VIPER Lab Server Status

The Video and Image Processing Laboratory (VIPER), directed by Professor Edward J. Delp, is equipped with state-of-the-art technology to digitize, store, process, stream, and display digital images and video. VIPER supports research in areas such as the development of new image analysis techniques, new image and video compression methods, the development of new surveillance and detection methods, new media and wireless streaming technologies, and creating multimedia material for use in media indexing, storage, and retrieval.

Depending on the application, digitizers in the laboratory can produce digital video in a variety of formats including uncompressed CCIR video, motion JPEG, DV, MPEG-1, MPEG-2, MPEG-4, H.26X, and HDTV. Several high quality image scanners are available to support digital image acquisition at various resolutions. VIPER also has hundreds of digital cameras and more than 60 mobile telephones.

The storage facilities of the Laboratory are organized around 7 high performance servers. The servers are connected to the Purdue Engineering Computer Network (ECN) and INTERNET2. They have a total disk storage capability of more than 20 terabytes. VIPER also has an extensive database of image and video consisting of more than 800,000 digital images acquired from various cameras and sensors and more than 1000 hours of digital video including both standard definition and high definition video.

Finally, the Laboratory has a variety of methods used to display digital images and video. All display devices are connected to a video cross-bar switch so that a wide variety of possible input and output scenarios may be configured at the touch of a button. For primary viewing, the laboratory has two 50" color calibrated monitors and two 40" color calibrated monitors so that A/B comparisons may be made directly.
