What is Image space method?

The Image Space Method is a technique used in computer graphics and computer vision for rendering and analyzing images based on their pixel values. It involves manipulating the image directly in its pixel representation, allowing for operations such as filtering, enhancement, and segmentation. By focusing on the pixels and their intensity values, this method facilitates various image processing tasks without requiring complex mathematical models of the scene geometry. It is often contrasted with object space methods, which deal with the geometric representation of objects in a scene.
