The following are some of the top Python libraries that make building image processing projects very convenient. OpenCV is hands down the most popular and widely used Python library for vision tasks such as image processing and object and face detection. The conversation over Python image processing libraries is incomplete without Sci-Kit Image. It is a simple and straightforward library that can be used for any computer vision task. SciPy is majorly used for mathematical computations but it is also capable of performing image processing. Face Detection, Convolution, and Image Segmentation are some of the features provided by SciPy.
