into one image.
3.3.1 JAIBandSelect
The JAIBandSelect actor takes one array of integers as a parameter. The number
of bands at the output is equal to the length of the specified array. Each
integer in the array specifies the band to select at the input. This actor is particularly
useful in selecting a single band, or isolating image data from its alpha
channel.
3.3.2 JAIBandCombine
The JAIBandCombine actor takes a m by n + 1 matrix of floats as an input,
where m is the number of bands at the output, and n is the number of bands
at the input. The first n values of each row specify the scalar amount to multiply
each band by. The last value is a DC offset. In conjunction with the
Add/Subtract actor, this actor can be used to combine several images into one.
3.4 Filtering
Filtering allows us to deal with how the real world interferes with signals. Among
the many operations we can perform on signals (in this case images) are blur,
sharpen, and denoise.
