    Abstract: A configuration system generates a calibration target to be printed, the target including a set of machine-readable and visually-identifiable landmarks and associated location-encoding marks which encode known locations of the landmarks. A plurality of test images of the printed calibration target is acquired by the system from an image capture assembly. Positions of the landmarks in the acquired test images and the location-encoding marks in the acquired test images are detected by the system. The system decodes the locations of the landmarks from the detected location-encoding marks and spatially characterizes the image capture assembly, based on the detected positions of the landmarks in the acquired test images and their decoded known locations.

    Abstract: A store profile generation system includes a mobile base and an image capture assembly mounted on the base. The assembly includes at least one image capture device for acquiring images of product display units in a product facility, product labels being associated with the product display units which include product-related data. A control unit acquires the images captured by the at least one image capture device at a sequence of locations of the mobile base in the product facility. The control unit extracts the product-related data from the acquired images and constructs a store profile indicating locations of the product labels throughout the product facility, based on the extracted product-related data. The store profile can be used for generating new product labels for a sale in an appropriate order for a person to match to the appropriate locations in a single pass through the store.

    Abstract: Methods and systems are disclosed for updating camera geometric calibration utilizing scene analysis. Geometric calibration parameters can be derived with respect to one or more cameras and selected reference points of interest identified from a scene acquired by one or more of such cameras. The camera geometric calibration parameters can be applied to image coordinates of the selected reference points of interest to provide real-world coordinates at a time of initial calibration of the camera(s). A subset of a video stream from the camera(s) can then be analyzed to identify features of a current scene captured by the camera(s) that match the selected reference points of interest and provide a current update of the camera geometric calibration parameters with respect to the current scene.

    Abstract: Methods and systems present, to a user, different versions of sample images. Each of the sample images is classified into at least one image-element category of multiple image-element categories. Such methods and systems request the user to select preferred versions of the sample images from the different versions of the sample images, and receive in response a user selection of preferred images. The methods and systems determine user-specific preferences for each of the image-element categories based on the user selection of the preferred images. The methods and systems receive an image-processing request relating to user images from the user, and classify the user images into the image-element categories. When processing the image-processing request, the methods and systems alter renditions of the user images according to the user-specific preferences for each image-element category.
