This setting is used for the value of the -sharpen parameter to ImageMagick. See the description of this parameter, and an explanation of the values it can take (although -sharpen does not take a threshold).

Note that the parameter is only passed to ImageMagick when, for a given image,

perimeter of the thumbnail being generated < ($wgSharpenReductionThreshold × perimeter of the original image)
