1. An object detection arrangement comprising:
a plurality of image capturing devices; and
a controller configured to:
receive a plurality of image data streams, each of the plurality of image data streams originating from one of the plurality of image capturing devices;
perform local feature extraction on each of the received plurality of images to provide a plurality of feature data streams;
perform a common feature extraction at least by applying a plurality of neural network layers exhibiting temporal dynamic behavior to the plurality of feature data streams, the plurality of neural network layers being arranged such that one of the plurality of neural network layers receives input from another of the plurality of neural network layers not immediately preceding the one of the plurality of neural network layers, the common feature extraction being based on the plurality of feature data streams to provide a common feature data stream for object detection; and
at least one of the plurality of image capturing devices is configured to perform the local feature extraction on a corresponding image data stream.
