System and method to determine awareness
First Claim
Patent Images
1. An awareness detection system, comprising:
- an imaging device adapted to acquire data representative of an image of a subject; and
an awareness processor connected to said imaging device, wherein said awareness processor is adapted to determine a particular region within said image, size and establish said particular region, augment and normalize data of said image in said particular region with a distribution enhancement technique, represent said image within a fixed space with a vector relating technique that includes a reconstruction error determined in a fixed point system relative to a floating point system, which is used to classify an awareness state of the subject according to an orientation of the subject represented by the normalized data and said vector relating technique.

13. A method for determining awareness of a subject, comprising the steps of:
-
acquiring data representative of an image of a subject, wherein said image is acquired by an imaging device; processing said data by an awareness processor, said processing including, identifying a particular region of said image data; and augmenting and normalizing the data in said particular region to a pre-defined size with a distribution enhancement technique; representing said image within a fixed space with a vector relating technique that includes a reconstruction error determined in a fixed point system relative to a floating point system; and classifying subject awareness based on the orientation of a portion of the subject represented by the normalized data in said particular region and said vector relating technique. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
