This paper investigates the influence of ultraviolet (UV) lighting configurations on the automatic detection of Regions of Interest (ROIs) and the visual identification of surface defects in cast metal parts. A meticulous experimental setup was devised employing four UV light bars arranged in a rectangle, with varying combinations of active light sources. The study utilized the OpenCV library to automate the detection of mounting holes (ROIs) on the cast metal parts. Additionally, a visual inspe...

Here, we present the VisioBioshapeR package for R [R
Core, 2014]. This new library is a comprehensive, multifunctional toolbox designed to
automatically analyse biological images. The package extends other common libraries (Momocs,
ShapeR) used for biological shape analysis by allowing the user to extract
closed contour outlines automatically from reading binary
images. Current functionalities of VisioBioshapeR include: random ext
