O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
Portability
OpenCV was designed to be portable. It was originally written to compile across Borland C++, MSVC++, and the Intel compilers. This meant that the C and C++ code had to be fairly standard in order to make cross-platform support easier. Figure 1-6 shows the platforms on which OpenCV is known to run. Support for 32-bit Intel architecture (IA32) on Windows is the most mature, followed by Linux on the same architecture. Mac OS X portability became a priority only after Apple started using Intel processors. (The OS X port isn't as mature as the Windows or Linux versions, but this is changing rapidly.) These are followed by 64-bit support on extended memory (EM64T) and the 64-bit Intel architecture (IA64). The least mature portability is on Sun hardware and other operating systems.
If an architecture or OS doesn't appear in Figure 1-6, this doesn't mean there are no OpenCV ports to it. OpenCV has been ported to almost every commercial system, from PowerPC Macs to robotic dogs. OpenCV runs well on AMD's line of processors, and even the further optimizations available in IPP will take advantage of multimedia extensions (MMX) in AMD processors that incorporate this technology.
