I'm working with large tiff images (~~16k x 16k). I used slicing image for 9 tiles in my algorithm (library: image_slicer) before image processing.
I'm looking for some faster alternative method of slicing image for tiles. This one is so slow - when i open 4-5 images in once time, algorith slicing images for few minutes.
I tried to use img=img[x:y , x:y], but this method crashed my python application.
