Definition. Image smoothing is a technique used in image processing to reduce noise and detail in an image, creating a more uniform appearance.

[2003.07504] Real-time Image Smoothing via Iterative Least Squares

In this paper, we propose a new global optimization based method, named iterative least squares (ILS), for efficient edge-preserving image smoothing.

Smoothing an image - Nilearn

Here we smooth a mean EPI image and plot the result As we vary the smoothing FWHM, note how we decrease the amount of noise, but also lose spatial details.

Smoothing vs. sharpening of colour images: Together or... - Sciendo

Smoothing refers to the case of denoising when noise follows a Gaussian distribution. Both operations, smoothing noise and sharpening, have an opposite nature.

image.smooth function - RDocumentation

Takes an image matrix and applies a kernel smoother to it. Missing values are handled using the Nadaraya/Watson normalization of the kernel.
