 The image processing research and development laboratory explores the use of image processing to push the boundaries of surveillance and autonomous systems. The main streams of research include development of algorithms, architecture and platforms for hard real-time image processing systems.
The Huriccane image processing card is an embedded system capable of running multiple algorithms simultaneously while being lean on power usage. It has been designed to be free from the shackles of legacy video formats. This is accomplished by providing two digital video inputs based on the industry standard Cameralink specification. Legacy video signals can still be utilized by using the accompanying converter module that digitises the analogue video, then formats and streams the video over the Cameralink cable, to the image-processing card. Internally a field programmable gate array (FPGA) uses a generic pipelined architecture, which enables the image-processing card to make full use of the available processing time. This architecture has the benefit of simplifying the specification and development of algorithms. The system currently uses 10-bit processing. Some of the algorithms are:
- Contrast Enhancement
- Zoom
- Gaussian Noise Reduction
- Motion Detection
- Information Overlays
- False Colour Mapping
- Speckle Noise Reduction
- Edge Enhancement
