An intelligent vision-based system for detecting self-harm behavior

在惩教场所，自残是一种常见的死亡原因。持续监测和快速发现**自残事件对于保护囚犯的生命和降低死亡率至关重要。在过去的几十年里，已经开发了几种技术来防止监狱中的自杀企图。然而，他们中的大多数**使用笨重的设备和/或在很大程度上依赖于人类的守卫关注和干预。我们的**目标是开发自主视频监控解决方案，以便智能地检测监狱中危及生命的事件，并允许快速和反应的干预。拟议的系统将被设计为**在现实条件下持续运行，以检测通过上吊或割腕自杀的企图；2-*两名囚犯之间的打斗；3-以及危及生命的情况的症状。这些目标将通过确保**有效地利用视觉获取技术、计算机视觉方法和**人工智能方面的最新进展来实现。该项目将带来智能视频监控领域的新知识**，同时有助于培训高素质的人员，这些人员将在**加拿大获得高需求的专业知识。我们的工作还将允许我们的工业合作伙伴开发一种商业产品，用于**惩教服务。预计这一产品的影响将不仅仅是经济上的。这将有助于**拯救处于危险中的被监禁者的生命，并避免由此带来的痛苦。

Self-harm is a common cause of death in correctional settings. The constant monitoring and the rapid detection**of self-harm events are crucial for protecting inmates' lives and reducing the mortality rates. During the last**decades, several technologies have been developed for preventing suicide attempts in prisons. However, most**of them use cumbersome devices and/or are greatly depending on human guard attention and intervention. Our**objective is to develop autonomous video surveillance solutions in order to intelligently detect life-threatening**events in prisons, and allow a rapid and reactive intervention. The proposed system will be designed to operate**continuously in realistic conditions to detect suicide attempts by hanging or by wrist cutting; 2- fights between**two inmates; 3- and symptoms of life threatening situations. These objectives will be achieved by ensuring the**efficient exploitation of recent advances in visual acquisition technologies, computer vision methods and**artificial intelligence. This project will lead to new knowledge in the intelligent video surveillance domain,**while contributing to training highly qualified personnel who will acquire an expertise in high demand across**Canada. Our work will also allow our industrial partner to develop a commercial product to be deployed in**correctional services. The impact of this product is expected to be more than merely economic. It will help**saving the lives of incarcerated people at risk, and avoid the resulting suffering.
