Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

I want to identify a qr code with side 2 cm from any position with hololens Camera but after a few test with an application the qr code has to be at least 3 cm large to be identified.
So i tryed to acquire photo with Camera and process the images with web Qr decoder like ZXing library but the image are saved in .jpg so i think that are compressed, Is possible to have the raw images??
An other question is if i calibrate the camera of the Hololens the quality of the image increase??
I found this github project to do it https://github.com/qian256/HoloLensCamCalib
Someone has other possible solutions to increase the quality of the acquired image??

Thank you for your help,
