Interest point detection on incomplete images

Use of incomplete image data has become a prominent research issue in recent years, driven by the development of space variant image sensors. Whilst image reconstruction techniques have been developed that enable the subsequent use of standard image processing algorithms, the development of image processing algorithms that can be applied directly to incomplete image data has received less attention. The problem of interest point detection for incomplete images is addressed by presenting an algorithm that can be applied directly to incomplete image data without the requirement of image reconstruction, and the accurate performance of the algorithm is illustrated through visual results and ROC curves.
