Python allows image processing using different libraries and one of them is Pillow, which is an open-source Python Imaging Library that adds image processing capabilities to your Python interpreter. Pillow offers all types of capabilities like image transformation, rotation, resizing, statistics of the image, etc.

How do you use a pillow image in Python?

To load the image, we simply import the image module from the pillow and call the Image. open(), passing the image filename. Instead of calling the Pillow module, we will call the PIL module as to make it backward compatible with an older module called Python Imaging Library (PIL).

What is Pillow python used for?

Pillow is a Python Imaging Library (PIL), which adds support for opening, manipulating, and saving images. The current version identifies and reads a large number of formats. Write support is intentionally restricted to the most commonly used interchange and presentation formats.

2. Parameters: box – a 4-tuple defining the left, upper, right, and lower pixel coordinate.
3. Return type: Image (Returns a rectangular region as (left, upper, right, lower)-tuple).
4. Return: An Image object.

How do you process an image in Python?

Let's get started

1. Step 1: Import the required library. Skimage package enables us to do image processing using Python. ...
2. Step 2 : Import the image. Once we have all the libraries in place, we need to import our image file to python. ...

It's the same library, it just has a different name between Python 2 and 3. As you're using 3.6, use Pillow. ... The original library is PIL, which was for Python 2. Pillow is a fork of PIL and is the current, actively maintained project, which is also compatible with Python 3.

What is cv2 Python?

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2. imread() method loads an image from the specified file. If the image cannot be read (because of missing file, improper permissions, unsupported or invalid format) then this method returns an empty matrix.

How do I crop an image in Numpy?

Explanation:

1. Firstly we imported the Image module of the PIL (or pillow) library. ...
2. To create Numpy array out of this object, we passed it through the np. ...
3. Then we sliced the array from each dimension. ...
4. Finally, we converted the Numpy array back to an image using Image.
