Currently, the low-level image features such as color, texture, and shape are widely used for content-based image retrieval. However, it is rather difficult to realize an exact match between two images by using a single feature. To address this problem, a method combining color spatial distribution and shape of the object is presented. In this method, firstly, an improved mean shift algorithm i...

Background and Aim: Color match between prosthetic restorations and natural teeth is challenging in dentistry. The aim of the current study was to assess the effect of accelerated aging on color stability of two silica-based ceramics with leucite and lithium disilicate crystalline phases after glazing and polishing surface treatments. Materials and Methods: In this experimental study, 30 disc-...

A project to evaluate current practices in fine art image reproduction is conducted in which pieces of artwork in various media are being imaged by participating museums. As part of this project, observers were asked to make adjustments in softcopy fine art reproductions. The goal is to see how people working in museums, libraries and archives make color adjustments to artwork presented to them...

High-dynamic-range (HDR) images were embodied by a lot of algorithms. This paper takes notice one of these algorithms, which is iCAM06. iCAM06 has worked color appearance prediction of HDR images based on CIECAM02 color prediction and incorporates the spatial processing models in the human vision system for contrast enhancement. We investigated the effect of user controllable factors of iCAM06 ...

Motivation: In our previous approach, we proposed a hybrid method for protein secondary structure prediction, called HYPROSP, which combined our proposed knowledge-based prediction algorithm PROSP and PSIPRED. The knowledge base constructed for PROSP contains small peptides together with their secondary structural information. The hybrid strategy of HYPROSP uses a global quantitative measure, m...
