Abstract: Various techniques facilitate the development of an image library that can be used to train and/or validate an automated visual inspection (AVI) model, such an AVI neural network for image classification. In one aspect, an arithmetic transposition algorithm is used to generate synthetic images from original images by transposing features (e.g., defects) onto the original images, with pixel-level realism. In other aspects, digital inpainting techniques are used to generate realistic synthetic images from original images. Deep learning-based inpainting techniques may be used to add, remove, and/or modify defects or other depicted features. In still other aspects, quality control techniques are used to assess the suitability of image libraries for training and/or validation of AVI models, and/or to assess whether individual images are suitable for inclusion in such libraries.

Abstract: A light control system including a light source and a light management unit (LMU) operative to receive a light output control signal and to control a light output emitted from the light source, wherein the LMU controls the light output from the light source based on the light output control signal.

Abstract: A shell catcher for use with hand-held firearms adjustably detachably mounts on a side of the firearm for receiving and retaining spent shells expelled by the firearm. The shell catcher has a base, which mounts on a side of the firearm and a collapsible flexible housing, which is detachably pivotally mounted on the mounting base. The housing is stretched on a rigid frame that moves between a closed position when the shells are received in the housing and an open position allowing unobstructed view of the gun chamber. The spent shells are removed from the housing by means of opening the bottom of the housing or by removing the housing from the base.
