1. An optical-imaging apparatus comprising:
- at least two optical sensors disposed in a chosen spatial configuration such that neighboring optical sensors included in said at least two optical sensors have overlapping fields of view, for receiving optical signals from an object at least a portion of the image of which object is located within the field of view of said at least two optical sensors, said at least two optical sensors having analog outputs;
means for measuring the analog outputs of said at least two optical sensors in response to the optical signals in parallel; and
means for processing the analog outputs to generate image features of the object.

Abstract
An apparatus and method for providing image primitives, such as edge polarity, edge magnitude, edge orientation, and edge displacement, and derivatives thereof, for an object are described. The data are obtained substantially simultaneously and processed in parallel such that multiple objects can be distinguished from one another in real time.

9. A method for obtaining image features from an object, comprising the steps of:
-
receiving optical signals from the object on at least two optical sensors having overlapping fields of view within which at least a portion of the image of the object is located, and analog outputs;
measuring the analog outputs of the at least two optical sensors responsive to the optical signals in parallel; and
processing the analog outputs to generate image features. - View Dependent Claims (10, 11, 12, 13, 14, 15)
