30th August, 2023

Image processing is a very useful technology and the demand from the industry seems to be growing every year. Historically, image processing that uses machine learning appeared in the 1960s as an attempt to simulate the human vision system and automate the image analysis process. As the technology developed and improved, solutions for specific tasks began to appear.

The rapid acceleration of computer vision in 2010, thanks to deep learning and the emergence of open source projects and large image databases only increased the need for image processing tools.       

Currently, many useful libraries and projects have been created that can help you solve image processing problems with machine learning or simply improve the processing pipelines in the computer vision projects where you use ML.

In this article, we give you a list of tools that will improve your computer vision projects divided into:

  • frameworks and libraries
  • datasets 
  • ready-made solutions for particular tasks

Let’s dive in!

Frameworks and libraries

In theory, you could build your image processing application from scratch, just you and your computer. But in reality, it’s way better to stand on the shoulders of giants and use what other people have built and extend or adjust it where needed.

This is where libraries and frameworks come in and in image processing, where creating efficient implementations is often a difficult task this is even more true.

You cannot build machine learning models without the data. This is especially important in image processing applications where adding more labeled data to your training dataset usually gets you bigger improvements than state-of-the-art network architectures or training methods.

With that in mind, let me give you a list of image datasets that you can use in your projects: 

Diversity in Faces

A dataset designed to reduce the bias of algorithms.

A million labeled images of faces of people of different nationalities, ages and genders, as well as other indicators – head size, face contrast, nose length, forehead height, face proportions, etc. and their relationships to each other.


Dataset for recognizing fake photos and videos.

A set of images (over half a million) created using the Face2Face, FaceSwap and DeepFakes methods.

1000 videos with faces made using each of the falsification methods.

Approximately 237 thousand layouts and 1000 categories.


Dataset for training neural networks to generalize

The data consists of real-world tagged images and unlabeled sketches.


Dataset for counting objects in drone images.

15,532 RGB drone shots, there is an infrared shot for each image.

Object marking is available for both RGB and infrared images.

The dataset contains directional object boundaries and object classes.

In total, 441,642 objects were marked in the dataset for 31,064 images.

Waymo Open Dataset

Dataset for training autopilot vehicles.

Includes videos of driving with marked objects.

3,000 driving videos totaling 16.7 hours, 600,000 frames, about 25 million 3D object boundaries and 22 million 2D object boundaries.

To eliminate the problem of uniformity of videos, the recordings were made under various conditions. Video options include weather, pedestrians, lighting, cyclists, and construction sites.

Diversity in the data increases the generalization ability of the models that are trained on it.

Based on the test results, the models predicted objects from the dataset with an accuracy of 3%.
