computer vision libraries

We, humans, can quickly identify objects due to our biological sensors: eyes. However, computers don't "see" things the way we do. It takes a lot of data and hardware (cameras, sensors) for a computer to recognize a single object. Just like human eyes help us see and react to the world around us, computer vision enables a machine to identify, classify, and respond to the objects it sees.

Today, it's no secret that computer vision has multiple applications across many industries including security, agriculture, medicine, and more. So the demand for quality computer vision tools and libraries increases accordingly. There are various vision libraries, image recognition libraries, and face recognition libraries, that's why we've decided to compose this list of powerful computer vision libraries for you to easily filter and find the ones that fit your needs best.

What is a computer vision library?

A computer vision library is basically a set of pre-written code and data that is used to build or optimize a computer program. The computer vision libraries are numerous and tailored to specific needs or programming languages.

Popular computer vision libraries

In addition to the top 15 computer vision books, we've gathered a list of the most popular computer vision libraries in this article to help you get started. Without further ado, let's dive in.

  • OpenCV
  • Scikit-Image
  • Pillow (PIL Fork)
  • TorchVision
  • MMCV
  • TensorFlow
  • Keras
  • NVIDIA Performance Primitives
  • OpenVINO

1. OpenCV

OpenCV is the oldest and by far the most popular open-source computer vision library, which aims at real-time vision. It's a cross-platform library supporting Windows, Linux, Android, and macOS and can be used in different languages, such as Python, Java, C++, etc. OpenCV has a Python Wrapper and uses the CUDA model for GPU. Originally developed by Intel, it is now free to use under the open-source BSD license. It also contains some models that can be converted into TensorFlow models. A few use cases of OpenCV include:

  • 2D and 3D feature toolkits
  • Facial recognition application
  • Gesture recognition
  • Motion understanding
  • Human-computer interaction

scikit image

2. Scikit-Image

Scikit-Image is considered to be the most convenient and natural Python library which is an “extension” of Scikit-Learn. It is one of the most commonly used tools for supervised and unsupervised machine learning. Scikit-Learn is a Python package that is used for image processing and operating natively NumPy arrays as image objects. As it is Naturally Python and uses the Scikit-cuda module, Scikit-Image is free of charge and restrictions. To properly use Scikit-Learn, you just need to pip install it and you're good to go. Its use cases are a variety of:

  • Finding exoplanets
  • Data classification, identification, and recognition
  • Clustering similar data into datasets
  • Detecting fraud in credit card transactions
  • Interoperability with other libraries

3. Pillow (PIL Fork)

Next on our computer vision library list is Pillow, the friendly PIL fork by Jeffrey A. Clark (Alex) and contributors, an open-source library for the Python programming language. It can be utilized by Windows, Mac OS X, and Linux. The Python Imaging Library provides image processing capabilities to the Python interpreter and its image library is modified for fast data access. It can be used in both C and Python languages and it has a Python Wrapper. Mostly used for reading and saving images of different formats, Pillow also comprises different basic image transformations such as rotation, merging, scaling, etc. Once again, for its usage, you just need to pip install it. The use cases of Pillow are:

  • Fast access to stored data
  • Saving various image file formats.
  • Extensive file format support
  • Internal representation
  • Image processing capabilities.

4. TorchVision

As an extension of a PyTorch library, TorchVision contains the most common image transformations for computer vision. It also contains datasets and model architectures for computer vision neural networks. One of the main goals of TorchVision is to provide a natural way of using computer vision image transformations with PyTorch models without converting them into a NumPy array and back. Its package comprises common datasets, model architectures, and regular computer vision image transformations. TorchVision is Naturally Python and it can be used for Python and C++ languages. You can use it with the PyTorch library by pip install.



MMCV is a type of PyTorch extension that provides image/video processing and transformations, image and annotation visualization, and also many CNN architectures. It supports systems such as Linux, Windows, and macOS, and it is one of the most beneficial toolkits for computer vision researchers. It is used for Python, C++, and CUDA and it has a Python Wrapper. You can either pip or mim install it and use it in your jupyter notebook. Some of MMCV's use cases are:

  • Universal IO APIs
  • Useful utilities (a timer, progress bar, etc)
  • PyTorch runner with a hooking mechanism

6. TensorFlow

Created by the GoogleBrain team, TensorFlow was released in November 2015 and aimed at facilitating the process of building AI models. It has customized solutions such as TensorFlow.js, a JavaScript library for training and deploying models in the browser and on Node.js, or TensorFlow Lite, a lightweight library for deploying models on mobile and embedded devices. TensorFlow has now come up with a better framework, TensorFlow Hub. It's an easy-to-use platform where you can do the following:
