Volume of an Ellipsoid Enter the labels "Radius 1," "Radius 2" and "Radius 3" in cells A1, B1 and C1, respectively. Enter the following formula in cell D2: \=(4/3)_PI()_A2_B2_C2 Enter the three different radii for the ellipsoid whose volume you want to enter in cells A2, B2...
These simple changes will reduce execution time to half. Is that enough? Maybe not. Further lines of improvement: the img_to_array() operation is being applied many times on every image (every time you calculate similarity with another one). Is it a bottleneck? In that case, perfo...
