With an eye to low vision: optic flow enables perception despite image blur.
PURPOSE From static blurry images, it is difficult to perceive objects because high spatial frequency details are filtered out. However, in the context of events (defined as objects in motion), motion generates optic flow, which provides a depth map of 3D layout and allows good event perception. Visual motion measurement uses low spatial frequencies that remain available in blurry images, makin...
متن کاملMotion-generated optical information allows event perception despite blurry vision in AMD and amblyopic patients.
Events consist of objects in motion. When objects move, their opaque surfaces reflect light and produce both static image structure and dynamic optic flow. The static and dynamic optical information co-specify events. Patients with age-related macular degeneration (AMD) and amblyopia cannot identify static objects because of weakened image structure. However, optic flow is detectable despite bl...

این پایان نامه سعی بر این دارد که تصویری از آنچه طبیعت در ادبیات پسااستعمارگری بدان شبیه است ارائه دهد. وول سوینکا، نویسنده ی اهل نیجریه و برنده ی جایزه ی نوبل ادبیات، در نمایش نامه های برجسته اش به نام های رقص جنگل ها (????) و ساکنین مرداب (????) محیط را به عنوان ویژگی ذاتی در ادبیات پسااستعمارگری به تصویر می کشد. بعلاوه، وول سوینکا دیدگاه و درک پسااستعمارگری خود را بواسطه ی پایداری گرایش های ...
Embodied memory allows accurate and stable perception of hidden objects despite orientation change.
Rotating a scene in a frontoparallel plane (rolling) yields a change in orientation of constituent images. When using only information provided by static images to perceive a scene after orientation change, identification performance typically decreases (Rock & Heimer, 1957). However, rolling generates optic flow information that relates the discrete, static images (before and after the change)...
متن کاملOptic flow and depth perception.
The field of depth recovery from optic flow has recently experienced much growth, both on the theoretical and on the empirical fronts. Unfortunately, the theoretical results are not as widely known to perception workers as they might be. This article gives a simple analysis of the information for depth present in optic flow. It also reviews the psychophysical results for depth recovery from mot...
