DRASTIC



DRASTIC is focused on the development of adaptive video processing systems that can change in response to content, their environment, or user needs. The DRASTIC platform allows changes in both the software and the hardware that is used to process the videos.

DRASTIC architectures for digital image and video processing

By adapting to video content, user demands, or external constraints, DRASTIC can provide significant savings in 2-D filtering applications. Furthermore, as demonstrated in the Discrete Periodic Radon Transform (DPRT) paper, DRASTIC requires both fast and scalable implementations.
