SummaryEfficient, accurate and robust suite of tools for the future of Computer Vision
Problems AddressedMany image/signal processing tasks can benefit from very accurate registration of two or more images or signals. However, technical and practical challenges have limited the accuracy of current registration methods. Despite widespread potential applications for accurate image registration methods, they are rarely meaningfully used as current algorithms require complex and time-consuming computations, and are not sufficiently accurate. Furthermore, they often fail when no distinguishing features exist in the images.
Applications
TechnologyThe novel registration algorithm can provide very accurate image registration and displacement measurement to less than 0.0002 of a pixel (voxel) close to real time. This translates to a 50x more precise, and 10x faster measurement than existing state-of-the-art algorithms. Low complexity and computation demands of this algorithm allow its integration on low-end and embedded processors. Furthermore, this novel algorithm is robust, being able to measure displacements in images with low-features and poor lighting.
