Other edge-preserving smoothing filters include: anisotropic diffusion, weighted least squares, edge-avoiding wavelets, geodesic editing, guided filtering, iterative guided filtering and domain transforms. 
The bilateral filter has been shown to be an application of the short time kernel of the Beltrami flow that was introduced as an edge preserving selective smoothing mechanism before the bilateral filter. Ī simple trick to efficiently implement a bilateral filter is to exploit Poisson-disk subsampling.

The free G'MIC plugin Repair → Smooth for GIMP adds more control. GIMP implements a bilateral filter in its Filters → Blur tools and it is called Selective Gaussian Blur. Alternative filters, like the guided filter, have also been proposed as an efficient alternative without these limitations.Īdobe Photoshop implements a bilateral filter in its surface blur tool. There exist several extensions to the filter that deal with these artifacts, like the scaled bilateral filter that uses downscaled image for computing the weights.
Gradient reversal – introduction of false edges in the image. Staircase effect – intensity plateaus that lead to images appearing like cartoons. The bilateral filter in its direct form can introduce several types of image artifacts: As the spatial parameter σ d increases, the larger features get smoothened. As the range parameter σ r increases, the bilateral filter gradually approaches Gaussian convolution more closely because the range Gaussian widens and flattens, which means that it becomes nearly constant over the intensity interval of the image. There are only a couple of minor drawbacks to FotoSketcher Portable: it only works with JPG and BMP files, and if you add a text caption to the image, you won't be able to see it on the preview window.Īpply a sketch effect to your photos in no time.The bilateral filter is defined as I filtered ( x ) = 1 W p ∑ x i ∈ Ω I ( x i ) f r ( ‖ I ( x i ) − I ( x ) ‖ ) g s ( ‖ x i − x ‖ ). #USING EDGE INTENSITY IN PHOTOSKETCHER PORTABLE#
FotoSketcher Portable applies the sketch effect in just a few seconds, and the result will be displayed side to side to the original picture, which is great for comparison FotoSketcher Portable also lets you add a text caption and embellish your sketch with a frame.
