Ichika (2004-11-30)
Red eye filter.
Usage:
ichika input.bmp output.bmp
ichika input.ppm output.ppm
Input must be either truecolor uncompressed Windows BMPs, or truecolor
raw PPMs. Output will be in the same format as input. BMP support
only works on little-endian machines.
Unlike other red eye filters, Ichika *adds* red eye to an image. That
is, Ichika finds blue eyes in a bitmap and change the color hue to
red.
Doesn't work for every image though. In fact, only works for images
with Ichika in it, under certain lightning conditions. Images under
the samples/ directory are guaranteed to work. I encourage people to
capture more images from Uta Kata to try it out ^_^
It takes only one byte change to make Ichika a green eye filter (edit
line 33). It's more difficult to calibrate the settings for someone
else's eye/face. Those are left as exercises to the reader.
