1. A method for identifying objects in an image comprising: receiving an image with a first resolution, the image representing a scene including objects; transforming, by a computer, the image at the first resolution to an image at a second resolution, the first resolution being higher than the second resolution; processing, by the computer, the image at the second resolution to identify an object, from among the objects included in the received image, in the image at the second resolution; selecting a detection algorithm from among plural detection algorithms based on a condition associated with the object identified at the second resolution; and processing, by the computer, the image at the first resolution using the object identified at the second resolution to identify another object, from among the objects included in the received image, in the image at the first resolution according to the selected detection algorithm.
