Automatic Detection and Localization of Surface Cracks in Continuously Cast Hot Steel Slabs Using Digital Image Analysis Techniques
Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...
متن کاملA Hybrid Optical Digital Image Processing Method for Surface Inspection
A hybrid measurement technique is proposed for high-precision surface inspection. The technique uses an interferometer to image microscopic surface defects. In order to quantify the degree of various surface defects, the interferograms are scanned, digitized, and subsequently converted to a binary image by using an adaptive thresholding technique which takes into account the inhomogeneity of th...
متن کاملAutomatic Image Processing For Welding Inspection
This paper deals with the automatic detection of defects within various welding. The authors propose a method based on taking an X-ray image of the welding and then applying various image processing algorithms for the detection of possible defects. This method has a significant improvement in the detection success ratio compared to classical detection techniques (by using human operators). Key-...
متن کاملA Real-Time Automatic Inspection System for Pattavia Pineapples
This paper presents a machine vision method to inspect the maturity of pineapples that ripe naturally. Unlike previous methods, the proposed technique can be categorized as a real-time non destructive testing (Real-Time NDT) approach. It consists of two phases, learning and recognition phases. In the learning phase, the system constructs a library of reference pineappleskin-color models. In the...
متن کاملReal-time surface inspection by texture
In this paper a real-time surface inspection method based on texture features is introduced. The proposed approach is based on the Local Binary Pattern (LBP) texture operator and the Self-Organizing Map (SOM). A very fast software implementation of the LBP operator is presented. The SOM is used as a powerful classifier and visualizer. The efficiency of the method is empirically evaluated in two...
