Having said that, you can do whatever you want with images, as they are matrices containing numbers! ## Mathematical Tools in Image Processing Mathematical tools are indispensable in digital image processing. Set theory, for instance, is crucial for understanding and performing operations on images, particularly binary images. In these images, pixels are typically categorized as either foreground (1) or background (0). In set theory, operations such as union and intersection determine relationships between features represented by pixel coordinates. Intensity transformations and spatial filtering are other mathematical tools. They focus on manipulating pixel values within an image, where operators are applied to single images or a set of images for various purposes, like noise reduction.
