Video Processing
Digitized video images in YUV format may be transferred from the
capture buffer to host memory by the Topaz/Stratus/Garnet acting as a
DMA PCI bus master. Once in host memory, the video data may be
archived for retrieval and display at a later time. Alternatively, the host
CPU can perform a color space transform on the YUV data or extract the
luminance in order to generate an 8-bit gray-scale image. Image
enhancement algorithms may be applied in surveillance or monitoring
applications, or edge-detection algorithms in automated (robotic) process
control applications.
