I convert Image into CIELab color space. After that I split Image into 3 channels are Lightness,a,b . So I have 2 questions

  1. How can I decompose Lightness channel into Detail Layer.
  2. Assume I have a new Detail Layer. How can I combine with Lightness,a,b channels.

This is an example detail layer.

"detail layer" might need some explanation. opencv does not know it

Your image comes from here where we have the quote:

In log space, I filter the image with a bilateral filter and then subtract the filtered image from the log intensity image in order to retrieve the detail layer.

So like @Eduardo says, apply those functions, which are in OpenCV, and you will end up with this result!
