In this paper we integrate colour, texture, and motion into a segmentation process. The segmentation consists of two steps, which both combine the given information: a pre-segmentation step based on nonlinear diffusion for improving the quality of the features, and a variational framework for vector-valued data using a level set approach and a statistical model to describe the interior and the ...

A fast and robust type of unsupervised multispectral texture segmentation method with unknown number of classes is presented. Single decorrelated monospectral texture factors are represented by four local autoregressive random field models recursively evaluated for each pixel and for each spectral band. The segmentation algorithm is based on the underlying Gaussian mixture model and starts with...

Results are presented of the effect of freezing followed by thawing (air and water immersion, both at environmental temperature) and cooking (traditional boiling in a covered pot) on quality profile (in terms of objective texture, colour, chlorophylls and pheophytins and sensory attributes) and structure of green beans (cv. Win). Freezing was carried out at three different rates by forced conve...

The project is concerned with the development of algorithms for the creation of photo-realistic 3D virtual environments, overcoming problems in mosaicing, colour and lighting changes, correspondence search speed and correspondence errors due to lack of surface texture. A number of related new algorithms have been investigated for image stitching, content based colour correction and efficient 3D...

A wide range of software tools have been developed for visualising three-dimensional range data of topographic surfaces. Digital Elevation Models (DEMs), derived from photogrammetric measurements and from digitised contour maps are here used for illustration. To increase our understanding of the information content in DEMs in isolation or in combination with remotelysensed images and to facilit...

Aloe Vera has gained more attention over the last decade due to its reputable, medicinal, and pharmaceutical and food properties. In present research, firstly the different concentrations of pectin and gum acacia were augmented with aloevera gel and the products so prepared were assessed for texture and stickiness. The selected preparation was then supplemented with orange flavour at different ...

Texture-mapping in close-range photogrammetry focuses mostly on the generation of large-scale projections of 3D surfaces, the most common instance being that of orthoimaging. Today, photogrammetry increasingly uses terrestrial laser scanning as basis for generation of 3D models. For a full exploitation of fully 3D data, however, typical shortcomings of conventional orthorectification software (...

In this paper, we propose an original approach for texture and colour segmentation based on the tensor processing of the nonlinear structure tensor. While the tensor structure is a well established tool for image segmentation, its advantages were only partly used because of the vector processing of that information. In this work, we use more appropriate definitions of tensor distance grounded i...

OBJECTIVE Whilst considerable progress has been made in enhancing the quality of indirect laryngoscopy and image processing, the evaluation of clinical findings is still based on the clinician's judgement. The aim of this paper was to examine the feasibility of an objective computer-based method for evaluating laryngeal disease. MATERIAL AND METHODS Digitally recorded images obtained by 90 de...

The objective of the present study was undertaken to standardize the levels of shredded potato and added water in the development of chevon cutlets. The lean meat was minced twice through 4 mm plate. The cutlets were prepared with the incorporation of shredded potato at 0, 5, 10 and 15% level and added water at 0, 3, 6 and 9%, respectively replacing the lean meat. A significant effect of mincin...
