Two dimensional (2D) radar coincidence imaging is an instantaneous imaging technique which can obtain 2D focused highresolution images using a single pulse without the limitation to the target relative motions. This paper extends the imaging method to three dimensions. Such a three-dimensional (3D) radar imaging technique does not rely on Doppler frequency for resolution and has an extremely sh...

Photon-counting integral imaging has been introduced recently, and its applications in three-dimensional (3D) object sensing, visualization, recognition, and classification under photon-starved conditions have been demonstrated. This paper sheds light on the underlying information-theoretic foundation behind the ability of photon-counting integral imaging in performing complex tasks with far fe...

|This paper addresses the problem of segmenting 3D acoustic images for object recognition purposes. For remotely operated vehicle (ROV) navigation the 3D surroundings have to be understood. Sensors, such as 3D acoustic imaging sensors, can be used for this purpose. Automatic segmentation and reconstruction of an underwater scene could make many underwater operations more e ective and reliable. ...
