TL;DR: The first results are presented of a research project that aims to investigate the possibility of using active optical techniques for the whole-field 3D reconstructions in an underwater environment, based on the projection of structured lighting patterns acquired by a stereo vision system.

TL;DR: This work has compared in water two 3D imaging techniques based on active and passive approaches, respectively, and whole-field acquisition, and evaluated their capability to acquire 3D points in presence of turbidity.

TL;DR: This work presents the first proposal for color correction of underwater images by using lαβ color space, where the chromatic components are changed moving their distributions around the white point and histogram cutoff and stretching of the luminance component is performed to improve image contrast.

TL;DR: A system to process multispectral scans of double-sided documents that can co-register any number of recto and verso channel maps, and reduce the bleed-through/show-through distortions by exploiting blind source separation, and is able to recover the original colors, thus improving the readability of a document while maintaining its original appearance.

TL;DR: A multi-sensor registration for the automatic integration of 3D data acquired from a stereovision system and a 3D acoustic camera in close-range acquisition is presented and the effectiveness of the method has been demonstrated in this first experimentation of the proposed 3D opto-acoustic camera.
