Hi everybody, first of all I wish you a happy new year :) I have a problem with the Shape Index <http://scikit-image.org/docs/dev/auto_examples/features_detection/plot_shape_index.html#sphx-glr-auto-examples-features-detection-plot-shape-index-py>example. When I try with my image (shape (778, 1802, 3)) I am getting the following error message: Traceback (most recent call last): File "C:/Users/stefanie/PycharmProjects/BluVision/Testing/shape_index.py", line 16, in <module> s = shape_index(image) File "D:\Anaconda\lib\site-packages\skimage\feature\corner.py", line 419, in shape_index l1, l2 = hessian_matrix_eigvals(H) ValueError: too many values to unpack (expected 2) System: scikit-image 0.14.1 Windows 10 Python 3.6 Any suggestions? Thanks Stefanie
