reCAPTCHA Reviews

Cloudflare replaced reCAPTCHA with hCaptcha. I followed their example. It took me 18 min.
Cloudflare announced yesterday that they are moving away from Google's reCAPTCHA in favour of hCaptcha. In my opinion, that is huge! Given the amount of traffic transiting through CloudFlare. That has cut some significant level of vision from Google's all-seeing and tracking eye. Moreover, they are giving a good example for others to follow.

Moving from reCAPTCHA to hCaptcha
Since Cloudflare's earliest days, we have used Google's reCAPTCHA service. ReCAPTCHA started as a research project out of Carnegie Mellon University in 2007. Google acquired the project in 2009, around the same time that Cloudflare was first getting started. Google provided reCAPTCHA for free in exchange for data from the service being used to train its visual identification...

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.
