Abstract: Systems for visually inspecting a surface of an object are provided, which includes a visual inspection head, and a positioning apparatus for controlling a position and/or an orientation of the visual inspection head with respect to the object. The visual inspection head includes a visual inspection module, and an angle controlling module for ensuring a predetermined angle of the visual inspection system with respect to an area to be inspected of the surface of the object. The angle controlling module may include a pointer for projecting a light beam onto the area to be inspected and a camera for determining whether the light beam is reflected substantially perpendicularly. The system is configured to move the visual inspection head relative to the object until the light beam is reflected substantially perpendicularly. Methods for visually inspecting a surface are also provided.

Abstract: A method for digital image processing is bioinspired and includes an architecture that emulates the functions of photoreceptors, horizontal cells, bipolar cells and ganglion cells of a primate retina based on an image as input. The method detects edges and properties of the surfaces present in the digital image. The output is a data set that includes photoreceptor emulators that emulate photoreceptor cells and connected to the data input. Each emulator includes a cellular base structure with a modulated data input, a calculation center to process the modulated data and an output of the data processed by the calculation center, and the emulators forming a virtual retina in which each emulator is parameterized.

Abstract: A method of processing color attributes of digital images is bioinspired and includes an architecture that emulates the functions of the retina of a primate based on an image as input. The method detects the color attributes in the image. The output is a data set that includes emulators that a virtual retina in which each emulator is parameterized and in which there are emulators of type G ON and G OFF midget ganglion cells, emulators of bistratified ganglion cells, and emulators of type R ON and OFF midget ganglion cells each connected to a plurality of type R ON and OFF midget bipolar cell emulators which in turn are connected through horizontal cell emulators, to a plurality of type L cone photoreceptor emulators and to a plurality of horizontal emulators and generates a third colour channel (A) of output signals.
