TLDR
In this paper, a dictionary including a target collection defined by images that are known with a defined level of certainty to include a subject and an imposter collection defined of images of individuals other than the subject is used.Abstract:
The method includes a dictionary including a target collection defined by images that are known with a defined level of certainty to include a subject and an imposter collection defined by images of individuals other than the subject. In the method, images of an area are captured over a period of time. In respect of each image: a matching calculation is carried out, based upon a comparison of the image captured with the images in the dictionary to result in a measure of confidence that the subject is in the area; and an inference determination is made to replace one of the target collection images with a further image that is known with the defined level of certainty, the determination being a function of the measure of confidence resultant from the captured image, the measure resultant from one or more previously captured images and the associated capture times.read more

Networked intoxication vehicle immobilization
TL;DR: In this article, a vehicle immobilization system includes a detection element (346) operable to detect a level of an intoxicant in a user's breath, and a control module (328) is able to receive a signal from the detection element indicating the level of intoxication in the user's blood, and to selectively restrict operation of a vehicle based on a threshold exceeding a threshold.

Robust Face Recognition via Sparse Representation
TL;DR: This work considers the problem of automatically recognizing human faces from frontal views with varying expression and illumination, as well as occlusion and disguise, and proposes a general classification algorithm for (image-based) object recognition based on a sparse representation computed by C1-minimization.

Toward a Practical Face Recognition System: Robust Alignment and Illumination by Sparse Representation
TL;DR: This work proposes a conceptually simple face recognition system that achieves a high degree of robustness and stability to illumination variation, image misalignment, and partial occlusion, and demonstrates how to capture a set of training images with enough illumination variation that they span test images taken under uncontrolled illumination.
