A baby boy born by vacuum extraction at gestation of 36 weeks had a birth weight of 2.84 kg. After 2 days of life he developed respiratory distress and poor skin perfusion, whereupon he was transferred to the neonatal intensive care unit (NICU) in December 2011. Cerebrospinal fluid culture (CSF) grew Streptococcus bovis type 2 i and meningitis was diagnosed. He had an episode of generalised ton...

The paper proposes a novel change-detection algorithm for automated videosurveillance applications. The algorithm is based on the idea of incorporating into the background model a set of simple low-level features capable of capturing effectively “structural” (i.e. robust with respect to illumination variations) information. Thanks to this approach, and unlike most conventional change-detection ...

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

Organisms capable of rapid physiological colour change have become model taxa in the study of camouflage because they are able to respond dynamically to the changes in their visual environment. Here, we briefly review the ways in which studies of colour changing organisms have contributed to our understanding of camouflage and highlight some unique opportunities they present. First, from a prox...

Foreground detection has been used extensively in many applications such as people counting, traffic monitoring and face recognition. However, most of the existing detectors can only work under limited conditions. This happens because of the inability of the detector to distinguish foreground and background pixels, especially in complex situations. Our aim is to improve the robustness of foregr...

Animals change their body coloration for a variety of purposes including communication, thermoregulation and crypsis. The cues that trigger adaptive colour change are often unclear, and the role of colour vision remains largely untested. Here, we investigated the bluestriped fangblenny (Plagiotremus rhinorhynchos), an aggressive mimic that changes its body coloration to impersonate a variety of...

A new test of colour vision using computer graphics has been used to obtain quantitative estimates of colour contrast sensitivity in ophthalmologists before and after they have treated patients by argon laser retinal photocoagulation. The colour vision of all subjects is normal when tested with the 100-hue test and HRR (Hardy, Rittler, Rand) plates, but colour contrast sensitivity measured alon...

This thesis aims to find out the usage of colour in the game called Journey (2012). It is a case study which focuses on three different scenes in the game and how their colour scheme affects the game both emotionally and the storyline progress. The question that will be answered is: How does the choice of colour affect the players perception on an emotional level? This thesis talks about how di...

This paper presents the first direct demonstration in a living cephalopod of neural activity associated with chromatic behaviour. It has long been known that colour change in these molluscs is unique in that it is brought about by chromatophores controlled neurally rather than hormonally (e.g. Hofmann, 1907). The chromatophore muscles are innervated directly by nerves whose cell bodies lie in t...

The heat treatment of softwood (i.e. spruce, pine, fir, and larch) may result in significant colour changes. During this study Scots pine and spruce samples were steamed and analysed for their altered hue and lightness. Treatments included: 0 to 22 days of steaming time at a temperature range of 70 to 100°C. The outcome included a variety of colours between the initial hues and brownish tint. T...
