An algorithm for image registration and mosaicing on underwater sonar image sequences characterised by a high noise level, inhomogeneous illumination and low frame rate is presented. Imaging geometry of acoustic cameras is significantly different from that of pinhole cameras. For a planar surface viewed through a pinhole camera undergoing translational and(More)
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(More)
This paper presents an algorithm for image registration and mosaicing on video sequences acquired by an underwater acoustic camera. The sonar images of our interest can be characterized by a high noise level, inhomogeneous illumination and low frame rate. Imaging geometry of acoustic cameras is significantly different from that of pinhole cameras. For a(More)
In our previous work, we proposed a two-step procedure by using an infinite slab spectral geometry to capture the strong core/reflector spectral interaction in the pebble bed reactor core analysis and we demonstrated the validity of the two-step procedure against a homogeneous PBMR-400 problem. On the other hand, we also proposed Equivalent Cylinder Fuel(More)
