Camera intrinsic blur kernel estimation: A reliable framework

2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
This paper presents a reliable non-blind method to measure intrinsic lens blur. We first introduce an accurate camera-scene alignment framework that avoids erroneous homography estimation and camera tone curve estimation. This alignment is used to generate a sharp correspondence of a target pattern captured by the camera.

Designing the optimal convolution kernel for modeling the motion blur

SPIE Proceedings, 2011
Motion blur acts on an image like a two dimensional low pass filter, whose spatial frequency characteristic depends both on the trajectory of the relative motion between the scene and the camera and on the velocity vector variation along it. When motion during exposure is permitted, the conventional, static notions of both the image exposure and the ...

Method to detect and calculate motion blur kernel

SPIE Proceedings, 2010
Motion during camera's exposure time causes image blur, we call it motion blur. According to the linear system theory, if we can find the blur kernel which has the same meaning of point spread function, the blurred image can be restored by the blur kernel using iterative algorithms, such as R-L (Richardson-Lucy).
