BACKGROUND This paper discusses an image-processing method applied to skin texture analysis. Considering that the characterisation of human skin texture is a task approached only recently by image processing, our goal is to lay out the benefits of this technique for quantitative evaluations of skin features and localisation of defects. METHODS We propose(More)
Statistical pattern recognition methods based on the Coherence Length Diagram (CLD) have been proposed for medical image analyses, such as quantitative characterization of human skin textures, and for polarized light microscopy of liquid crystal textures. Further investigations are here made on image maps originated from such diagram and some examples(More)
The maximum entropy principle is often used for bi-level or multi-level thresholding of images. For this purpose, some methods are available based on Shannon and Tsallis entropies. In this paper, we discuss them and propose a method based on Kaniadakis entropy. 1. Introduction The concept of entropy was born in thermodynamics and statistical mechanics.(More)
We are proposing a tool able to gather information on social networks from narrative texts. Its name is CHAPLIN, CHAracters and PLaces Interaction Network, implemented in VB.NET. Characters and places of the narrative works are extracted in a list of raw words. Aided by the interface, the user selects names out of them. After this choice, the tool allows(More)
The paper describes an image processing for a non-photorealistic rendering. The algorithm is based on a random choice of a set of pixels from those of the original image and substitution of them with colour spots. An iterative procedure is applied to cover, at a desired level, the canvas. The resulting effect mimics the impressionist painting and(More)
