Sixth Annual Report of the Independent Monitoring Group for A Vision for Change – the Report of the Expert Group on Mental Health Policy – July 2012 This is the 6th Annual Report of the Independent Monitoring Group for A Vision for Change (IMG) and the final report of the Second Group. It is clear to the IMG that the implementation of A Vision for Change (AVFC) to date including 2011 has been slow and inconsistent. There is a continued absence of a National Mental Health Service Directorate with authority and control of resources. Such a body has the potential to give strong corporate leadership and act as a catalyst for change.

This report, the first comprehensive review of mental health policy since 'Planning for the Future' was published in 1984, makes a series of recommendations for the mental health services, including the closure of all psychiatric hospitals and re-investment of the resources into a community-based mental health service.This resource was contributed by The National Documentation Centre on Drug Use.

The key element of the HSE South’s Programme is to enhance and develop community mental health services in Carlow, Kilkenny and South Tipperary, to enable the service user to remain in the community to the greatest extent possible. HSE South has prioritised the implementation of the change programme and has allocated more than €20m capital funding and over €1.75m revenue funding to support this comprehensive development programme. Speaking at the briefings Mr. Pat Healy, Regional Director of Operations, HSE South said, “When this plan is delivered, clients will have access to the highest standards of services in all three counties, which should significantly improve these clients’ treatment programmes and quality of life. The National Service Users Executive are supporting the change programme, which is of immense importance to HSE South. The programme heralds the enhancement and development of community mental health services, the closure of old long stay institutions, the separation of North and South Tipperary acute inpatient mental health services and development of appropriate acute inpatient services, for the extended catchment area, in line with the national strategy for mental health “A Vision for Change”. The programme also acts on recommendations of the Mental Health Commission.”This resource was contributed by The National Documentation Centre on Drug Use.

This paper presents a vision-based localization approach for an underwater robot in a structured environment. The system is based on a coded pattern placed on the bottom of a water tank and an onboard down looking camera. Main features are, absolute and map-based localization, landmark detection and tracking, and real-time computation (12.5 Hz). The proposed system provides three-dimensional position and orientation of the vehicle along with its velocity. Accuracy of the drift-free estimates is very high, allowing them to be used as feedback measures of a velocity-based low-level controller. The paper details the localization algorithm, by showing some graphical results, and the accuracy of the system

This paper presents an automatic vision-based system for UUV station keeping. The vehicle is equipped with a down-looking camera, which provides images of the sea-floor. The station keeping system is based on a feature-based motion detection algorithm, which exploits standard correlation and explicit textural analysis to solve the correspondence problem. A visual map of the area surveyed by the vehicle is constructed to increase the flexibility of the system, allowing the vehicle to position itself when it has lost the reference image. The testing platform is the URIS underwater vehicle. Experimental results demonstrating the behavior of the system on a real environment are presented

This paper describes the improvements achieved in our mosaicking system to assist unmanned underwater vehicle navigation. A major advance has been attained in the processing of images of the ocean floor when light absorption effects are evident. Due to the absorption of natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination for processing underwater images. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion. In this paper a technique to correct non-uniform lighting is proposed. The acquired frames are compensated through a point-by-point division of the image by an estimation of the illumination field. Then, the gray-levels of the obtained image remapped to enhance image contrast. Experiments with real images are presented

This paper deals with the problem of navigation for an unmanned underwater vehicle (UUV) through image mosaicking. It represents a first step towards a real-time vision-based navigation system for a small-class low-cost UUV. We propose a navigation system composed by: (i) an image mosaicking module which provides velocity estimates; and (ii) an extended Kalman filter based on the hydrodynamic equation of motion, previously identified for this particular UUV. The obtained system is able to estimate the position and velocity of the robot. Moreover, it is able to deal with visual occlusions that usually appear when the sea bottom does not have enough visual features to solve the correspondence problem in a certain area of the trajectory

It is well known that image processing requires a huge amount of computation, mainly at low level processing where the algorithms are dealing with a great number of data-pixel. One of the solutions to estimate motions involves detection of the correspondences between two images. For normalised correlation criteria, previous experiments shown that the result is not altered in presence of nonuniform illumination. Usually, hardware for motion estimation has been limited to simple correlation criteria. The main goal of this paper is to propose a VLSI architecture for motion estimation using a matching criteria more complex than Sum of Absolute Differences (SAD) criteria. Today hardware devices provide many facilities for the integration of more and more complex designs as well as the possibility to easily communicate with general purpose processors

We present a computer vision system that associates omnidirectional vision with structured light with the aim of obtaining depth information for a 360 degrees field of view. The approach proposed in this article combines an omnidirectional camera with a panoramic laser projector. The article shows how the sensor is modelled and its accuracy is proved by means of experimental results. The proposed sensor provides useful information for robot navigation applications, pipe inspection, 3D scene modelling etc

In a search for new sensor systems and new methods for underwater vehicle positioning based on visual observation, this paper presents a computer vision system based on coded light projection. 3D information is taken from an underwater scene. This information is used to test obstacle avoidance behaviour. In addition, the main ideas for achieving stabilisation of the vehicle in front of an object are presented

Primary care physicians have to assess visual functions essential for driving when determining medical fitness to drive. However, it can be difficult to apply the legal requirements that are described in annex 1 of the ordinance regulating the admission to road traffic of 1976 (OAC) due to lack of unambiguousness. This article discusses those visual functions that have to be assessed namely visual acuity, the visual field and the detection of diplopia and it presents the appropriate methods for the primary care setting. Another objective is to discuss the relevance of road safety requirements on vision and to present the new Swiss requirements proposed for the future in comparison to some international recommendations.
