Subject: reddish image computed by Median Cut algorithm



I'm implementing Median Cut and Wu's Statistical color quantization
algorithms for my computer graphics course. Wu's works fine already (however
still there are some artifacts for quantization into a large number of
colors), but I'm still facing quite serious problems with the Median Cut.
The problem is that the quantized image is reddish. I mean the red
coordinate in every pixel seems to be really strong. I tried different
approaches for finding mid color for a box, but every time I got the same
result. Has anyone ever faced similiar problem? Any ideas what can cause
such weird behaviour?

regards
Marcin
