The GStreamer element is called "rrnoisereduction". This element performs the noise reduction stage, described in the Overview section. This element receives as input a bit mask in GRAY8 format and outputs a GRAY8 bitmask.
Main Properties
- Size: The size of the gaussian filter. By default it is “3”, which is the default size of the kernel. Must be an odd number and also an integer.
- Threshold: The threshold limit for the image binarization. By default it is “128”,so the algorithm only takes into account the pixels between 128 and 255. Must be an integer.
