Luminance, colour and/or texture features may be used, either alone or in combination, for segmentation. In this paper luminance and colour classes are described using the corresponding empirical probability distributions. For texture analysis and characterisation a multichannel scale/orientation decomposition is performed using Wavelet Frame Analysis. Knowing only the number of the di erent cl...

The aim of this study is to provide an efficient way to segment the skin cancer images. A novel method is proposed that combines colour and texture for the segmentation of skin lesions from unaffected skin region in an image. The distributions of colour and texture features provide a good discrimination of skin lesions. The evaluation of the proposed method was based on the comparison with the ...

Image segmentation is one of the analytical processes for digital image recognition, where this process divides into several unique regions based on homogeneous pixels. The grouping images colour, texture and shape features. Colour in processing very important because colour has many information humans can easily understand. various features, combining intensity grey (grayscale) binary (black w...

A key problem for handling multimedia data in the semantic web is finding a way to associate concepts from ontologies to multimedia data items at an acceptable cost. This paper describes experiments with a system to assign automatically keyword metadata descriptors to unlabelled images. Learning to automatically match low level image features, like colour or texture to high level concepts (the ...

Most investigations of object recognition have focused on the form rather than the material properties of objects. Nevertheless, knowledge of the material properties of an object (via its surface cues) can provide important information about that object's identity. In this study, we used Garner's speeded-classification task to explore whether or not the processing of form and the processing of ...

Consumers believe that quality of foods from organic production is superior to foods from conventional production. The objectives of the present study have therefore been to compare the quality of chicken meat from organic and conventional production on the basis of traditional meat quality criteria. The experiment was organized as a field study. Fresh organic broiler carcasses were purchased d...

The paper presents an approach for projective texture mapping from photographs onto triangulated surfaces from 3D laser scanning. By these means, the effort to generate photo-realistic models of complex shaped objects can be reduced considerably. The images are collected from multiple viewpoints, which do not necessarily correspond to the viewpoints of LIDAR data collection. In order to handle ...

Consumer demand has increased for processed products that keep more of their original characteristics. In industrial terms, this requires the development of operations that minimize the adverse effects of processing. The effect of food processing on finished product quality ultimately determines the usefulness and commercial viability of that unit process operation. In the particular case of fo...
