Over the past two decades, seal populations around Britain have undergone substantial changes in distribution and abundance. Most of the UK's grey and harbour seals live in Scottish waters, but significant parts of both populations also occur fragmented throughout the Irish Sea (including Wales), the southwest (Cornwall, Scilly Isles, Brittany), Norfolk, Lincolnshire and Northumberland. Ireland also has significant seal populations around its south and west coasts. Tracking studies have shown that seals are quite capable of moving great distances in a matter of days; conversely breeding colonies are characterised by seals that remain faithful to previous breeding sites and even to where they were born. Recent changes in UK seal population trends have focussed attention on the fact that the 'degree of connectedness' between seals in different areas remains unclear. A large amount of data from different areas has been collected on seal populations, using the technique of photo-identification (photo-ID), as seals have unique patterns allowing individuals to be identified. In addition to SMRU photo-ID research, locally based studies of these seal populations have created their own photo-ID catalogues, ranging greatly in number of images, geographic extent and duration of survey. Because of the large number of seals in the population and the large quantity of data collected, computer-aided matching is needed to make useful comparisons. Existing software for matching images doesn't deal with a large number of existing images and new software is required. This project aims to form a network of partners involved in seal photo-ID and update their knowledge and skills in photo-ID through training workshops and web-based resources. New image processing software will be developed to allow inclusion of many old images previously unavailable. Partners will benefit from the increased efficiency of their photo-ID programmes and databases which will in turn inform the science community. There is also the potential for benefits to extend to local economies through ecotourism.

在过去的二十年里，英国周围的海豹种群在分布和数量上发生了实质性的变化。英国的大部分灰海豹和港海豹生活在苏格兰水域，但这两种种群的大部分也分散分布在爱尔兰海（包括威尔士）、西南部（康沃尔、锡利群岛、布列塔尼）、诺福克、林肯郡和诺森伯兰。爱尔兰南部和西部海岸也有大量的海豹。跟踪研究表明，海豹很有能力在几天内移动很远的距离；相反，繁殖群的特点是海豹仍然忠于以前的繁殖地点，甚至是它们出生的地方。最近英国海豹数量趋势的变化将注意力集中在不同地区海豹之间的“联系程度”仍然不清楚这一事实上。利用照片识别技术（photo-ID）从不同地区收集了大量关于海豹种群的数据，因为海豹有独特的图案，可以识别个体。除了SMRU的照片识别研究之外，当地对这些海豹种群的研究也建立了自己的照片识别目录，在图像数量、地理范围和调查时间上都有很大的不同。由于种群中海豹数量众多，收集的数据也很多，因此需要计算机辅助匹配来进行有用的比较。现有的图像匹配软件不能处理大量的现有图像，需要新的软件。该项目旨在通过培训工作坊和网络资源，建立一个参与照片识别的合作伙伴网络，更新他们在照片识别方面的知识和技能。新的图像处理软件将被开发，以允许包括许多以前无法获得的旧图像。合作伙伴将受益于其照片识别程序和数据库效率的提高，这反过来将为科学界提供信息。生态旅游也有可能给当地经济带来好处。
