7 Best Computer Vision Development Libraries in 2024
From the widespread adoption of OpenCV with its extensive algorithmic support to TensorFlow's role in machine learning-driven applications, these libraries play a vital role in real-world applications such as object detection, facial recognition, and image segmentation.
10 Python Libraries for Computer Vision
OpenCV is the go-to library for computer vision tasks. It boasts a vast collection of algorithms and functions that facilitate tasks such as image and video processing, feature extraction, object detection, and more. Its simple interface, extensive documentation, and compatibility with various platforms make it a preferred choice for both beginners and experts in the field.

Top 8 Alternatives to OpenCV for Computer Vision and Image Processing
OpenCV is an open-source computer vision and machine learning software library that was first released in 2000. It was initially developed by Intel, and now it is maintained by the OpenCV Foundation. OpenCV provides a set of tools and software development kits (SDKs) that help developers create computer vision applications. It is written in C++, but it supports several...

Top 8 Image-Processing Python Libraries Used in Machine Learning
These are some of the most basic operations that can be performed with the OpenCV on an image. Apart from this, OpenCV can perform operations such as Image Segmentation, Face Detection, Object Detection, 3-D reconstruction, feature extraction as well.

5 Ultimate Python Libraries for Image Processing
Pillow is an image processing library for Python derived from the PIL or the Python Imaging Library. Although it is not as powerful and fast as openCV it can be used for simple image manipulation works like cropping, resizing, rotating and greyscaling the image. Another benefit is that it can be used without NumPy and Matplotlib.

Which Python GUI library should you use? Comparing the Python GUI libraries available in 2023
Before the Qt Company (under Nokia) released the officially supported PySide library in 2009, Riverbank Computing had released PyQt in 1998. The main difference between these two libraries is in licensing. The free-to-use version of PyQt is licensed under GNU General Public License (GPL) v3 but PySide is licensed under GNU Lesser General Public License (LGPL). This means...
10 Best Python Libraries for GUI
Developed by Riverbank Computing, PyQt5 is one of the most popular Python frameworks for GUI. The PyQt package is built around the Qt framework, which is a cross-platform framework used for creating various applications on different platforms.

Top 10 Python GUI Frameworks for Developers
When it comes to creating GUIs, the PyQt5 arsenal offers the impressive QtGui and the QtDesigner module, which provide numerous visual elements that the developer can implement with a simple drag and drop. Of course, the option of creating these elements by code also exists, allowing you to create both small-scale as well as large-scale applications with ease. Python’s...

    Open the camera feed — and use the OpenCV library for real-time computer vision processing. - Source: dev.to / 2 days ago
  • Exploring Open-Source Alternatives to Landing AI for Robust MLOps
    Data analysis involves scrutinizing datasets for class imbalances or protected features and understanding their correlations and representations. A classical tool like pandas would be my obvious choice for most of the analysis, and I would use OpenCV or Scikit-Image for image-related tasks. - Source: dev.to / 5 months ago
  • Looking for a Windows auto-clicker with conditions
    You might be able to achieve this with scripting tools like AutoHotkey or Python with libraries for GUI automation and image recognition (e.g., PyAutoGUI https://pyautogui.readthedocs.io/en/latest/, OpenCV https://opencv.org/). Source: 6 months ago

  • Python vs. JavaScript: Is It a Fair Comparison?
    JavaScript is a clear winner in the category of mobile development. There are some niche frameworks to do mobile development with Python—like Kivy and PyQT—but pretty much nobody uses them. - Source: dev.to / about 2 years ago
  • what would be the best looking GUI framework to develop a desktop python application? (other than Tkinter)
    If none of those are to your liking, you can use PyQT (or Pyside) but the learning curve is much steeper. Source: about 2 years ago
  • Is there a "Windows Forms" GUI designer for Python?
    Also, there is the PyQt module which is a comprehensive set of Python bindings for the Qt GUI. It has Qt Designer. Source: almost 3 years ago
  • Best way to install qutebrowser?
    As for PyQt, that's developed entirely independently from Qt (by Riverbank Computing). The major/minor versions usually line up with the respective Qt releases (since the Qt release introduces new APIs, so a new PyQt release is needed to expose those to Python). However, it's versioned independently, and a new patch release of PyQt might be needed before/without Qt releasing a new patch release. For more details,... Source: about 3 years ago
