A simple Canny edge detector demo using SimpleCV.

edges.py

# Make a function that does a half and half image.
def halfsies(left,right): 
    result = left
    # crop the right image to be just the right side.
    crop   = right.crop(right.width/2.0,0,right.width/2.0,right.height)
    # now paste the crop on the left image.
    result = result.blit(crop,(left.width/2,0))
    # return the results.
    return result
# Load an image from imgur.
img = Image('http://i.imgur.com/lfAeZ4n.png')
# create an edge image using the Canny edge detector
# set the first threshold to 160
output = img.edges(t1=160)
# generate the side by side image.
result = halfsies(img,output)
# show the results.
result.show()
# save the output images. 
result.save('juniperedges.png')

ran a complete clean install on a new pc and the Python shell says it doesn't recognize simplecv. Any ideas anyone? Thanks!!

not simplecv but SimpleCV
code shall be
from SimpleCV import Image
Try this

Thank you for the help funshockindia! Now I'm getting:
