Building Computer Vision Projects with OpenCV 4 and C++

OpenCV and the data revolution in computer vision

OpenCV existed before the data revolution in computer vision. In the late 1990s, access to big amounts of data was not a simple task for computer vision researchers. Fast access to the internet was not common, and even universities and big research institutes were not strongly networked. The limited storage capacities of personal and bigger institutional computers did not allow researchers and students to work with big amounts of data, let alone having the computational power (memory and CPU) required to do so. Thus, the research on large-scale computer vision problems was restricted to a selected list of laboratories worldwide, among them MIT's Computer Science and Artificial Intelligence ...
