Mastering OpenCV 4 - Third Edition

By: Roy Shilkrot, David Millán Escrivá

Overview of this book

Mastering OpenCV, now in its third edition, targets computer vision engineers taking their first steps toward mastering OpenCV. Keeping the mathematical formulations to a solid but bare minimum, the book delivers complete projects from ideation to running code, targeting current hot topics in computer vision such as face recognition, landmark detection and pose estimation, and number recognition with deep convolutional networks. You’ll learn from experienced OpenCV experts how to implement computer vision products and projects both in academia and industry in a comfortable package. You’ll get acquainted with API functionality and gain insights into design choices in a complete computer vision project. You’ll also go beyond the basics of computer vision to implement solutions for complex image processing projects. By the end of the book, you will have created various working prototypes with the help of projects in the book and be well versed with the new features of OpenCV4.

Example comparative performance test of algorithms

As an example, we will set up a scenario where we are required to align overlapping images, like what is done in panorama or aerial photo stitching. One important feature that we need to measure performance is to have a ground truth, a precise measurement of the true condition that we are trying to recover with our approximation method. Ground truth data can be obtained from datasets made available for researchers to test and compare their algorithms; indeed, many of these datasets exist and computer vision researchers use them all the time. One good resource for finding computer vision datasets is Yet Another Computer Vision Index To Datasets (YACVID), https://riemenschneider.hayko.at/vision/dataset/, which has been actively maintained for the past eight years and contains hundreds of links to datasets. The following is also...
