eVes technology implementation supports two-dimensional, static, digital images. These images can be still photographs or video keyframes. They can also be bitonal (black and white) images, grayscale photographs, or color photographic images.
The source of the images is unimportant: they might be produced by a scanner, a digital camera, a video recorder connected to a digitizer or frame grabber, or even generated by a program. A digital image capture device converts an analog signal, such as light in a traditional camera, into discrete digital values on a two-dimensional grid of pixels.
