Processing images of at least one living being
TLDR
In this article, a method of processing images of at least one living being, including obtaining a sequence (19) of digital images taken at consecutive points in time, is proposed. But the method is not suitable for the detection of individuals.Abstract:
A method of processing images of at least one living being, includes obtaining a sequence (19) of digital images taken at consecutive points in time. At least one measurement zone (26) comprising a plurality of image points is selected. For each measurement zone (26), a signal (28,30) representative of at least variations in a time- varying value of a combination of pixel values at at least a number of the image points for use in determining at least one of a presence and a frequency value of at least one peak in a spectrum of the signal (28,30) corresponding to a frequency of a periodic physiological phenomenon is obtained. The step (25) of selecting at least one measurement zone (26) includes analyzing information based on pixel data of a plurality of image parts in at least one of the images (19), each image part including at least one image point, and selecting each measurement zone (26) from contiguous parts determined to have similar characteristics.read more

Device and method for determining patient's vital signs
TL;DR: In this paper, the authors proposed a method for determining information on vital signs of a patient based on electromagnetic radiation received from a patient in the field-of-view of the detection device, where the selection unit is configured to select an area for determining a second time-dependent signal based on the variable signals.

Robust Real-Time Face Detection
Paul A. Viola,Michael Jones +1 more
TL;DR: In this paper, a face detection framework that is capable of processing images extremely rapidly while achieving high detection rates is described. But the detection performance is limited to 15 frames per second.

Robust real-time object detection.
TL;DR: Viola et al. as mentioned in this paper proposed a visual object detection framework that is capable of processing images extremely rapidly while achieving high detection rates using a new image representation called the integral image, which allows the features used by the detector to be computed very quickly.

Remote plethysmographic imaging using ambient light
TL;DR: Plethysmographic signals were measured remotely (>1m) using ambient light and a simple consumer level digital camera in movie mode as discussed by the authors, which may be useful for medical purposes such as characterization of vascular skin lesions and remote sensing of vital signs (e.g., heart and respiration rates) for triage or sports purposes.
