Abstract: An accelerator and a system for accelerating operations are disclosed. A respective apparatus comprises an interface configured to couple the apparatus to an interconnect, a plurality of processing modules, each processing module configured to process data, a control module configured to control processing of each of the plurality of processing modules, and a cache module configured to store at least a portion of data processed by at least one of the plurality of processing modules. Each processing module includes a processing core configured to process data by performing an operation on the data using a plurality of processing elements, an input control unit configured to retrieve data via the interface and data stored in the cache module and to provide the retrieved data to the processing core, and an output control unit configured to provide data processed by the processing core to the interface and the cache module.

Abstract: The invention is a method for camera misalignment detection by means of processing images of a camera fixed to a vehicle and having a field of view containing a vehicle image area (11) imaging a portion of the vehicle and a remaining area (12), wherein in said processing step a plurality of reference locations (21) within an input image are used, said reference locations (21) being determined as edge locations along a boundary of the vehicle image area (11) in a reference image, and said processing step comprises checking at the reference locations (21) within the input image whether said reference locations (21) are edge locations by ascertaining at each reference location (21) whether a magnitude of an image gradient is above a gradient threshold limit, and alerting misalignment depending on an ascertained subset of the reference locations (21) where the gradient threshold limit is not reached.

Abstract: The invention provides a method, a system and a computer-readable medium for calibrating a camera by using a multi-pattern calibration rig, each pattern being repetitive and comprising calibration shapes, wherein the following steps are carried out: capturing an image of the multi-pattern calibration rig with the camera, segmenting contours of the imaged calibration shapes, building groups of coherent contours based on the similarity of their shapes and their distances from each other, and identifying the positions of the patterns in the image based on the contour groups.
