I am new to CUDA, I downloaded and compiled the CUDA sample source code SobelFilter, it worked well.
Now I tried to use a different input image (say, sample.ppm saved in C:\downloads), instead of the lena.pgm file in the /data folder.
In C:\NVIDIA Corporation\NVIDIA GPU Computing SDK\C\bin\win64\Debug, I found the SobelFilter.exe,
In a command prompt, I type “SobelFilter C:\downloads\sample.ppm”,
but I got an error:
“Error when parsiing command line argument string”,
Does anyone know what’s wrong with my commandline?
Thanks a lot!
