Increasing urbanisation, wealth and ill health in cities necessitate careful study, especially in African cities whose development is widely regarded as rapid and chaotic. Using Ghanaian cities as a case study, this article ...

ILT - table light. Materials - acrylic and aluminium. The ILT light is the result of a research project into cold-forming acrylic sheet. Cold-forming is the ability to create form without the need for moulds or external ...

This paper presents a novel algorithm for computing graph edit distance (GED) in image categorization. This algorithm is purely structural, i.e., it needs only connectivity structure of the graph and does not draw on node ...

Spiral Architecture is a new and powerful approach to a general-purpose machine vision system. Earlier research on the Spiral Architecture focused on the properties of undistorted translation, rotation and scaling. The ...

This paper proposes a new method for natural-image deblur based on a single blurred image. The natural image prior, a sparse gradient distribution, is enforced using a gradient histogram remapping method in the proposed ...

Spiral Architecture is a relatively new and powerful approach to image processing. It contains very useful geometric and algebraic properties. Based on the abundant research achievements in the past decades, it is shown ...

This paper proposes a new image quality assessment framework which is based on color perceptual model. By analyzing the shortages of the existing image quality assessment methods and combining the color perceptual model, ...

Video-based facial expression recognition is a challenging problem in computer vision and human-computer interaction. To target this problem, texture features have been extracted and widely used, because they can capture ...
