Cel-Scope3D gets edge detection

Cel-Soft has added an automatic detection of edge-violation to its stereoscopic signal analyser, Cel-Scope3D. Edge-violation can be fixed in post production, but is best handled if alerted to the problem during the initial shoot. “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,” explains Cel-Soft Founder, 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.” Palmer adds: “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 1.4, edge-violation can be displayed automatically. 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 3D signal monitoring software can analyse file-based content as well as live or recorded signals in dual-stream or multiplexed formats. 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.
