hey everyone and welcome back to this class the numpy stack in Python in this lecture we are going to look at how to plot images when you see an image file on your computer you might think its magic but in reality an image is still just a matrix of numbers each value in the matrix is the intensity of that pixel at that position in the image of course if you open a JPEG or a PNG file on your computer youre not going to see these numbers because these image formats make use of compression however when you decompress the image you get back a matrix of numbers the images well be looking at are from the famous eminence dataset these are small images of handwritten digits the format will also let us explore a few more numpy functions to get this data youll want to go to Cal comm /c / digit recognizer and click on the link that says data Im going to use trained dot CSV in this particular tutorial for most of the examples in my courses whenever we need a huge data file like this we wont
