How the L C H Values Could Be Seen as a value on an Image

Hi All,

I am trying to check an image file to reach its color values and I could see RGB but while trying to check the commands for Lightness Chroma and Hue values I got the same error all the time. It is usually varargin error.

Is there anybody knows how to pass this error?

I am using:

   disp(sprintf('RGB2LCH: unknown option %s',varargin{k}))

The document I referred to indicates that firstly convert it to L*a*b. I have already tried it but had the same error.

I don't know what function you're using or what you're passing into it, so I can't answer your question without more info. In general you can convert RGB into some other color space and get the values of those other color space channels by specifying the row and column just like you do with the red, green, or blue channels.
