Hi,Is there a possibility that we could determine the direction of motion in an image using RADON transformation?. If yes please tell me how to .If no, please suggest me how to detect the direction of motion in an image.Thanks in advance.

hello, i'm working the project of detecting image forgeries based on motion bluriness of image. how to find the perceptual blur metric ?? pls help.

You will need to clarify your question. A single image has no time dependance and therfore no motion. Are you comparing a series of images and looking for an object that has changed location between images? Or are you looking for some sort of motion derived blurring in a single image?

Ya I am looking for motion derived blurring in an image and sorry for my unclear question previously.

Is the moving object where the camera is, such that one might hope to study the relative blurring of objects at various angles to the movement of the object?

If so, then is anything known about the optical axis of the moving object relative to the direction of movement?

Is anything known about the focal distances involved? e.g., if the scene is being imaged from behind with an effectively infinite focal length that encompasses the entire scene, then the situation would be different than if the camera is at the moving object and has effectively a spherical shell of focus with anything beyond the limit being naturally out of focus anyhow.
