In this work, we investigate the relation between the edge profiles present in a motion blurred image and the underlying camera motion responsible for causing the motion blur. While related works on camera motion estimation (CME) rely on the strong assumption of space-invariant blur, we handle the challenging case of general camera motion. We first show how edge profiles alone can be harnessed to...
We propose a framework for robust estimation of normal of a planar scene from a single motion blurred observation. We first reveal how feature points can be extracted from blur kernels and matched to generate several point correspondences. Although these points correspond to different homographies, the fact that they conform to the same normal yields a rank-3 constraint which we harness within a hierarchical...
Integrity verification is verifying the originality of an object. A number of robust and secure image hashing methods are existing in literature, which are suited for integrity verification of images. However, a complete system for integrity verification which clearly distinguishes between acceptable and malicious manipulations is still in research. This paper presents a complete system for integrity...
