Detailed Description

template<class T>
struct vil_rgb< T >

This is the appropriate pixel type for 24-bit colour images.

Currently also includes the following ‘utilities’:

• conversion to ubyte (luminance of vil_rgb: weights (0.299,0.587,0.114)).
• min and max of vil_rgbcell values, useful for morphological operations.
• arithmetic operations
