seam-carving's Issues

Inverted colors when using plt.imshow()

When using the new added function plotResult(), the plt.imshow() call for the original image and the output are displayed with inverted colors. I've tried to plot them using the .astype(np.uint8) attribute, but without success.

'AttributeError' when trying to use Canny edge detector for energy mapping

I'm trying to implement the Canny edge detector in the BackwardEnergy class for energy mapping by adapting the code from https://github.com/FienSoP/canny_edge_detector.

I've made some adjustments to call the edge detector by using the 'be.canny(img)' statement in the main program sc.py but I'm getting an 'AttributeError' when trying to run the program:

foo@bar ~ % python3 sc.py -in image.jpg -scale 0.5 -seam h -energy c
