Histogram

Post by Forum_2014 »

Hello,

When should I stop stretching the histogram?
What looks like a perfect histogram? What aspect?

Why there are two kinds of histograms in a "visualization" and in a "filter"?

Thank you for your help
Virginie

Hello,

The visualization histogram does not modify the image, so you can stretch it forever. You usually stop when you publish your image in jpg on your website / personal page.
The filter histogram is usually used a step of a filter procedure. After that histogram your original data is lost forever.
