EVENT BASED COMPUTER VISION COMPUTATION

摘要

Certain techniques are provided for triggering events based on detecting changes in CV features, such as edges, corners etc., by generating computed results based on sensor readings. Yet other techniques also provided for detecting CV features once an event is detecting based on a change in a sensor reading for a sensor element. In certain aspects, the event detection logic and the feature calculation CV vision operations may be performed, individually, or in combination in circuitry on a sensor or in software/firmware on a computing device.

1. A method for generating computed results based on sensor readings, the method comprising:
receiving at least one sensor reading based on light incident upon a subject sensor element, wherein the subject sensor element is from a sensor element array comprising a plurality of sensor elements, the plurality of sensor elements arranged along at least a first dimension and a second dimension of the sensor element array; computing a localized computer vision (CV) feature, using dedicated CV computation hardware, based on the at least one sensor reading for the subject sensor element and neighboring sensor elements for the subject sensor element; and generating an event based on a change in the computed CV feature from a previously computed CV feature for the subject sensor element, the event including information relating to a location of the subject sensor element associated with the change in the computed CV feature.
