This document describes a distance measurement system for underwater applications with computervision and an Artificial Neural Network (ANN). The developed system is installed in the observation class remotely operated vehicle (ROV) VISOR3, to be used in experimental testing. An integrated camera with two laser pointers are used to obtain input data to a Multi-Layer Perceptron (MLP) ANN, trained with a resilient backpropagation algorithm (RPROP). The solution described in this paper is an alternative to other methods found in the literature. Experimental results are presented.

Catadioptric sensors are used in mobile robot localization because of their panoramic field of view. However most of the existing systems require a constant orientation of the camera and a planar motion, and thus the localization cannot be achieved in general for persons handling a camera. In this paper, we use the images of the vertical lines of indoor environment to localize in realtime the central catadioptric camera orientation and the 2D position. The pose detection is done in two steps. First, a two axes absolute rotation is computed to bring the vertical line images in vertical position on the viewing sphere. Then the 2D pose is estimated using a 2D map of the site.

Underwater robots have had a significant contribution in the inspection, maintenance and repair of underwater structures related to the power and oil industry. Underwater robots have a big potential application in Mexico due to, the two federal Mexican companies related with the power and oil are in constant expansion. CIDESI is working in two projects (Shadow water ROV and Deep water ROV) related to visual inspection ROVs applied to the power and oil industries. Visual inspection is the essential application for a ROV, and it is used into the tasks;underwater structure inspection (dams included), underwater oil production system inspection and underwater pipeline inspection. This applied research paper firstly gives a brief instruction of the two Mexican companies related with the power and oil. Subsequently a description of the objectives and main characteristics of the developed hallow and deep water ROVs are presented and finally a general conclusions and future work is listed.

We present an approach for detection of isolated Caenohabditis Elegans nematodes in clutter environments. The method is based on shape feature histograms which describe the distribution of features of second-order derivative responses of linear image structures. The shape features are able to distinguish isolated from overlapping nematodes and clutter, thereby improving the automated image analysis of nematode populations where accurate assessment of shape is needed. An evaluation is performed on a database of manually segmented images. Shape continuity features proved to have the highest discriminative power. This is consistent with the morphological structure of this kind of organism. Our experiments suggest that similar techniques can be used for identification of other linear shaped biological objects.
