Rotational invariance in visual pattern recognition by pigeons and humans.
Pigeons and humans chose which one of two alternative visual forms was identical to, or a mirror image of, a previously presented sample form. The two comparison forms were presented in various orientations with respect to the sample. The two species yielded similar accuracies, but although human reaction times depended linearly on the angular disparities, those of the pigeon did not. Humans ap...
متن کاملSome results on translation invariance in the human visual system.
Four experiments were conducted to study the nature of visual translation invariance in humans. In all the experiments, subjects were trained to discriminate between a previously unknown target and two non-target distractors presented at a fixed retinal location to one side of the fixation point. In a subsequent test phase, this performance was compared with the performance when the patterns we...
متن کاملVisual Pattern Recognition
Perceiving the visual world around us is one of the most basic acts of everyday experience. Although pattern recognition may seem effortless, it is actually a complex problem--so much so that the visual areas responsible for this process occupy up to one-half of our cortex. Fundamental to our perception is the transformation of the light array that falls on our retinae into coherent surfaces an...
متن کاملInteractive Visual Pattern Recognition
Computer Assisted Visual Interactive Recognition (CAVIAR) draws on sequential pattern recognition, image database, expert systems, pen computing, and digital camera technology. It is designed to recognize wild flowers and other families of similar objects more accurately than machine vision and faster than most laypersons. The novelty of the approach is that human perceptual ability is exploite...
متن کاملLearning and disrupting invariance in visual recognition
Learning by temporal association rules such as Foldiak’s trace rule [1] is an attractive hypothesis that explains the development of invariance in visual recognition. Consistent with these rules, several recent experiments have shown that invariance can be broken by appropriately altering the visual environment but found puzzling differences in the effects at the psychophysical [2, 3] versus si...
