Quality control is the applied set of constant tests and activities to maintain acceptable operating conditions and ensure that pre-established quality requirements are met. In industry, non-destructive testing is one of the most important technological advances to have taken place in recent times. Materials can be investigated without causing any structural changes. In the aluminum casting industry, the unsurpassed X-ray technology is used. The X-ray procedure aims to generate an image, which can be processed and must be of the highest quality. An example of the practical and theoretical use involved in the research is the wavelet transform. It was used for the spatial localization of different frequencies contained in images. The work carried out offers the suggestion of a digital image unit for processing, operating in partnership between industry and the university. This book is the result of the author's full-time research and development work in the state of São Paulo.
