An efficient dilation-based clustering algorithm for automatic optical inspection
2012 11th International Conference on Information Science, Signal Processing and their Applications (ISSPA), 2012This paper develops an efficient dilation-based clustering algorithm (DBCA) by using run-length encoding (RLE). The fundamental concept of dilation-based connectivity and its limitation are described in the beginning. Subsequently, the architecture of DBCA is constructed in the following procedures: (1) run-length encoding, (2) RLE-based morphological ...

Study of automatic optical inspection for golf logo quality
Journal of Electronic Imaging, 2007Currently, inspection of the quality of a golf logo requires much time and manpower. There is a demanding need to reduce the escape rate. We present a preliminary but innovative study on development of an automatic optical inspection (AOI) system for golf logo quality.

Modern Architecture for Deep Learning-Based Automatic Optical Inspection
2019 IEEE 43rd Annual Computer Software and Applications Conference (COMPSAC), 2019The advanced optical inspection of manually placed components on through-hole printed circuit boards demands robust and fast classifiers. To train such classifiers, one needs vast amounts of previously labeled sample images. Datasets like this are currently not available and thus hinder the deployment of deep-learning algorithms in environments like ...

Automatic Optical Inspection aided Augmented Reality-based PCBA Inspection: A Development
2019 IEEE Jordan International Joint Conference on Electrical Engineering and Information Technology (JEEIT), 2019Augmented Reality-based (AR-based) inspection has been demonstrated to be up to 2-3 times more efficient than the traditional manual and computer-based inspection. Previous studies have focused on standalone inspection systems often relying on external markers for registration. In this study, we present a novel optical see-through head-mounted display (

New multicolor illumination system for automatic optical inspection
SPIE Proceedings, 2010In automatic optical inspection (AOI), the illumination system affects the quality of input images and the result of image processing in the AOI. This paper developed a new multi-color illumination system specially used in the printed circuit board (PCB) inspection to detect a variety of defects in automated optical inspection system.
