Power Matte is an easy to use interactive image matting tool capable of extracting almost any object in an image–even if you are dealing with fine hair detail, smoke, or reflections. This extraction process creates what is known as a matte–essentially a black and white cutout. White matte areas are extracted, black areas not, and gray areas in between represent a level of transparency. Once a matte is extracted, the foreground object can be seamlessly composed onto a new background as well as apply filter and image corrections only within the area defined by the matte. All this is made possible without the aid of blue or green screen photography.
To work this magic, Power Matte iteratively estimates the transparency value for every pixel in the image, based on a small sample of foreground (what you want to cut out) and background (what you want to get rid of), marked by defining simple open or closed masks. Results show that compared with previous approaches, our method is more efficient and requires minimal effort to extract high quality mattes for foregrounds with significant semi-transparent regions. In addition, the foreground edge colors can be estimated in the semi-transparent areas to create a seamless composite. What was once thought of as the Holy Grail of digital imaging is now a reality with Power Matte.
After intense research and development, we’ve created an enhanced rendering algorithm coupled with multiprocessor acceleration for Power Matte v2 to allow it to render incredibly faster using far less memory. This means that you can matte much larger images at much faster speeds than before. Just how fast are we talking about? Using a 2048 x 1556 pixel image on an Intel Quad Core CPU (Q6700) running at 2.66GHz, the previous version of Power Matte would process the matte in 2:42 minutes. Power Matte v2 now processes the same matte in 6.4 seconds using 5 times less memory.
Power Matte is based on unpublished research and technology by Jue Wang from the University of Washington and is available for download or purchase at: www.digitalfilmtools.com for $245. Upgrade pricing is available for existing customers.
