Is the Sobel operator a linear filter?
What are some other types of image filters?
There are many types of image filters, such as Gaussian blur, median filter, and Laplacian of Gaussian filter, to name a few. Each filter has its own strengths and limitations and may be used for different purposes depending on the application. For example, a Gaussian blur filter can be used to reduce noise and smooth out an image, while a Laplacian of Gaussian filter can be used to detect edges and other features.
