On Patchworks and Hierarchies

A Study on the Value Systems of the Fourth Region of the I.A.U

This paper aims to study and examine the value systems among the students region of Islamic Azad universities. The population includes all students in academic year 2008-9 among whom 400 ones were selected from 10 universities as a sample. The students' value hierarchies were examined using Alpourt 45- item questionnaire(A.V.L). Descriptive and t-inferential statistics and multivariate variance...

PatchWorks: Example-Based Region Tiling for Image Editing

Filling regions of an image in a seamless manner is an important task for editing digital images. We propose to address it by using an example-based image generation technique. Such techniques have recently proved very effective in the context of unconstrained texture synthesis. We show that they can also be surprisingly effective to fill large regions in images, even within complex mixes of te...

Application of modified balanced iterative reducing and clustering using hierarchies algorithm in parceling of brain performance using fMRI data

Introduction: Clustering of human brain is a very useful tool for diagnosis, treatment, and tracking of brain tumors. There are several methods in this category in order to do this. In this study, modified balanced iterative reducing and clustering using hierarchies (m-BIRCH) was introduced for brain activation clustering. This algorithm has an appropriate speed and good scalability in dealing ...

Segmentation of random textures by morphological and linear operators

We propose a linear and a morphological approach for the characterization and segmentation of binary and digital random textures. We focus on descriptors at the level of pixels in images, combined with statistical learning to select and weight them. The approach is illustrated on simulations of textures patchworks, for which errors of classification can be evaluated.
