Opencl filtering
Web23 de out. de 2024 · I recently use tonemap_opencl filter in ffmpeg to do H2S conversion on the fly. Therefore, it is necessary to use hwupload to copy data from host to device, but this process has become a bottleneck for APU.. I know that AMD APP already supports interop between DXVA2 and OpenCL, but this extension only supports NV12, and many … WebWhile most filtering approaches based on random finite sets have focused on improving performance, in this paper, we argue that computation times are very important in order to enable real-time applications such as pedestrian detection. Towards this goal, this paper investigates the use of OpenCL to accelerate the computation of random finite set-based …

Also nlmeans_opencl is an opencl accelerated equivalent. I used the nlmeans_opencl filter with a new NVidia GPU and got 10fps with default settings, and 18fps with p=5:r=11 which led to great results on 1080p captures of grainy film. – polpetti.

Web20 de jan. de 2015 · OpenCL provides min-max-functions which operate component-wise. This scheme should be adapted to fit your grid data (sorry for the remaining work). – Christian Jan 21, 2015 at 11:08 Better solution of course is: float nearest = clamp (x,1, n-1) (see above answer) – Christian Jan 21, 2015 at 11:15 Add a comment Your Answer Post … WebThis filter is designed for applying long FIR filters, up to 60 seconds long. It can be used as component for digital crossover filters, room equalization, cross talk cancellation, wavefield synthesis, auralization, ambiophonics, ambisonics and spatialization. This filter uses the streams higher than first one as FIR coefficients.
