content: Hi,I'm not a programmer so please bear with me. I was playing around with the version of SeekoOFix that was modified to work with the Seek Pro and also the libseek-thermal by Maarten Vandersteegen.The camera works great with both, but I noticed the image looks markedly better in SeekOFix than it does with libseek-thermal (the adjustable temperature limits notwithstanding), so I was wondering what kind of post-processing SeekOFix does that libseek-thermal does not.I know I could dig through the code and find out, but I know very little of each so that would be fairly involved for me. I'm not looking for in-depth analysis, just wondering what the fundamental differences might be that appear to make the SeekOFix image that much better.Thanks,Rafael

content: As a developer of SeekOFix I can tell you how I did it.It is quite simple:Remove all bad pixels; adjust gain of every pixel; display first frame after shutter calibration...https://github.com/frenkinet/SeekOFix/blob/master/TestSeek/Form1.cs

content: Thanks, that helps a bit. I built the project and poked around the code a bit; it's s a very nice app.Any idea what it would take to build it for Windows Universal?Cheers,R

content: No sure...I have put Win10 on RPI and it did recognise SeekThemal module so I guess it is possible to do it...

content: in fact I just modified some variables and init command in SeekOFix, no extra processing.if you use the internal reference frame,I think the two are the same.but when using the external reference frame,libseek-thermal does some average processing and libseek-thermal seems better than SeekOFix on my computer?

content: Interesting. Using external reference frames, SeekOFix (or rather, your fixed version to work with the Pro) on my computer seems to deliver a much better image (maybe it's the color mapping, but there seems to be much more detail) which is why I'm wanting to use it.I'm trying to get the VS project to build a UWP package that can be deployed on Win 10 IoT; apparently it's supported but I need to get it to run normally first with the Pro modifications.R

content: I've got a couple of SeekThermal cams, both are much the same with the Android app. However they are quite different withhttps://github.com/maartenvds/libseek-thermalCamera1's ffc.png ishttps://www.dropbox.com/s/6488ttflzmfzlad/1ff.jpg?dl=0& it makes good photos. Camera2s ffc.png ishttps://www.dropbox.com/s/6upqsnmq9qwss6d/2ff.jpg?dl=0,it has a circle with flare halo & makes compromised photoshttps://www.dropbox.com/s/c0464prz8xlg4k2/2flare.jpg?dl=0Just wondering what the Android app is doing to deal with the halo that the libseek based C+ code is not?
