             <comment><![CDATA[How bright (<code>R+G+B</code>) does a pixel need to be in order to be recognized as a light source?<br/>
             Increasing this threshold requires brighter light sources (i.e. more white or less color, respectively) but prevents some «false alarms» where semi-bright parts, e.g. hands where colors can change quite a lot compared to the background, are incorrectly recognized as light source.]]></comment>

             <comment><![CDATA[How much does the strongest color channel of a pixel have to change, compared to the background image (<code>max(dR, dG, dB)</code>), in order to be recognized as light source? <br/>
             Increasing this threshold makes it harder for light sources to be accepted on bright backgrounds, but decreases the danger of noise or generally bright spots counting as light source.]]></comment>

             Raising this value might, in some cases, avoid that some light objects lit by the light source are added to the light mask.]]></comment>

             <comment><![CDATA[Determines how the effect tries to adapt to background changes. <br/>
             The Light Graffiti remembers the first frame of the clip it is applied to, so the clip should <em>always</em> start with the painter outside of the video. If the background constantly changes, e.g. on a street, try to set α > 0 to calculate an average background image.]]></comment>
