In this chapter, we study the needs of digital home photo albums and the different components that are required to provide effective and efficient computer-based tools to match the users' expectations for such systems. We focus mainly on indexing and retrieval of photographic images using symbolic descriptions of image contents. We describe how symbolic(More)
Cataract remains a leading cause for blindness worldwide. Cataract diagnosis via human grading is subjective and time-consuming. Several methods of automatic grading are currently available, but each of them suffers from some drawbacks. In this paper, a new approach for automatic detection based on texture and intensity analysis is proposed to address the(More)
Cataract is one of the leading causes of blindness worldwide. A computer-aided approach to assess nuclear cataract automatically and objectively is proposed in this paper. An enhanced Active Shape Model (ASM) is investigated to extract robust lens contour from slit-lamp images. The mean intensity in the lens area, the color information on the central(More)
PURPOSE To validate a new computer-aided diagnosis (CAD) imaging program for the assessment of nuclear lens opacity. METHODS Slit-lamp lens photographs from the Singapore Malay Eye Study (SiMES) were graded using both the CAD imaging program and manual assessment method by a trained grader using the Wisconsin Cataract Grading System. Cataract was(More)
