Be sure to match up the left hand edges. The right side will have an overhang. Pin the top, bottom and left hand edges together neatly. On the right hand side (or opening of your pillowcase), the base piece will have a large overhang (about 12cm or 5â).
What is OpenCV? OpenCV is the leading open source library for computer vision, image processing and machine learning, and now features GPU acceleration for real-time operation. OpenCV is released under a BSD license and hence itâs free for both academic and commercial use. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android.
OpenCV has been around since 2001. In those days the library was built around a C interface and to store the image in the memory they used a C structure called IplImage. This is the one youâll see in most of the older tutorials and educational materials.
