Viso Suite is the all-in-one solution for teams to build, deliver, scale computer vision applications. Computer vision is a branch of artificial intelligence that deals with providing computers with the ability to see and interpret the world in the same way that humans do. This involves understanding both the visual data that is captured by sensors such as cameras, and the high-level concepts that allow humans to make sense of this data.


Faster than all other object detection tools out there, YOLO owes its speed to the application of a neural network to the complete image, which then partitions the image into grids. The software then simultaneously predicts the probabilities of each grid. Yolov5 is a pre-trained model for object detection available as a Python library. It is one of the most powerful models for object detection that you can use in any computer vision task where you want to detect the object in an image. Just like Tensorflow and PyTorch, it can also be used with OpenCV to detect objects in real-time using a camera. Python is a mainstay when it comes to computer vision or artificial intelligence in general.

Pytesseract – Python-tesseract is an optical character recognition tool for python. That is, it will recognize and “read” the text embedded in images. Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine. It is also useful as a stand-alone invocation script to tesseract, as it can read all image types supported by the Pillow and Leptonica imaging libraries, including jpeg, png, gif, bmp, tiff, and others. Additionally, if used as a script, Python-tesseract will print the recognized text instead of writing it to a file.

It supports various programming languages, including C, C++, Python, Fortran, or MATLAB, and is also compatible with most operating systems. You can analyze an image for certain features with analyze_image. Use the visual_features property to set the types of analysis to perform on the image.

Best Python Libraries for Computer Vision

This could work to improve photo and video quality, as in our example at the beginning of the article, or it could also serve more advanced use cases. Facebook famously uses facial recognition to let you review pictures in which your friends might have forgotten to tag you. Likewise, Apple’s Face ID feature tracks facial features to let you seamlessly unlock your iPhone.

It also provides researchers with low-level components that can be mixed and matched to build new approaches. SimpleCV is an open source framework for building computer vision applications. You Only Look Once, or YOLOv7 is among the fastest computer vision tools you can opt for in 2023.
