Holoscan Framework/Holoscan Sensor Bridge/Performance: Difference between revisions

We have optimised our application by integrating CUDA ISP into the Holoscan Sensor Bridge. CUDA ISP integrates an outstanding algorithm for colour correction and auto-white balancing with RGB space. It adjusts the histograms of each colour channel within a confidence interval, leading to a more complete colour balancing. Recalling the baseline pipeline, our optimization implies dropping the ISP Processor block and replacing the Gamma Correction block with the CUDA ISP block, leading to the following pipeline:

Each of these blocks is executed in parallel for pipeline-like acceleration. Removing one of the blocks will shorten the frame processing time (latency), and further optimizing any of these blocks will also decrease the latency. In this case, the CUDA ISP manages to reduce one block.
