To provide a method and system suitable for classifying each image in a stream of images using a brain computer interface (BCI).SOLUTION: A method of classifying an image comprises: applying a computer vision procedure to an image to detect therein candidate image regions suspected as being occupied by a target; presenting to an observer each candidate image region in the form of a visual stimulus, while collecting neurophysiological signals from a brain of the observer; processing the neurophysiological signals to identify a neurophysiological event indicative of detection of the target by the observer; and determining the existence of the target in the image based, at least in part, on the identification of the neurophysiological event.SELECTED DRAWING: Figure 17
