- W53586802 abstract "The MPEG-4 algorithm applicable to compression of video-images of the anterior eye segment and JPEG-2000 applicable to compression of static images of the lens and retina under the conditions of mydriasis were used to enable the telemedicine consultations. The compiled compression files were sent to the institute's E-Mail address by means of a voice modem through an analogue telephone line. The pixel structures of non-compression and compression images of the anterior eye segment and lenses were comparatively studied. The deviations of images' optic density versus non-compression images were found to be below or equal to 2.7%, thus, they can be attributed to a static error. The quantitative colorimetry of images was used, on the basis of a software-based color-regulating filter, to determine the lens-nucleus density and cataract-maturity degree. The differences between values of the green-canal brightness were found within the RGB model before and after the application of the filter in the posterior cortical strata and in the anterior lens-nucleus portion, which provided for classifying 6 stages of the lens-nucleus density and cataract maturity." @default.
