Motion perception: How are moving images segmented?
The process of image segmentation is one of the key elements in making sense of the complex visual world around us; it enables the features and attributes that are mapped on the eye and in the brain to be grouped into objects which we perceive as discrete entities. This process has been intensively studied by perceptual psychologists and computational vision scientists because of its importance...
متن کاملSeeing blur: 'motion sharpening' without motion.
It is widely supposed that things tend to look blurred when they are moving fast. Previous work has shown that this is true for sharp edges but, paradoxically, blurred edges look sharper when they are moving than when stationary. This is 'motion sharpening'. We show that blurred edges also look up to 50% sharper when they are presented briefly (8-24 ms) than at longer durations (100-500 ms) wit...
متن کاملSharpening of drifting, blurred images
The perceived blur of moving images is less than expected given the sluggish temporal response of the visual system. This suggests that a motion deblurring mechanism may exist to preserve the positional acuity and sharpness of moving images. Furthermore, when sequences of blurred stills are presented, observers report that the moving image is in sharp focus raising the possibility that there is...
متن کاملMotion blur and motion sharpening in the human visual system
The effect of motion sharpening upon blur discrimination thresholds was examined for a range of speeds and blur widths. Blur discrimination thresholds were measured for drifting edges whose blur was either physically or perceptually constant. Under conditions where edges were kept at a constant physical blur width, discrimination thresholds rose as a function of speed as previously reported. Ho...
متن کاملLinear mechanisms can produce motion sharpening
Human observers are not normally conscious of blur from moving objects [Nature 284 (1980) 164]. Several recent reports have even shown that blurred images appear sharper when drifting than when stationary and have suggested different non-linear mechanisms to explain this phenomenon [Vision Res. 36 (1996) 2729; Vision Res. 38 (1998) 2099]. We demonstrate here that even though distortions of drif...
