YUVsoft announced a new tool in 2D to 3D Suite and Stereo Processing Suite called "Depth Upscale". Depth or disparity maps are frequently created in a lower resolution than input 2D video, and they should be upscaled back to the full resolution before stereo generation. Depth Upscale provides much more accurate edges than usual image resizing algorithms.

Sometimes it's more convenient to create a depth map in less than the original high resolution, such as half or even lower resolution. Creating a depth map in full HD may take a long time, and in some cases such accuracy is unnecessary. Occasionally, drawing a depth map in a low resolution, but with greater detail, is more beneficial than spending the same amount of time making a depth map in the original high resolution. In such cases, time or budget limitations may require you to specify fewer details and less accuracy. Another instance where using low-resolution depth maps is preferable is when some kind of automation is employed for depth creation or editing, and the software takes too long to process full-HD content or produces artifacts, which are less visible in the case of lower resolution.

Thus, a company can save time by drawing depth maps for a downscaled video sequence and then increasing the depth map resolution to the initial size before the actual rendering of stereo from 2D-plus-Depth. Ordinary methods of increasing video resolution, however, are not always able to maintain sharp, correct boundaries in the upscaled depth maps, potentially causing visible artifacts in stereo.

YUVsoft offers a special tool for increasing the resolution of small depth maps: Depth Upscale. This plugin for Adobe After Effects is conceptually simple and is designed to work in combination with other YUVsoft depth estimation and processing plugins (for example, Depth Propagation).

Key features of YUVsoft Depth Upscale are

* Arbitrary upscale factors—the resulting depth map is upscaled to the resolution of the original 2D video
* Exact binding of boundaries in the upscaled depth map to boundaries in the original 2D frame
* Accurate processing of gradient areas to eliminate the staircase effect
