A surface roughness measurement technique, based on an optical method using a computer vision system, was investigated for applicability to inprocess monitoring of surface quality. The developed vision system uses a CCD camera for scanning gray-scale images from an area of the machined workpiece. This images were analysed with digital image processing system. Some new optical roughness paramete...

We present 3D optical topography images reconstructed from data obtained previously while infants observed videos of adults making natural movements of their eyes and hands. The optical topography probe was placed over the temporal cortex, which in adults is responsible for cognitive processing of similar stimuli. Increases in oxyhaemoglobin were measured and reconstructed using a multispectral...

A direct method for the measurement of the optical attenuation coefficient and the scattering anisotropy parameter based on applying the extended Huygens-Fresnel principle to optical coherence tomography images of blood is demonstrated. The images are acquired with a low-power probing beam at the wavelength of 1300 nm. Values of 12.15 mm(-1) and 0.95 are found for the total attenuation coeffici...

The interest on acquiring player and ball data during soccer games is increasing in several domains such as media or training. Consequently, tracking systems are becoming widely used for live data gathering. However, due to costs, stadium infrastructure, media rights etc. there is a trend for stand-alone mobile low-cost soccer tracking systems. The drawback of such systems is that generally onl...

Black-white and colour skin/lesion images are synthesised with known characteristics such as boundary, skin pattern and colour. The skin and lesion textures are modelled by the auto-regressive (AR) process. Black-white skin lesion images are obtained by combining black-white skin and lesion textures under control of known lesion shape and colour skin lesion images are generated by mixing the co...

In this paper we describe an approach to automatically estimate movements of vehicles in optical satellite imagery. The approach takes advantage of the fact that the optical axes of the panchromatic and multispectral channels of current spaceborne systems like IKONOS or Quickbird are not coinciding. The time gap that appears between the acquisition of the panchromatic and multispectral data can...

Segmentation of the text from badly degraded document images is very challenging tasks due to the high inter/intra variation between the document background and the foreground text of different types of document images. In this paper, a novel document image binarization technique is used to addresses the issues in the degraded document images by using adaptive image contrast. The adaptive image...

Optical endomicroscopy (OEM) is an emerging technology platform with preclinical and clinical imaging utility. Pulmonary OEM via multicore fibres has the potential to provide in vivo in situ molecular signatures of disease such as infection and inflammation. However, enhancing the quality of data acquired by this technique for better visualization and subsequent analysis remains a challenging p...
