Random Image Filter and Grayscale Conversion

This function loads an image from a specified path, applies a random image filter from the Pillow library's ImageFilter module, converts the image to grayscale, and saves the processed image to the output path.

Technology Stack : Pillow library, ImageFilter module, ImageOps module

Code Type : Image processing
