Web1 Apr 2024 · SciPy in Python. SciPy in Python is an open-source library used for solving mathematical, scientific, engineering, and technical problems. It allows users to manipulate the data and visualize the data using a wide range of high-level Python commands. SciPy is built on the Python NumPy extention. SciPy is also pronounced as “Sigh Pi.”. WebBlurring is widely used to reduce the noise in the image. We can perform a filter operation and see the change in the image. Let us consider the following example. from scipy import misc face = misc.face() …
