The progress in the field of affective computing enables the realisation of affective art. This paper describes the affective interactive art system Mood Swings, which interprets and visualises affect expressed by a person. Mood Swings is founded on the integration of a framework for affective movements and a colour model. This enables Mood Swings to recognise affective movement characteristics...

The design and development of a versatile active illumination system is described. The necessary system components are related to existing techniques which utilise various forms of structured light to extract range data. The system is composed of a high power stroboscopic illuminator coupled with a high resolution liquid crystal display and a precision actuated mirror. A colour filtering device...

Light Blue Optics’ holographic laser projection technology is uniquely suited as a light engine for automotive head-up display (HUD) applications, providing high brightness images with low speckle contrast and wide colour gamut whilst being robust and fault-tolerant. This paper describes the operation of the technology and its advantages, demonstrating – for the first time – the operation of a ...

Using a novel stimulator that incorporates a liquid crystal display, the spectral modulation sensitivity function of the colour vision system was derived by measuring discrimination thresholds for comb-filtered spectra. This function shows a peak of sensitivity at 0.97 c/300 nm with a plateau that extends to 1.67 c/300 nm. Extrapolation of the curve gives an estimated high-frequency cut-off at ...

Music is associated to colors since ancient years. Different mappings between attributes of sound and images allow the efficient conversion between the two types of media. The proposed method for converting images to music using the concept of chromaticism provides the area of computer music with a parameterized environment for audio-visual presentations. The auditory display of colour images m...

A real time visualisation method, to be used in mobile gamma-spectrometric search operations using standard detector systems is presented. The new method, called deviation display, uses a modified waterfall display to present relative changes in spectral data over energy and time. Using unshielded (137)Cs and (241)Am point sources and different natural background environments, the behaviour of ...

This paper defines one of the many ways to setup a soft proofing workstation comprising of a monitor display and viewing booth in a printing workflow as per the Function 4 requirements of PSO certification. Soft proofing requirements defined by ISO 12646 are explained and are implemented in this paper. Nec SpectraView LCD2180WG LED display along with Just colorCommunicator 2 viewing booth and X...

We propose a method for image enhancement in colour word when a scattering environment reduces the vision. The main advantage of blind technique is that it does not require any a priori information about the scattering environment but supposes that the observed signals are linear mixtures of sources. Here, the natural logarithm of the degraded image provides an approximative additive mixture of...

In a Cayley digraph on a group G, if a distinct colour is assigned to each arc-orbit under the left-regular action of G, it is not hard to show that the elements of the left-regular action of G are the only digraph automorphisms that preserve this colouring. In this paper, we show that the equivalent statement is not true in the most straightforward generalisation to G-vertex-transitive digraph...
