- When motion blur is analyzed as the integration over curves resulting from camera and object motion, the only integration curve that results in a motion-invariant PSF is a parabola. This corresponds to constant 1D acceleration of …
Motion-Invariant Photography

- In order to derive a motion–invariant photography scheme, we char-acterize motion blur as an integration in space–time. We show that the effect of object motion can be characterized by a shear. We also show that a camera parabolic movement is invariant to shear in space–time and permits the removal of motion blur. Space–time analysis of ...
Motion-Invariant Photography - MIT CSAIL

- Through the analysis of motion blur as space-time integration, we show that a parabolic integration (corresponding to constant sensor acceleration) leads to motion blur that is invariant to object velocity. Thus, a single deconvolution kernel can be used to remove blur and create sharp images of scenes with objects moving at different speeds ...

- Object motion during camera exposure often leads to noticeable blurring artifacts. Proper elimination of this blur is challenging because the blur kernel is unknown, varies over the image as a function of object velocity, and destroys high frequencies. In the case of motions along a 1D direction (e.g. horizontal) we show that these challenges ...

- Motion Invariant Photography Technology #13075 Applications This technology is camera hardware designed to remove motion blur from photographs. Problem Addressed Motion blur often limits the quality of photographs and can be caused by either the shaking of the camera or the movement of objects in the scene. Modern cameras use image ...

- Near-Invariant Blur for Depth and 2D Motion via Time-Varying Light Field Analysis. ACM Transactions on Graphics, Vol. 32, No. 2, Article 13, 2013. Standard camera image suffers from both defocus and motion blur if the scene has moving objects at various depths (left). Blur can be made nearly identical irrespective of scene depth or motion by ...
