how to use inkscape to turn image to cartoon

So, for 'Comic Book' effect, I prefer stroking the edges onto the darker side. This effect distorts the eyes of persons. Stroking the edges astride enlarges dark zones of the image. Second experiment (Difference of Gaussians): strokes the edges onto the darker side of the edge locations.First experiment (Sobel): strokes the edges astride the edge locations.The difference between the two experiments was the method of edge detection (as implemented in Gimp). Only the 'value' mode turns these to very light gray. Some difference of colors is turned to blue lines. The third experiment seems (to me) to give the best result. But, it's difficult to find a desaturation method that turns yellow to dark gray.

In the second experiment, some differences of colors is turned into yellow lines.

But, sometimes, limits of objects is visible as a difference of hue. In the first experiment, the desaturation of the image make you to lose some differences of colors. With which experiment do we obtain the edges more easily ?

Colors -> Desaturate -> Desaturate (mode=Value) (compare with other modes).

Third experiment ('Detect, desaturate, invert'): Second experiment ('Detect, invert, desaturate'):

Colors -> Desaturate -> Desaturate (choose the mode you want).

Desaturate the image (you choose the method yourself, try several ones), you can try:.

or using 'Filters -> Edge-Detect -> Edge.(Sobel)'.

The following posts explain the reasons why this method works better (according to me) than :

'Filters -> G'MIC-Qt -> Repair -> Smooth ', multiple times.

On top layer, set 'layer mode' to 'multiply'.

On top layer, 'Colors -> Threshold : about 210-240, 255'.

On top layer, 'Colors -> Desaturate -> Desaturate (mode=Value)'.

On top layer, 'Filters -> Edge-Detect -> Difference of Gaussians (legacy)' (uncheck 'Invert' option).

On top layer, 'Filters -> G'MIC-Qt -> Repair -> Smooth '.

On bottom layer, 'Colors -> Hue-Chroma (lightness=10)'.

On bottom layer, 'Colors -> Saturation (scale=1.8)'.

Reduce the image to about 700px-1000px wide or high.

Warning: It aims to make simple style cartoons (not to make more artistic cartoons). (It's just what I learned during my experiments to turn photos into cartoons.)

plug-ins (except G'MIC 'Repair' filters),.

Here is a very short tutorial about turning a photo into a cartoon picture manually without:
