What is Blurring and Smoothing? Blurring or smoothing is a fundamental image processing technique that involves reducing the detail and noise in an image. It works by averaging or filtering the pixel value in a neighborhood around each pixel to produce a softer, less detailed picture. In Python, especially using libraries like OpenCV, blurring is …

What is NumPy? NumPy is a Python library for arrays. It also has functions for working in algebra, Fourier transforms, and matrices. Travis Oliphant created NumPy in 2005. It is an open-source project, and you can use it freely. It stands for Numerical Python. NP is a Python library written partially in Python, but most …
Now we’ll explore how Canny Edge Detection works and implement it using Python with OpenCV.Edge detection is a fundamental technique in image processing and Computer Vision, used to identify the boundaries of objects within an image. Canny Edge Detection stands out as one of the most robust and widely used techniques among the various edge …
