The paper presents an overview of image analysis activities of the Brno DAR group in the medical application area of retinal imaging. Particularly, illumination correction and SNR enhancement by registered averaging as preprocessing steps are briefly described; further mono- and multimodal registration methods developed for specific types of ophthalmological images, and methods for segmentation of optical disc, retinal vessel tree and autofluorescence areas are presented. Finally, the designed methods for neural fibre layer detection and evaluation on retinal images, utilising different combined texture analysis approaches and several types of classifiers, are shown. The results in all the areas are shortly commented on at the respective sections. In order to emphasise methodological aspects, the methods and results are ordered according to consequential phases of processing rather then divided according to individual medical applications.
The paper is concerned with a small group of anonymous treatises, located together in the Ms. 524 of the Corpus Christi College Library in Cambridge on fol. 112r to 131v. How these treatises are connected together through their common structure and subject matter and how they create one consistent group is examined. Particular attention is paid to the brief treatise Effectus adventus Domini (On the Effects of the Entry of the Lord <into the Soul>), which is remarkable for its elaborate structure and colourful narrative of the individual effects. The treatise is compared with similar texts as well and an edition of the treatise is provided at the end of the paper. and Jan Odstrčilík.
