             abstract = "Multi-frame super-resolution is possible when there is motion and 
                         non-redundant information from a sequence of low-resolution input 
                         images. Remote sensors, surveillance videos and modern mobile 
                         phones are examples of devices able to easily gather multiple 
                         images of a same scene. However, combining a large number of 
                         frames into a higher resolution image may not be computationally 
                         feasible by complex super-resolution techniques. We discuss herein 
                         a set of simple and effective high-performance algorithms to 
                         fastly super-resolve several low-resolution images in an always-on 
                         low-power environment, with possible applications in mobile 
                         computing, forensics, and biometrics. The algorithms rely on 
                         geometric k-nearest neighbors to decide which information to 
                         consider in each high-resolution pixel, have a low memory 
                         footprint and run in linear time as we increase the number of 
                         low-resolution input images. Finally, we suggest a minimum number 
                         of input images for multi-frame super-resolution, considering that 
                         we expect a good response as fast as possible.",
