Noise is a signal that can cause certain disturbances. It is often associated with sound but can also be associated with an image.
Noise images can be helpful. For instance, you may use noise images to generate CAPTCHA validation images that may obfuscate a picture with text that the user needs to recognize.
The noise image can help obfuscate the text to make it harder for robots to recognize the text while humans may be able to identify it.
This package can generate noise data for creating noise images for CAPTCHA validation or other purposes.
It uses the SimpleX noise algorithm. This algorithm has several advantages over classic forms of generating noise like the Perlin algorithm.
For instance, the simplex algorithm requires less computing power to create noise.
