Somewhere... But where is it?
NumPy, SciPy, Matplotlib, Cython or ipython?
I am suspecting ipython, but proving it is hard...
http://nbviewer.ipython.org/urls/dl.dropboxusercontent.com/u/12464039/lenna-... When plt.imshow() is given floating point RGB images, it assumes that each channel is normalized to 1. You are mixing a 0..255 image with a 0..1 image. Divide `lenna` by 255.0 before you stack it with `_dct`. Or multiply `_dct` by 255 and cast it to uint8. -- Robert Kern
