Design of a machine to rectify ceramic tiles for laboratory tests

Graphic Design for Ceramic Tiles

The development of a computer based design system for ceramic tiles forms part of a BriteEuram project aimed at providing automated quality control for ceramic tile production. The design system is expected to provide a priori information about each tile design to the quality control inspection stations. The differences between graphic design for paper and graphic design for ceramic are discuss...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Automatic color grading of ceramic tiles using machine vision

We present a method designed to solve the problem of automatic color grading for industrial inspection of plain and patterned ceramic tiles. We discuss problems we were confronted with, like the temporal and spatial variation of the illumination, and the ways we dealt with them. Then, we present results of correctly grading a series of ceramic tiles, the differences of which were at the thresho...

To Rectify an Amoral Design

A New Algorithm for Detecting Texture Defects of Ceramic Tiles

In this paper a new algorithm to detect texture defects of ceramic tiles is proposed. The proposed algorithm has two stages: feature extraction and inspection. In the feature extraction stage, the parameters of proposed algorithm is determined using one (few) reference ceramic tile(s) with no defect. At first, the colors of the texture are clustered to form a model of texture colors. Then, each...
