Denoiser takes out film grain noises and camera noises from a sequence of 10 bit DPX files and 8 bit TIFF files using very powerful motion estimation algorithm using adjacent multiple frames. The unique feature of Zaxel Denoiser is noise reduction with affine transformation. When the camera is panning in the scene, it is difficult to obtain motion estimation. Zaxel's unique affine transformation can detect motion motion vectors even in the presence of camera motions. Many customers are praising Zaxel Denoiser saying that they have never found a better noise reduction software in the last 5 years.
Superscaler upconverts 10 bit DPX files and 8 bit TIFF files to 4K and 8K with super resolution algorithm. Zaxel's super resolution algorithm can take advantage of motion vector to identify objects so that resulting images can reveal more information than the originals.
Debander takes out contours, or Mach bands, generated by 8 bit image processing or compression artifacts. This processing is necessary for restoring old movies and compressed Blu-ray movies.
Color Convergence is a common problem with high end 4k and 8k resolution projectors. This is a fundamental technical issue created by the use of RGB overlapping images in the projector itself. As the distance from projector to screen increases, the small offsets between projector color bands leads to prominent color defects.
Installations with overlapping projectors (3D) or uniquely shaped screens encounter this issue immediately, but it subtlety affects the quality of any digital projection onto a large screen.
Zaxel has created a GPU based solution to the Color Convergence problem and integrated it into our Zaxtar 5 4K 60P video server.
Our solution is a two step process. The initial phase calibrates a software map that is specific to the projector and screen. Users manipulate points on a graphic mesh to align projection color bands on a sub-pixel level. This calibration is saved to the server and does not need to be modified after initial installation.
The second stage is a real-time graphics remapping integrated in our high resolution playback server. This applies the sub-pixel transformations to uncompressed video at 60P.
