#Pil image convert l how to#
In this example, we have seen how to load an image, convert the Image into a numpy array, modify the numpy array, and then convert it back to image.
To enhance the performance of the predictive model, we have to know how to load and manipulate images.
In machine learning, Python uses the image data in the form of Numpy array, i.e., format. In this example, we have converted a PIL Image to Numpy array using the np array() method and then modify its pixel and converted the array to the PIL image using the fromarray() method. We can even modify the img_arr by subtracting the values and then create an image from the array using fromarray() function and save the image into the file system. If we want to change, modify or edit the Image using numpy, then first, we convert into numpy array and then perform the mathematical operation to edit the array and then convert back into the Image using Image.array() method. To convert a Numpy Array to PIL Image, we can use the omarray() method. Output (6000, 4000, 3) Convert Numpy Array to PIL Image The shape of the img_arr is the following. We have used the Image.open() method and np.array() method to convert PIL Image into Numpy array.
