Working on video files

I have a hardware that generates .yuv or .bin video files.

 

What functions are available to extract data such as SNR?

 

Do I need an addon toolkit for this work?

 

Thanks,

Masoud

Hello Masoud,

 

What is your definition of SNR?

 

If the noise includes distortion, you can use Sine in Noise and Distortion VI would do exactly that. If you want the ratio between signal and true noise, then you can use Harmonic Distortion VI to extract the signals to compute SNR.

 

All the associated VIs are located in Programming>>Waveform>>Analog Waveform>>Waveform Measurement provided that you have Full Development System or higher. Here's another thread that has great information on SNR and associated examples.
