Colour image difference analysis: quantitative versus qualitative methods
2001 IEEE International Conference on Systems, Man and Cybernetics. e-Systems and e-Man for Cybernetics in Cyberspace (Cat.No.01CH37236), 2002This paper describes investigation of statistical correlation between the results of two image colour difference criteria: qualitative and quantitative. The aim is that, provided there is consistently high correlation between the results of the different methods, the quantitative method, which is relatively more convenient, could be used instead of the

Segmentation and analysis of colour Doppler images of tumour vasculature
Ultrasound in Medicine & Biology, 1995A technique has been developed to segment (separate), from a digitized colour Doppler video image, the colour and greyscale information and then to estimate from the colour information the original mean Doppler frequency shift data from which the image was created. The remapped velocity image is then analysed to extract numerical features of the tumour

Colour Image Analysis in 3D-Polar Coordinates
2003The use of 3D-polar coordinate representations of the RGB colour space is widespread, although many of these representations, such as HLS and HSV, have deficiencies rendering them unsuitable for quantitative image analysis. Three prerequisites for 3D-polar coordinate colour spaces which do not suffer from these deficiencies are suggested, and the ...

Colour Model Analysis for Histopathology Image Processing
2013This chapter presents a comparative study among different colour models (RGB, HSI, CMYK, CIEL*a*b*, and HSD) applied to very large microscopic image analysis. Such analysis of different colour models is needed in order to carry out a successful detection and therefore a classification of different regions of interest (ROIs) within the image.

During ripening of salami, colour changes occur due to oxidation phenomena involving myoglobin. Moreover, shrinkage due to dehydration results in aspect modifications, mainly ascribable to fat aggregation. The aim of this work was the application of image analysis (IA) and multivariate image analysis (MIA) techniques to the study of colour and aspect ...

In this article, we propose a new colour image segmentation algorithm by unsupervised classification of pixels. This procedure iteratively constructs the classes by histogram multithresholding. For this purpose, the procedure selects different colour spaces in which the pixels belonging to the modes of the 1D-histograms present remarkable connectedness

Multiresolution colour texture analysis for classifying colon cancer images
Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002Co-occurrence matrices are commonly used to extract fine texture information from images, and have been found to be a useful tool for measuring dysplasia in histological images of the colon. Pathologists, however, measure dysplasia in tissue samples at structural as well as cytological levels.

Assessment of fire damaged concrete using colour image analysis
Construction and Building Materials, 2001Abstract Assessment of fire damaged concrete structures usually starts with visual observation of colour change, cracking and spalling. On heating, a change in colour from normal to a pink/red is often observed and this is useful since it coincides with the onset of significant loss of concrete strength.

QUANTIFICATION OF CARDIAC FIBROSIS BY COLOUR‐SUBTRACTIVE COMPUTER‐ASSISTED IMAGE ANALYSIS
Clinical and Experimental Pharmacology and Physiology, 20081. Quantification of fibrosis is a key parameter in the assessment of the severity of cardiovascular disease and efficacy of future candidate therapies. Computer-assisted methods are frequently used to assess cardiac fibrosis in several experimental models.

Analysis on Texture and Colour Based Features of Periocular for Low Resolution Colour Iris Images
2018 IEEE Conference on Systems, Process and Control (ICSPC), 2018The low resolution iris images in non-cooperative environment has resultant in failure to determine the eye center, limbic and pupillary boundary of the iris segmentation. Hence, a combination with periocular area is suggested to improve the accuracy of the recognition system.
