Abstract: There is provided a computer implemented method of controlling movement of an object, comprising: accessing a current image of a surface relative to an object at a current location, wherein an imaging sensor is set to capture the current image depicting an overlap with a previously captured image of the surface when the object was at a previous location, registering the current image to the overlap of the previously captured image, computing the current location of the object relative to a reference location according to an analysis of the registration, and feeding the current location into a controller for controlling movement of the object.

Abstract: There is provided a retroreflector device, comprising: an incident object made of a material transparent to electromagnetic radiation, the incident object designed to refract an incident ray hitting an incident surface to generate a refracted ray that hits a back surface, and a retroreflective surface positioned in proximity to the back surface of the incident object, wherein the retroreflective surface and the incident object are configured to refract the incident ray to generate the refracted ray for hitting the retroreflective surface at an angle of incidence below a threshold.

Abstract: There is provided a system for guiding a steerable laser to a target object, comprising: at least one processor executing a code for: for each image of a plurality of images captured by an image sensor and obtained in a plurality of iterations: filtering an illumination of a steerable laser overlapping a target object or in near proximity to a target object from the image, to create a filtered image, detecting the target object on the filtered image by a detector model, and generating instructions for at least one of: further directing of the steerable laser for illumination of the target object, and maintaining the illumination of the steerable on the target object.

Abstract: There is provided a computer implemented method of detecting an attempt to breach security of an iris recognition system by an artificial iris, comprising: analyzing at least a portion of a limbal ring depicted in an image of an iris of an individual captured by an imaging sensor at a wavelength range within at least one of near infrared (NIR) and short wave infrared (SWIR), and detecting likelihood of an artificial iris worn by the individual according to the analysis of the at least the portion of the limbal ring.
