Open Source Computer Vision Library (OpenCV) provides developers with over 2,500 optimized algorithms for a variety of computer vision use cases. From detecting/recognizing faces to classifying human actions, OpenCV makes understanding visual information a simple matter of calling the right function and specifying the right details. Paired with its robust community and extensive documentation, OpenCV is perfect for adding computer vision infrastructure to a project. Like the name suggests, computer vision allows machines to both see and understand what they’re seeing. Through videos and images, machines can figure out what objects they’re looking at and classify them into appropriate categories.

• It also provides an interface similar to MATLAB so a user can carry out similar tasks as MATLAB.
• Gensim aims to make the process of identifying the underlying topic of a piece of text (known as topic modeling) substantially easier.
• It uses APIs to hook into your code so it remains language independent.
• You can use the Python Pillow library to extract the cat from the first image and place it on the floor of the monastery courtyard.
• The output of the map function is a new dataset with each element now converted from the original image file to its corresponding pixel data.

Originally designed for mathematical and scientific computations, SciPy is also a top library for performing multi-dimensional image processing by importing the submodule scipy.ndimage. SciPy provides functions to operate on n-dimensional Numpy arrays. Another top image processing library on the market is Scikit-Image, which is used for nearly every computer vision task.

Mahotas is another image processing and computer vision library that was designed for bioimage informatics. It reads and writes images in NumPy array, and is implemented in C++ with a smooth python interface. Another open-source library for image processing tasks, Pillow is an advanced version of PIL (Python Imaging Library). With Pillow, you can carry out many processes in image processing like point operations, filtering, and manipulating. In this article, I tackled the first part of image recognition which is image processing. The quality of our Dataset has a lot of impact on the performance of our Neural Network algorithm.

Before we do any image processing, we need to understand how image files work. Specifically, we’ll discuss how these files use byte data and pixels to represent images. Closing out our list of 10 best Python libraries for machine learning and AI is Plotly, which is another free and open-source visualization library. It is highly popular among developers thanks to its high-quality, immersive, and publication-ready charts. Some of the charts that are accessible through Plotly include boxplots, heatmaps, and bubble charts.

The Keras library is often preferred due to it being modular, extensible, and flexible. It can also integrate with objectives, layers, optimizers, and activation functions. Keras operates in various environments and can run on CPUs and GPUs.

It provides functions to operate on n-dimensional Numpy arrays and at the end of the day images are just that. According to IDC, digital data will skyrocket up to 175 zettabytes, and the huge part of this data is images. Data scientists need to (pre) process these images before feeding them into any machine learning models. They have to do the important (and sometimes dirty) work before the fun part begins.

Images having shades of grey as their only color are grayscale images while a binary image has exactly two colors, mostly black and white pixels. Multispectral images are images that capture image data ranging across the electromagnetic spectrum within some specific wavelength. Keras is an open-source Python library aimed at the development and evaluation of neural networks within machine learning and deep learning models. It is capable of running on top of Theano and Tensorflow, which means it can train neural networks with little code. The image processing library is popular among those looking to easily create computer vision tasks. It enables users to get access to high-powered computer vision libraries like OpenCV without needing to learn about file formats, bit depths, color spaces, buffer management, and more.

Even though there are other Python libraries for image processing, Pillow remains an important tool for understanding and dealing with images. The Image module provides a class called Image that represents an image object. You can create an Image object from an existing image file or from scratch. The output of get_image_data is an array of size 1980x1710x3 as it is an RGB picture of pixels 1980×1710. But, for purposes of image processing, Numpy can help manipulate pixels, image cropping, and masking pixel values.

When we multiply the number of columns and number of rows, we can obtain the total number of pixels present in the image. For example, in a 320 x 240 image, the total number of pixels present in it is 76,800 pixels. I believe you have already installed Python Shell/Jupyter Notebook/PyCharm or Visual Studio Code (to name a few) to program in python.

TensorFlow consists of an architecture and framework that are flexible, enabling it to run on various computational platforms like CPU and GPU. With that said, it performs best when operated on a tensor processing unit (TPU).
