1. An electronic device comprising: a first processor to receive image data representing an image frame from a first imaging camera and to determine two-dimensional (2D) spatial feature data representing one or more 2D spatial features identified from the image data, wherein the first processor is to process a portion of the image of data for identification of 2D spatial features while a next portion of the image data is being received from the first image camera; and a second processor, coupled to the first processor, to determine three-dimensional (3D) spatial feature data representing one or more 3D spatial features identified based on the 2D spatial feature data.
