Sharpening spatial filters seek to highlight fine detail, remove blurring from images and highlight edges. Sharpening filters are based on spatial differentiation.

Nonlinear spatial filters apply a nonlinear operation to an image. They are used to enhance or extract features from an image in a more complex way than linear filters. Examples include median filters, which are used to remove noise from an image by replacing each pixel with the median value of the pixels in its neighborhood, and morphological filters, which are used to extract specific shapes or structures from an image.

Spatial filtering is a technique used to enhance the image based on the spatial characteristics of the image. It can be used for image sharpening, edge detection, blurring, image sharpening and noise reduction.

Spatial filterimage processing

Linear spatial filters apply a linear operation to an image, such as convolution with a kernel or mask. They are used to enhance or extract features from an image, such as edges or textures such as Sobel and Prewitt, and linear image enhancement techniques, such as histogram equalization.

Neighborhood operations operate on a larger neighborhood of pixels than point operations as discussed in Image Processing #3. They are mostly a square around a central pixel and any size rectangle and any shape filter are possible.
