Unless image resizing or datatype conversion must be performed the image data can be shared by the NIfTI image and accessing NumPy arrays, and therefore memory won’t be wasted memory with redundant copies of the image data. However, one should be careful to make a copy of the image data if you intend to resize and cast the image

Image(anchorPoint, filename) Constructs an image from contents of the given le, centered at the given anchor point. Can also be called with width and height parameters instead of filename. In this case, a blank (transparent) image is created of the given width and height (in pixels). Example: flowerImage = Image(Point(100,100), "flower.gif")

basic image is just a standard NumPy array, which exposes pixel data directly to the user. A new user can simply load an image from disk (or use one of scikit-image’s sample images), process that image with one or more image filters, and quickly display the results: fromskimageimport data, io,filter image=data.coins() # or any NumPy array!
