Abstract: Methods and systems for dewarping images allow a user to reduce distortion in scanned images. A scanned image is processed using an optics model and an illumination model, and resampled to reduce distortion. The dewarping may be improved through iterative operations where a model parameter is varied. An optimal image is obtained which corresponds to a maximum metric as a measure of the quality of a resampled image.

Abstract: This connection device comprises: an insulating casing comprising at least one opening in order to insert the electrical cable, a connection element which is placed in the insulating casing and which comprises at least one connection spring intended to grip the conducting core of the cable or the plug-in connector, and a pusher associated with the connection element in order to compress the spring and enable the electrical cable or the plug-in connector to be put in place. The pusher has a passage called a test passage, enabling a measuring device to be brought into contact with part of the connection element.
