The MAD of the image is a robust statistical scheme and was previously used to tune image filter
based on the gradient of the noisy image .
(2) For intensity (illumination) layer, estimating the illumination component with guided image filter
in gradient domain, followed by extracting the reflection component
Guided Image Filter
. GIF filters the input image by considering the guidance image.
The characterization was primarily carried out using a JEOL 3010 high resolution electron microscope (JEOL, Peabody, MA), equipped with a Gatan Image Filter
(with parallel EELS) and a light element EDS system.

The guided filter which is a local-based image filter
has the potential to minimize the overlap spatial detail information between the intensity information (INT) and PANI.
The power of box filtering is one can write a general image filter
that can do sharpen, emboss, edge-detect, smooth, motion-blur, etcetera.
Kamei, "Image filter
design for fingerprint enhancement," in N.
In this paper, we proposed a hardware-in-the-loop (HIL) simulation based evolutionary design method of image filter
. The EA runs in MATLAB/Simulink, while the fitness evaluation which is the most time consuming part, is implemented on hardware.
Sato's  group proposed a 3D multiscale liner image filter
to extract the critical property in medical images.
Wales had earlier made a call for the foundation to implement a personal image filter
in May 2011 and the Board of Trustees unanimously voted 10-0 in favor of the filter.
Finally, the guided image filter
is used to eliminate the blocking artifacts induced by the dark channel and remove the halos caused by the DT-CWT, while preserving the edge information of the original image.
