Question

I want to display images using different color maps in different figures.

Following code displays the image with two different windows but the same color map

   import scipy.misc
   from pylab import *

   a = scipy.misc.imread('lena.jpg')
   figure(1)
   image = mean(a,axis=2)
   imshow(image)
   #if I call show() here then only one window is displayed
   gray() #change the default colormap to gray
   figure(2)
   imshow(image)
   show()

I am wondering if anyone can please help me.

Thanks a lot.

You can pass the cmap argument to the imshow function. Look at http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
