12,13. In the Australian study the change from visual impairment with PVA (<20/40 in the better-vision eye) to no visual impairment with BCVA (≥20/40 in the better vision eye) was found in 7.5% participants 49 years of age and older11. In Mexican-...

One of the most time-consuming and challenging assessments is distinguishing between natural variation versus change in the disease state that might warrant changes in the treatment plan. Such evaluations often require meticulously comparing current and historical imaging side by side and can be highly ...
Breaking change: The personZoneEvent event has been renamed to personZoneEnterExitEvent. This event is raised by the personcrossingpolygon operation when a person enters or exits the zone and provides directional info with the numbered side of the zone that was crossed. Video URL can be provided...
This change in focal length of the lens from about 1.5 cm to 1.25cm represents an increase in power from 66 dioptres to about 80 dioptres. The nearest point which can be focused by the eye is about 10 cm distance in a young adult, but as the lens becomes less elastic with age, ...
This is WIP and may change significantly... feedback welcome. Model creation throws error if pretrained=True and no weights exist (instead of continuing with random initialization) Fix regression with inception / nasnet TF sourced weights with 1001 classes in original classifiers bitsandbytes (https...
Prototype of set_input_size() added to vit and swin v1/v2 models to allow changing image size, patch size, window size after model creation. Improved support in swin for different size handling, in addition to set_input_size, always_partition and strict_img_size args have been added to ...
Neovascular age-related macular degeneration (nAMD) is one of the major causes of irreversible blindness and is characterized by accumulations of different lesions inside the retina. AMD biomarkers enable experts to grade the AMD and could be used for th
by quantifying the change in motion aftereffect that arises when chromatic modulation is added to a luminance-defined adapting display19,20. Determining CEq is possible only when the two colour components of the colour stimulus appear to have equal brightness (or are equi-bright). For CVn and ...
