Periodicity Estimation of Regular Textile Fabrics Based on Energy Function

Machine Vision Based Inspection of Textile Fabrics

Several issues on automatic inspection of textile fabrics are discussed in this paper. To avoid the intense computation for real time inspection, we suggest a parallel pyramid hardware architecture consisting of several channels with CCD cameras in different resolutions working simultaneously. In inspection algorithms, we use a hierarchy of improved BP neural networks which demonstrate a tree s...

On the use of image processing techniques for the estimation of the porosity of textile fabrics

This paper presents a novel approach to assessing textile porosity by the application of the image analysis techniques. The images of different types of sample fabrics, taken through a microscope when the fabric is placed over a constant light source, transfer the problem into the image analysis domain. Indeed, porosity can thus be expressed in terms of a brightness percentage index calculated ...

Estimation Based on an Appropriate Choice of Loss Function

Some examples of absurd uniformly minimum variance unbiased estimators are discussed. Two reasons, argued in the literature, for having such estimators are lack of enough information in the available data and property of unbiasedness. In this paper, accepting both of these views, we show that an appropriate choice of loss function using a general concept of unbiasedness leads to risk unb...

Overview of Flow through Textile and Fabrics

An overview of single and multiphase flows through woven and nonwoven fibrous materials is presented. A computational model for analyzing fluid flow through such media is described and sample computational results are presented. It is shown that by generating virtual geometries that resemble the microstructure of a fibrous material one can study the fluid and particle transport through such por...
