Message-ID: <BB742A9E-F98D-482D-8DA8-B3A2C5F71CD4@refined-audiometrics.com> (raw)
... as a specific example, I remember dealing with stacks of images
taken from an infrared imaging sensor -- perhaps 256 images, each of
which is, say 512 x 512 pixels. I needed to obtain median pixel values
from the stack and produce one "median image", as well as perform
thresholding, masking, perhaps some dilation and erosion. And, also
get the image 2-D FFT image.
So there we are dealing with an aggregate of 2^26 8-bit pixel values.
Surely, the majority of time is spent processing pixels, and not
dispatching over some polymorphic type...
