摘要： A method is proposed for automatically locating the optic disc or the optic cup in an image of the rear of an eye. A portion of the image containing the optic disc or optic cup is divided into sub-regions using a clustering algorithm. Biologically inspired features, and optionally other features, are obtained for each of the sub-regions. An adaptive model uses the features to generate data indicative of whether each sub-region is within or outside the optic disc or optic cup. The result is then smoothed, to form an estimate of the position of the optic disc or optic cup.

摘要翻译： 提出了一种用于将视盘或视杯自动定位在眼后方的图像中的方法。 使用聚类算法将包含视盘或视杯的图像的一部分划分成子区域。 为每个子区域获得生物启发特征，以及可选的其他特征。 自适应模型使用特征来产生指示每个子区域是否在视盘或视觉杯内或外的数据。 然后将结果平滑，以形成视盘或视杯的位置的估计。

摘要： A method is proposed for automatically analysing a retina image, to identify the presence of drusen which is indicative of age-related macular degeneration. The method proposes dividing a region of interest including the macula centre into patches, obtaining a local descriptor of each of the patches, reducing the dimensionality of the local descriptor by comparing the local descriptor to a tree-like clustering model and obtaining transformed data indicating the identity of the cluster. The transformed data is fed into an adaptive model which generates data indicative of the presence of drusen in the retinal image. Furthermore, the trans formed data can be used to obtain the location of the drusen within the image.
摘要翻译： 提出一种自动分析视网膜图像的方法，以确定指示年龄相关性黄斑变性的玻璃疣的存在。 该方法提出将包括黄斑中心的感兴趣区域划分为斑块，获得每个斑块的局部描述符，通过将本地描述符与树状聚类模型进行比较来获得局部描述符的维度，并获得指示 集群的身份。 将变换的数据馈送到自适应模型，其生成指示视网膜图像中玻璃疣的存在的数据。 此外，反式形成的数据可以用于获得图像中的玻璃疣的位置。
