| Summary, etc. |
In the last few decades, new computer vision technologies and image<br/>processing techniques have been very important in the improvement<br/>and automation of manual processes in many technical areas, e.g.,<br/><br/>in the semiconductor industry. In this thesis, we propose and com-<br/>pare several techniques in the areas of pattern matching and machine<br/><br/>learning to have optical character recognition (OCR) of damaged or<br/>unreadable numerical digit characters from images on printed circuit<br/><br/>boards (PCBs). We describe how the best machine learning algo-<br/>rithms are applied to extract the principal characteristics and fea-<br/>tures to compute, classify and find the correct numerical character<br/><br/>that corresponds to those features. We also present our work in the<br/>improvement of the image quality in the pre-processing stage to make<br/>pattern matching a good option over some specific conditions of PCBs<br/>damage. |
