"WebThe OPTICS algorithm. A case is selected, and its core distance (ϵ′) is measured. The reachability distance is calculated between this case and all the cases inside this case’s maximum search distance (ϵ). The processing order of the dataset is updated such that the nearest case is visited next. " - Optics algorithm wikipedia

WebMar 9, 2024 · Optical coherence tomography angiography (OCT-A) has emerged as a non-invasive technique for imaging the microvasculature of the retina and the choroid. The first clinical studies using this innovative technology were published in 2014 . [1] Although it is theoretically somewhat complex, the method of generalized projections has proven to be an extremely reliable method for retrieving pulses from FROG traces. Unfortunately, its sophistication is the source of some misunderstanding and mistrust from scientists in the optics community. Hence, this section will attempt to give some insight into the basic philosophy and implementation of the method, if not its detailed workings.
