area of collaborative Unmanned Aerial Vehicles (UAVs) in a Multi-Agent System is growing to compliment the strengths and weaknesses of the human-machine relationship. To achieve effective management of multiple heterogeneous UAVs, the status model of the agents must be communicated to each other. This paper presents the effects on operator Cognitive Workload (CW), Situation Awareness...
The interest in utilising multiple heterogeneous Unmanned Aerial Vehicles (UAVs) in close proximity is growing rapidly. As such, many challenges are presented in the effective coordination and management of these UAVs; converting the current n-to-1 paradigm (n operators operating a single UAV) to the 1-to-n paradigm (one operator managing n UAVs). This paper introduces an Information Abstraction methodology...
The functionality of video surveillance is significantly degraded by the low illumination and poor visibility under the nighttime environment. However, the demand for nighttime surveillance is no less than the daytime one because of the high incidence of accidents during night. The Infrared (IR) light source with fixed intensity works for only certain distance, resulting in the defect of underexposure/overexposure...
Unlike human brains, where various kinds of visual recognition tasks are carried out with homogeneous neocortical circuits and a unified working mechanism, existing visual recognition processors [1–4] rely on multiple algorithms and heterogeneous multicore architectures to accomplish their narrowly predefined recognition tasks. In contrast, new brain-mimicking recognition algorithms have been proposed...
State-of-the-art object retrieval systems are mostly based on the bag-of-visual-words representation which encodes local appearance information of an image in a feature vector. A search is performed by comparing query object's feature vector with those for database images. However, a database image vector generally carries mixed information of an entire image which may contain multiple objects and...
High-definition multimedia interface (HDMI1.3) specifies video serial link that operates from as low as 250 Mb/s to 3.4 Gb/s with coverage over different multimedia data formats. Wide-spread consumer adoption of the new HDMI standard demands receivers that reliably reproduce the incoming data stream under conditions of either short/long cables or clear/fuzzy signal. In many cases, input video signal...
