Full color image processing
Color image mathematical representation
Let c represent an arbitrary color in the RGB color space,
the color components can be represented as a function of
spatial coordinates (x,y)

Full color image processing
Two major categories of full-color image processing
approaches
Per-color-component processing
Process each component image individually form a
composite processed color image
Vector-based processing
Work with color pixels (as a vector) directly
To make results of two approaches equivalent:
The image processing method has to be applicable to both
vectors and scalars
The operation on each component of a vector must be
independent of the other components
