On the Mac, it seems the only way to access OpenCV, short of writing a C/C++ library that currently doesn’t exist, is via python. Image acquisition, from camera to our application, is about 100ms for each frame (or at least, that’s the goal).We need 3-4fps processing speed (preferably a bit more, just to give some headroom).

The primary goal of my work this week is to put together a simple benchmarking app for both Mac and Windows, to see which methods of image processing work best with the massive images we’re using, and which CPUs are faster across a variety of machines. Since my original post, we have decided to try building this on the mac, but may revert to Windows if it ends up we need more speed and have to custom build a PC. It’s soul destroying to spend 27 months of your life building an application and to see it disappear into the deep dark depths of the App Store. Unless you’ve got funding or a solid marketing plan, I wouldn’t recommend anyone else attempt this on their own.I can use a Xojo console application and shared memory declares to do this without, but that is actually more work. I had to tweak it to get maximum performance. This part was actually way easier than I anticipated, the first draft of the plugin worked on the very first run. This way I can take advantage of multi-core processors, sharing the raw image data between each thread. when combining the individual exposures into a 128-Bit floating point HDR, I actually use a custom built Xojo plugin (written in Objective-C and utilizing GCD). They regret the change, because now they’re no longer in control.

I know of a very talented developer who wrote their own GPU based image processing library for the Apple platform, they got fed up with each OS update breaking their library, so they switched to using Apple’s… Only to find that it gets frequently broken also.

Or 10.14 just fails to render certain images with certain filters. Or Apple’s GPU based image editing is supposed to support tiling, so that it can process large images on lesser machines, except that’s broken for macOS 10.13, whereby it renders one tile and then gives up. Not to mention that to do work on the GPU requires the use of OpenGL or Metal, both have issues on different version of the macOS.

If I had access to the code that loads images, I could fix it, I don’t. For instance macOS 10.14 doesn’t handle certain 16-Bit images correctly and on load will produce a corrupted image.

I hope MS have a far better quality control than Apple, because our app features many workarounds for different versions of the OS, whereby functionality is broken or doesn’t work right. Relying on third parties to support their frameworks is a recipe for disaster. As someone who’s done something very similar using Xojo for the Mac ( ).
