13. the resulting values are scaled after computation using this Maximum Disparity value If you are unsure what to set just use the default setting which will do for most scenarios The Disparity Scaling control allows scaling the disparity after computation This can be used to strengthen or to weaken the resulting 3D effect The value is given in percent so a setting of 100 leaves the result untouched For further information on disparity scaling and output refer to section 6 The Disparity Options tab offers three different filters which can be used to filter the resulting depth or disparity image 1 The Smoothing filter can be used to smooth the resulting image to get rid of errors 2 The Diffusion Filter is a border preserving filter which enhances the resulting depth image at object borders 3 The Color Aware Filter is also a border preserving filter which respects color borders in the input images while strengthening the object borders in the depth map It is recommended to turn on smoothing and diffusion filters To enhance the results you can also try to turn off the diffusion filter and use the color aware filter instead The Quality slider offers three predefined quality levels Low is only recommended for previews as the results will be poor but the computation is fast The recommended setting is Medium as this produces good results with good computation times The High s
