Efficient Ordinary Differential Equation Solver Using Stochastic Circuitry

Description
Ordinary differential equations are widely used in the modeling of natural processes in physics, chemistry, biology, engineering and social studies. Solving problems for a large scale system with conventional digital circuits are generally computationally intensive and slow. Conversely, the use of parallel computations in GPUs have accelerated computation speed at the cost of power consumption. […]

Time Efficient Scientific Visualization Tool

Description
While mathematical computation engines have built-in scientific visualization and animation capabilities, it is possible to achieve much more with the underlying data than what is currently realized. On the other hand, there are dedicated tools that can render high quality visualizations and animations. However, using those tools, it is often time consuming or very difficult […]

New Method for Single-Camera 3D Underwater Image Reconstruction

Description

Computer vision has become a popular method to explore the underwater environment. Underwater cameras are used for scientific exploration seafloor structure, monitoring undersea habitats, and inspecting industrial equipment. Camera calibration is required for recovering 3D geometry of a scene using 2D images. Despite the remarkable success for land-based camera systems, underwater camera calibration problems such as image distortion and […]

3D Reconstruction of Transparent and Reflective Objects

Description
3D object reconstruction is widely used in a number of industries to create a three dimensional digital model of a physical object.  Traditional acquisition systems rely on the expected light reflecting patterns off an object which can cause poor reconstruction when the object is transparent, reflective or refractive.  Researchers at the University of Alberta have […]

Highly Accurate, Automated People Counting Algorithm for Video Analytics

Description
Counting a person only once while the person passes through the field of view (FOV) is required in many video analytic applications such as keeping track of transit passenger numbers in railway stations, pedestrian volume monitoring in road intersections and malls, aiding in security, resource management and urban planning. The principle roadblock in most of the video analytic techniques […]

Novel Small-Area Low-Power Analog to Digital Converter for In-Pixel Data Conversion

Description
Most image sensors incorporate one analog-to-digital converter (ADC) per pixel array, or per column, to process a photodiode’s sensitive signal. The next generation of products aims to incorporate one ADC per pixel, which can result in higher contrast range and resolution, as well as sensitivity. The main challenge in pixel-level data conversion is producing a […]

Automated, objective feature selection for chemometric modeling

Description
Modern analytical techniques, including gas chromatography-mass spectrometry (GC-MS), infra red spectroscopy (IR) and two-dimensional gas chromatography (GCxGC), can provide an abundance of detailed data pertaining to the nature of complex samples. Chemometric models can then extract underlying patterns and translate the abundance of data into more useful information. However, when constructing chemometric models, one main […]
