Professional divers and their clients will recognize the image quality to the left as that of an ordinary underwater camera in fairly normal visibility. To the right you see what the LYYN visual enhancement technology can accomplish in real-time!

LYYN technology enhances video in real-time, decreasing visual disturbances and increases visibility. It addresses visibility problems caused by predominate water color,  turbidity, fog and low light. LYYN visual enhancement technology uses mathematical algorithms initially developed for medical diagnosis, the technology is packaged in easy-to-use products which will increase subsea productivity, real-time in live operations or in post processing video for analysis, documentation and report.

LYYN video enhancement is especially useful in detecting surface damage such as fatigue cracks, metal corrosion and concrete spalling.

Topside operations

LYYN technology comes as stand-alone products that connect directly into the divers video feed. Just plug LYYN into your topside monitor and the diving supervisor and client will have a better view in real-time.

The image from the diver’s helmet mounted camera is normally only displayed to the topside supervisor. All instructions therefore rely on the supervisor’s skill in directing the diver through an audible communications link. Under certain seawater conditions, where poor visibility exists, it is known that topside personnel have a better image of the diver’s immediate environment than the diver because of the performance of subsea cameras. This is especially true when the video is lyynified in real-time topside by the supervisor, using a LYYN or LYYN partner product.

Challenges of low light

Video cameras and strong illuminating lights on the helmets of commercial divers creates problems in turbid waters. Strong light reflections overexposes parts of the image rendering it useless. With a LYYN unit plugged in there are new ways to optimize the image. By reducing the light, or preferably remount the light source so that it does not point in the same direction that the video camera is, and instead turning up LYYN enhancement, the video image will become clearer with much greater detail.
