Abstract:<\/strong><\/p>\n

In this project, we want to investigate fundamental research questions in the field of postoperative analysis of ophthalmic surgery<\/a> (i.e. concerned with the human eye) videos (OSVs). More precisely, three research objectives are covered: (1) Classification of OSV segments<\/b> \u2013 is it possible to improve upon the state-of-the-art in automatic content classification and content segmentation of OSVs, focusing on regular and irregular operation phases? (2) Relevance prediction and relevance-driven compression<\/b> \u2013 how accurately can the relevance of OSV segments be determined automatically for educational, scientific, and documentary purposes (as medical experts would do), and what compression efficiency can be achieved for OSVs when considering relevance as an additional modality? (3) Analysis of common irregularities in OSVs for medical research<\/b> \u2013 we address three quantitative medical research questions related to cataract surgeries, such as: is there a statistically significant difference in duration or complication rate between cataract surgeries showing intraoperative pupil reactions and those showing no such pupil reactions?<\/p>\n

We plan to perform these investigations using data acquisition, data modelling, video content analysis, statistical analysis, and state-of-the-art machine learning methods \u2013 such as content classifiers based on deep learning. The proposed methods will be evaluated on annotated video datasets (\u201cground truth\u201d) created by medical field experts during the project.<\/p>\n

Beyond developing novel methods for solving the abovementioned research problems, project results are expected to have innovative effects in the emerging interdisciplinary field of automatic video-based analysis of ophthalmic surgeries. In particular, research results of this project will enable efficient permanent video documentation of ophthalmic surgeries, allowing to create OSV datasets relevant for medical education, training, and research. Moreover, archives of relevant OSVs will enable novel postoperative analysis methods for medical research questions \u2013 such as causes for irregular operation phases, for example.<\/p>\n

The research project will be a cooperation between computer scientists of AAU Klagenfurt (conducted by Prof. Klaus Sch\u00f6ffmann, supported and advised by Dr. Mario Taschwer and Prof. Laszlo B\u00f6sz\u00f6rmenyi) and ophthalmic surgeons and researchers at Klinikum Klagenfurt (Dr. Doris Putzgruber-Adamitsch, Dr. Stephanie Sarny, Prof. Yosuf El-Shabrawi).<\/p>\n","protected":false},"excerpt":{"rendered":"
