Webb7 apr. 2024 · Diabetic retinopathy (DR) is a complication of diabetes that affects the eyes. It occurs when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Therefore, there is a need to detect DR in the early stages to reduce the risk of blindness. Transfer learning is a machine learning … WebbA classic peak detection approach in signal processing is as follows: Filter the signal to some reasonable reasonable range, depending on sampling rate and signal properties, e.g. for ECG, an IIR bandpass filter @0.5-20Hz, a zero-phase filter will ensure that no phase shift (and associated time lag) is introduced
