OpenCV is considered to be one of the best Open Source Computer Vision and machine learning software libraries. It helps developers build complete projects on image processing, motion detection, and image segmentation. OpenCV for Python enables you to run computer vision algorithms smoothly in real time, combining the best of the OpenCV C++ API and the Python language. This book covers the following exciting features: * Handle files and images, and explore various image processing techniques * Explore image transformations like translation, resizing, and cropping * Gain insights into building histograms * Brush up on contour detection, filtering, and drawing * Work with augmented reality and 3D visualization frameworks * Work with machine learning, deep learning, and neural network algorithms If you feel this book is for you, get your [copy](https://www.amazon.com/dp/1789344913) today! https://www.packtpub.com/ ## Instructions and Navigations All of the code is organized into folders. For example, Chapter02. The code will look like the following: ``` channels = cv2.split(img) eq_channels = [] for ch in channels: eq_channels.append(cv2.equalizeHist(ch)) ``` ## Code Testing Specifications *Mastering OpenCV 4 with Python* requires some installed packages, which you can see next. * Chapter01 (*Setting Up OpenCV*): ``opencv-contrib-python`` * Chapter02 (*Image Basics in OpenCV*): ``opencv-contrib-python matplotlib`` * Chapter03 (*Handling Files and Images*): ``opencv-contrib-python matplotlib`` * Chapter04 (*Constructing Basic Shapes in OpenCV*): ``opencv-contrib-python matplotlib`` * Chapter05 (*Image Processing Techniques*): ``opencv-contrib-python matplotlib`` * Chapter06 (*Constructing and Building Histograms*): ``opencv-contrib-python matplotlib`` * Chapter07 (*Thresholding Techniques*): ``opencv-contrib-python matplotlib scikit-image, scipy`` * Chapter08 (*Contours Detection, Filtering, and Drawing*): ``opencv-contrib-python matplotlib`` * Chapter09 (*Augmented Reality*): ``opencv-contrib-python matplotlib`` * Chapter10 (*Machine Learning with OpenCV*): ``opencv-contrib-python matplotlib`` * Chapter11 (*Face Detection, Tracking, and Recognition*): ``opencv-contrib-python matplotlib dlib face-recognition cvlib requests progressbar keras tensorflow`` * Chapter12 (*Introduction to Deep Learning*): ``opencv-contrib-python matplotlib tensorflow keras`` * Chapter13 (*Mobile and Web Computer Vision with Python and OpenCV*): ``opencv-contrib-python matplotlib flask tensorflow keras requests pillow`` Make sure that the version numbers of your installed packages are equal to, or greater than, versions specified below to ensure the code examples run correctly.
