PIL, SciPy, and OpenCV • Use im.as to get PIL, Scipy, and OpenCV images. • Perform operations using preferred library. • Convert back using pv.Image() • Note: Scipy format matrices are transposed so that mat[x,y] correspond to the x and y image axis. 39

PIL is a “Python Imaging Library” used for image manipulation. PIL/Pillow offers several standard procedures for image ... To perform further tasks we convert the image into b&w image i.e. a two-dimensional signals. To convert the image into b&w ... because Numpy calculates bins as 0-0.99, 1-1.99, 2-2.99 etc. So final range would be 255-255 ...

PIL consists of several classes with di erent image related functionalities and the standard way to use PIL in your own code is by importing those classes using the \From PIL import xx" syntax. To make it clearer, my Python module for the ICP algorithm starts with the following declarations: from PIL import Image from PIL import ImageFilter

How to Convert PIL Image to Numpy Array in Python
Between PIL and NumPy •np.array(im)—create NumPy array from image data •Very commonly used for doing machine learning on images •We did just that in HW 5! •Image.fromarray(im)—create image from array •As we saw in HW 5, we need the array to be of type unit8

Convert PIL image into NumPy array and obtain the image ID from trained images. 6. Append each face to its respective ID and add image to face sample. 7. Load the trained model and the pre-built model and then create a classifier from the pre-built model. 8. Set a font style, initialize and start capturing the
