Re: Measure or calculate blur amount (σ) of Gaussian blur algorithm
Standard deviation (SD) is a measure of blurriness of an image. It has a scale of 0.0 to 0.5, where 0.0 is a total blur (a constant colour) and 0.5 is as sharp as possible. Thank you, this helps a lot! I'm just wondering if ImageMagick (don't have access to it due to issues with my Linux, I'm on Wi...

Re: Measure or calculate blur amount (σ) of Gaussian blur algorithm
Thanks for your answer! How would you even find a sigma that is too small or too large? Can you provide more detail? You're right, now I also wonder why it is implemented in such an inefficient way that it will be iterated several times over the image. I do know which purpose the iterations have her...

Measure or calculate blur amount (σ) of Gaussian blur algorithm
Hi community, I'm generating blurred images with different blur amounts in Unity but I don't know how much blur (spoken in absolute values or in Sigma σ) is produced. Do you know any tool which allows measuring the blur amount of an image when the original image and the blurred version is provided? ...
