The basic configuration of Single local Adaptive Window Spatial Noise Reducer is based on a preliminary de-noising low-pass filter followed by homogenous region segmentation to the considered pixel in a given local window. The devices are for implanting fluidic material in a patient’s eye and comprise a nozzle and a housing having a slide and a bellows. The neural network iteratively updates a prediction model of the drilling operations and provides recommendations for drilling corrections to a drilling operator.
