Contrast for IdentifyObjectsManually


#1

I’m need to crank up the image contrast so I can identify my objects. Log normalization (via right-click) is not enough. What is a good method for adjusting the image prior to the IOM module?

Thanks!

Hi,

You probably want the RescaleIntensity module.

Right, well I had hoped that would do it, but I’m having trouble finding
the correct parameters. Even if I try the Log2(image+1) function, I still
get back (in appearance when CP displays it) a similar image.

Hi,

You can also try to use ImageMath, where you first log transform it, then multiply the resulting image by a large number, like x8, x16, x32.
