Cel-Soft Takes Cel-Scope3D 'To The Edge'

Cel-Soft has announced a major new addition to the feature set of its Cel-Scope3D stereoscopic signal analyser: automatic detection of edge-violation.
"Edge-violation is a visual artefact that can arise when part of an object is visible at the edge of one image pair but not at the other," explained Cel-Soft founder and Managing Director Robin Palmer.
"The brain normally compensates for edge-violation when viewing the real world, as it does with many other inherent defects of human visual perception. Viewing through a television or cinema frame, however, it can become confused."
"Edge-violation can be fixed in post-production but is best handled if you are alerted to the problem during the initial shoot," Robin Palmer added.
"Spotting where edge-violations are occurring takes a practiced eye as they may not be as obvious as the lamp post. The search window has to be very wide as edge-violation objects are likely to be close to the cameras and therefore to have large horizontal disparities. If these match in any position, they are not edge-violators."
Using the latest version of Cel-Scope3D, edge-violation can be displayed automatically in several ways. Alarm messages can be superimposed on the analyser's display screen as soon as the violations are detected.
Additionally, the offending objects are visually yellow-highlighted on the depth map display. With the logging option, edge-violations can be automatically logged timecode in a report along with over 30 user settable parameters and checks.
The automatic edge-violation detection feature is additional to the depth spectrogram, which was introduced at IBC2011 in September. The depth spectrogram allows the full depth dynamics to be viewed and make spotting 2D to 3D converted material very easy by its signature.
A highly cost-effective solution to the task of 3D signal monitoring, Cel-Scope3D 1.4 can analyse file-based content as well as live or recorded signals in dual-stream or multiplexed formats. It allows stereoscopic camera alignment to be performed quickly and confidently, ensuring 3D is accurate from the moment of capture. Footage and edits in a wide range of file formats can be viewed and assessed in real time. Disparities are analysed and displayed as clear and intelligible graphics on 2D or 3D monitors. Anaglyph display, user presets and on-screen-alarms are all provided.
Cel-Scope3D generates live displays which can be scaled and arranged as six or eight windows on one or two PC monitors. Left and right channels can be viewed simultaneously together with actual depth dynamics.
Each graphic window can be set to show waveform, vectorscope and histogram graphics as well as differences in video parameters between each channel. Geometry issues can be identified easily using built-in real-time image manipulation. Quality-control tests can be performed on live stereoscopic video sources in any 720p, 1080 or 2K formats from industry standard capture cards and input devices or from file playback.
Cel-Soft's products can be supplied as ready-to-load software-only or as complete turnkey systems running on workstation-class PCs or laptops for field use.
