1. neon

Neon effect.

Parameters:

Name Type Minimum value Maximum value Default value Description
brush_radius float 0 20 3 Neon glow radius. The more is this value, the thicker are the edges (the image looks more glowing).
amount float 0 1 0.2 This parameter determines how detailed the resulting image will look. The more is this value, the more glowing the image looks.

3. cartoon

This filter turns a photo into a cartoon-like image.

Parameters:

Name Type Minimum value Maximum value Default value Description
quant_levels int 1 100 4 The number of quantization levels. The more is this value, the more 'sub-colors' each color will have.
use_anisotropic bool     FALSE If the value is true, anisotropic DoG filter (http://en.wikipedia.org/wiki/Difference_of_Gaussians) will be used to track outlines. It makes the edges look different.
use_fd bool FALSE If this value is true, face detection is performed. The found face is used to adjust the median_cut algorithm settings (this algorithm works if use_median_cut = true.) If a face is not found, then the image is processed without the use_median_cut algorithm.
use_median_cut bool TRUE If this value is true, and use_fd=true, quantization level search through median cut method is performed. This results in better defined and sharper edges between color areas.
fill_solid_color bool FALSE If this value is true, all image areas (except for the outlines) are filled with a solid color. This color is determined by the target_color parameter.
target_color RGB (128,128,128) The color that is used to filll the image if fill_solid_color = true.
use_warping bool TRUE If this value is false, the edges are not smoothed.
border_strength float 1  20 1 Edge diffusion. The more is this value, the more defined and clear the edges look.
border_width float 0 7 0 Edge thickness. The more is this value, the thicker are the edges.
border_density float 1 5 1 This value defines how many edges there will be in a resulting image. The more is this value, the less edges there will be.
use_color_borders bool   FALSE If this value is true, the edges will be colored (not black). The edge color will not be solid and will depend on the colors in the image.
border_color RGB   (0,0,0) Edge color.
color_intensity float 0 1 0.5 Intensity of color edges. The more is this value, the darker are the edges.
bilateral int 1 100 5 The number of iterations of the bilateral filter (http://en.wikipedia.org/wiki/Bilateral_filter). The more is this value, the smoother are the color areas. Also, the more is this value, the longer it takes to process an image.
bilateral_rad int 1 100 30 Bilateral filter radius. The more is this value, the smoother are the transitions between colors.
bilateral_search int 1 100 5 The more is this value, the less edges there will be in the image. Also, the more is this value, the longer it takes to process an image.
bilateral_complexity bool     FALSE This parameter defines whether a complex (full-featured) bilateral filter will be used in all color channels. This value is false by default, which means that a simplified filter will be used for all color channels. In this case the quality of resulting cartoons will be a little bit lower, but big size images will be processed much faster.
displacement float 0 20 5 This parameter determines how close color areas are to the edges. The more is this value, the closer are color areas to the edges.
radius int 1 100 5  
use_hsv bool     TRUE If this value is true, the image is processed in the HSV color space. If this value is false and use_hsl=true, the image is processed in the HSL color space. If both values are false, the image is processed in the LAB color space. In case both values are true, the image is processed in the HSV color space.
use_hsl bool     FALSE See commentary to the use_hsv parameter.
resize_to int 0 1000 0 Linear size used for preliminary image resizing (the image is downsized to the specified size before processing, then it is upsized back to the original size). If the value is 0, the image is not resized.
