===== Conversions between RGB color space and Lab color space =====

====Description====

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


====Converting RGB to Lab====

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"

====Converting Lab to RGB====

Convert a Lab stack image to a new RGB image.

In the ImageJ plugin, choose "Plugin / Image / Color / Convert Lab stack to RGB image v1.00"

====Lab space====

From luminance 0 -> black to luminance 100 -> white
