Real-Time Automatic Inspection System for the Classification of PCB Flux Defects

A 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...

Automatic Detection of PCB Defects

A Printed Circuit Board (PCB) is everywhere from a small toy to a big electronic machine which we used in our daily life. PCB consists of circuit with various electronic components mounted on surface. PCB manufacturing consists of three stages in which inspection of PCB necessary to reduce the defects. First is printing, second is component fabrication over PCB surface and third is the componen...

Automatic PCB Inspection Algorithms: A Survey

1 abstract The importance of the inspection process has been magniied by the requirements of the modern manufacturing environment. In electronics mass-production manufacturing facilities, an attempt is often made to achieve 100 % quality assurance of all parts, subassemblies, and nished goods. A variety of approaches for automated visual inspection of printed circuits have been reported over th...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Real time automatic scene classification

This work has been done as part of the EU VICAR (IST) project and the EU SCOFI project (IAP). The aim of the first project was to develop a real time video indexing classification annotation and retrieval system. For our systems, we have adapted the approach of Picard and Minka [3], who categorized elements of a scene automatically with so-called ’stuff’ categories (e.g., grass, sky, sand, ston...
