Hello, everyone,

I'm trying to seperate some images by their content.
The problem is that I use "ij.process.ImageProcessor.convertToFloat".

I doute this operation lose a lot of information.
Because after that the imageJ cannot seperate clearly the color image
and grey-level image.
However, the SIFT operator seems to be based on it, and nothing can be
changed.

So my question is :
- Did anybody know what happens during the "convertToFloat" operation?
Did color information (usually 3 matrix) lose?
- If so, how to catch the lost information?

cheers, Xin
