Specifying a brightness range to use for measurement eliminates the section outside that range as background.
In addition, the extracted range is converted into values of 0 to 255, so the contrast can be emphasized.
In addition, the extracted range is converted into values of 0 to 255, so the contrast can be emphasized.
Used in the Following Case
- By extracting a specific brightness range, the contrast on the image can be improved, unnecessary background eliminated, etc.
Basic concept of background suppression
Because input values from 0 to [Lower] are converted to level 0 and values from [Upper] to 255 are converted to level 255, the background in this range is eliminated.
Together with this, only [Lower] to [Upper] from the input values 0 to 255are taken and those are converted to output values of 0 to 255, so the contrast within this range is emphasized.
