Non-iterative construction of super-resolution image from an acoustic camera video sequence
The low visibility condition of underwater environments is often a limiting factor in the exploration of rivers or coastal areas. In such situations, relatively high resolution images produced by an acoustic camera can be an informative measure for the detection of terrain and objects. In this paper, we present a non-iterative super-resolution algorithm for the construction of a high resolution image from multiple frames of acoustic camera images. We discuss the geometry of insonification and image acquisition of an acoustic camera, and describe the detailed procedures for the registration, insonification correction, and fusion
