The performance of matching and object recognition methods based on interest points
depends on both the properties of the underlying interest points and the choice of …

A robust face detection technique along with mouth localization, processing every frame in
real time (video rate), is presented. Moreover, it is exploited for motion analysis onsite to …

A new software-based liveness detection approach using a novel fingerprint
parameterization based on quality related features is proposed. The system is tested on a …

Previous work has found strong links between the choice of social media images and users'
emotions, demographics and personality traits. In this study, we examine which attributes of …

A technique evaluating liveness in face image sequences is presented. To ensure the actual
presence of a live face in contrast to a photograph (playback attack), is a significant problem …

Three-dimensional imaging and image processing has become an important part for
investigations of fluid distribution and flow in porous media. We describe two methods of …

One of the open issues in fingerprint verification is the lack of robustness against image-
quality degradation. Poor-quality images result in spurious and missing features, thus …

Building activities are inadequately monitored during construction projects when attempting
to satisfy the need for information, especially in those cases of unforeseen events and …

Colour and texture are two perceptual stimuli that determine, to a great extent, the
appearance of objects, materials and scenes. The ability to process texture and colour is a …

A terrestrial laser scanner was used to take four scans of an area of trees, approximately 480
m2 in area, within a coniferous tree stand situated in Leicestershire, UK. A number of …
