This plugin allow conversion between RGB color space (8 bits per pixel chanel) and Lab color space (32 bits [float] per pixel channel )

It convert a RGB image to a new image-stack containing 3 slices L,a,b.

In the ImageJ menu, choose “Plugin / Image / Color / Convert RGB image to Lab color stack v1.00”

Convert a Lab stack image to a new RGB image.
