Claim Text:
1. A method of providing a combination of video data and metadata comprising the acts of: obtaining a sequence of images captured by a video camera, the sequence of images including subject images of at least one subject; extracting at least one signal from at least part of the sequence of images representing the subject images, wherein each of the at least one extracted signal characterizes local temporal variations in at least one of light intensity and color of light captured from the at least one subject represented in the at least part of the sequence of images; generating metadata (i) based on the at least one extracted signal that characterizes local temporal variations in at least one of light intensity and color of the at least one subject represented in the at least part of the sequence of images, (ii) for characterizing at least one biometric process in the at least one subject represented in the at least part of the sequence of images, wherein the biometric process causes the local temporal variations in at least one of color and intensity of light captured from the at least one subject; applying at least one video compression technique on image data of images from the sequence to obtain compressed video data, wherein the at least one extracted signal is extracted from images in a state prior to the application of the at least one compression technique to image data from those images; and providing the compressed video data with the generated metadata.
