public Float getMaxPixelThreshold() {
        return this.maxPixelThreshold;
    }
<p>
A threshold used to determine the maximum luminance value for a pixel to be considered black. In a full color
range video, luminance values range from 0-255. A pixel value of 0 is pure black, and the most strict filter. The
maximum black pixel value is computed as follows: max_black_pixel_value = minimum_luminance + MaxPixelThreshold
*luminance_range.
</p>
<p>
For example, for a full range video with BlackPixelThreshold = 0.1, max_black_pixel_value is 0 + 0.1 * (255-0) =
25.5.
</p>
<p>
The default value of MaxPixelThreshold is 0.2, which maps to a max_black_pixel_value of 51 for a full range
video. You can lower this threshold to be more strict on black levels.
