1. An image processing apparatus for extracting a feature from an image of a scene, wherein the apparatus comprises:
at least one of an optical splitter or a dedicated prism;
a first imaging sensor;
a second imaging sensor;
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
receive an optical signal;
split, using the at least one of the optical splitter or the dedicated prism, the optical signal into a first optical signal and a second optical signal;
capture, using the first imaging sensor, a first image of the scene using the first optical signal;
provide first image data representing the first image of the scene;
capture, using the second imaging sensor, a second image of the scene using the second optical signal;
provide second image data representing the second image of the scene;
adjust at least one of a frame rate or a resolution of the first imaging sensor based on a feature extraction event identified from the second image data; and
in response to the feature extraction event, extract a feature from the first image data.
