Memory colours refer to the colour of specific image classes that have the essential attribute of being perceived in a consistent manner by human observers. In colour correction -or renderingtasks, this consistency implies that they have to be faithfully reproduced; their importance, in that respect, is greater than other regions in an image. Before these regions can be properly addressed, one ...

We propose an automatic algorithm, named SDI, for the segmentation of skin lesions in dermoscopic images, articulated into three main steps: selection of the image ROI, selection of the segmentation band, and segmentation. We present extensive experimental results achieved by the SDI algorithm on the lesion segmentation dataset made available for the ISIC 2017 challenge on Skin Lesion Analysis ...

The automatic segmentation of Chinese text is an ongoing problem in information retrieval (IR) and computational linguistics: “words” in written Chinese are not delimited by spaces so tokenizing (the first phase of many IR tasks) is considerably more difficult than for Western languages. This paper presents an overview of the segmentation problem, detailing previous research into its solution a...

One of the most striking aspects of redshift surveys is that there are huge regions of space totally devoid of galaxies. These are the cosmic voids, which grew hierarchically from the initial density troughs in the primordial fluctuation field. In a hierarchical structure formation scenario smaller voids build up larger ones; the void hierarchy. In this paper we study the void evolution and mer...

This paper presents a new method for segmentation of molecular surfaces. Topological analysis of a scalar function defined on the surface and its associated gradient field reveals the relationship between the features of interest and critical points of the scalar function. The segmentation is obtained by associating segments with local minima/maxima. Controlled simplification of the function me...

Social Media Posts On Platforms Such As Twitter Or Instagram Use Hashtags, Which Are Author-Created Labels Representing Topics Or Themes, Toassist In Categorization Of Posts And Searches For Posts Of Interest. The Structural Analysis Of Hashtags Is Necessary As Precursor To Understandingtheir Meanings. This Paper Describes Our Work On Segmenting Nondelimited Strings Of Hashtag-Type English Text...

The paradigm of minimal length encoding is used for superior segmenting and compressing of waveforms. These methods sre shown to be applicable also for segmenting and edge nding in pictures.

The accurate and effective algorithm for segmenting image is very useful in many fields, especially in medical image. In this paper we introduced a novel method that focus on segmenting the brain MR Image that is important for neural diseases. Because of many noises embedded in the acquiring procedure, such as eddy currents, susceptibility artifacts, rigid body motion, and intensity inhomogenei...

Five experiments performed in a desktop virtual-reality setting investigated the influence of environmental features—that is, noticeable landmarks along the route—on distance estimation. Landmarks were of two types: Either they simply “filled” the route or they “filled” and also segmented it, thereby inducing a hierarchical structuring of the route. Previous research had left the question open ...
