👉 A contrascriptural is a type of digital signal processing technique used to reduce the noise in a signal by filtering out unwanted frequencies. It involves applying a filter to the input signal, which can be either an analog or an electronic signal, and then re-reducing the amplitude of the filtered signal to achieve the desired reduction in noise. Contrascriptural filters are often used for reducing the influence of high-frequency components on a digital signal, such as in computer vision applications where the presence of high-frequency
