Min...
You should have an image already opened. A small window named Min is opened. Each pixel value lower than the chosen value (e.g. 300) is set to this value (e.g. 300). The values above are kept unchanged.
This function can be useful in special cases (e.g. if you have a bad saturated pixel which is negative). See also the other operation proposed in the menu Process/Single Image Operators.
It is not used in the actual series of EU-HOU exercises.
