FASTSERIES OBJECT IMAGING LIBRARY(FOIL)
Alacron's FOIL is object-oriented so that
the format and type of objects are carried with the objects. When
library routines are called, the routine determines the fastest
way to perform the requested function between the objects. For example,
if a 512x512 image is operated on with a 3x3 floating-point kernel,
the calculation is performed in floating-point, returning a floating-point
result (to buffer memory). This feature significantly reduces the
variety of routines for the user to learn and reduces the chance
of an error.
Below is the current list of routines supported by the image processing
library. Most all of these functions can be performed by any of
the FastSeries products, before the image is returned to host memory.
Sequences of routines can be defined and executed automatically.
