i am doing a project using deep learning and for this i need to take pictures from the kinect and evaluate them. My problem is the resolution of the pictures are 640x860. Due to this i wanted to know if ros freekinect or some library can increase the resolution given a yaml file or something like that? Thank you guys and sorry for the english
Im currently working on a project with Kinect one sensor and the camera resolution is 1920x1080.
if i am not wrong you are currently using the old xbox 360 kinect from what i see here.
I have not heard of libraries that can increase resolutiono yet(this does not mean it do not exist)
But my suggestion is to use the latest hardware found in Microsoft Store here. It cost about $150.
Cheers!

The Kinect 2 for Windows is capable of detecting heart rates, but it's not implemented in the SDK. I've found one sample (https://k4wv2heartrate.codeplex.com/), but he has not released the source code for his work.
Have anyone used any open source library for detecting heart beat for Kinect 2 for Windows?
Well, since nobody has answered in 4 days, let me share what I know and see if it helps.
I haven't worked with Kinect 2 yet, nor have looked at its SDK capabilities. But I know that the trick to heartbeat detection lies in the user's image when viewed through a camera with infrared capabilities. When there is a heartbeat, the skin color changes. Try to see if you can make the RGB camera enter that mode, and then simply detect the color changes in the user's skin.
I am very new to Kinect programming and am tasked to understand several methods for 3D point cloud stitching using Kinect and OpenCV. While waiting for the Kinect sensor to be shipped over, I am trying to run the SDK samples on some data sets.
I am really clueless as to where to start now, so I downloaded some datasets here, and do not understand how I am supposed to view/parse these datasets. I tried running the Kinect SDK Samples (DepthBasic-D2D) in Visual Studio but the only thing that appears is a white screen with a screenshot button.
There seems to be very little documentation with regards to how all these things work, so I would appreciate if anyone can point me to the right resources on how to obtain and parse depth maps, or how to get the SDK Samples work.
The Point Cloud Library (or PCL) it is a good starting point to handle point cloud data obtained using Kinect and OpenNI driver.
OpenNI is, among other things, an open-source software that provides an API to communicate with vision and audio sensor devices (such as the Kinect). Using OpenNI you can access to the raw data acquired with your Kinect and use it as a input for your PCL software that can process the data. In other words, OpenNI is an alternative to the official KinectSDK, compatible with many more devices, and with great support and tutorials!
There are plenty of tutorials out there like this, this and these.
Also, this question is highly related.
I am using the Kinect 2 with the newest available SDK version 2.0. Everything works except IR, tested it with both SDK infrared demo example and Kinect Studio, both result in a black screen. I also looked at the code and capturing Kinect IR frames does not result in any errors, it just consists of all minimum values.
This is quite weird, as I thought IR was used to calculate depth and I can successfully read depth information. Also, I checked (with my cellphone camera) that the IR emitter is turned on and off correctly, just data is not received correctly for some reason.
After encountering the problem I made a fresh install on another computer, as I suspected I had broken my system somehow. I got exactly the same results after installing Kinect SDK. Everything except infrared works.
Has anyone seen this kind of behaviour before?

I am trying to do some work using Kinect and the Kinect SDK.
I was wondering whether it is possible to detect facial expressions (e.g. wink, smile etc) using the Kinect SDK Or, getting raw data that can help in recognizing these.
Can anyone kindly suggest any links for this ? Thanks.
I am also working on this and i considered 2 options:
Face.com API:
there is a C# client library and there are a lot of examples in their documentation
EmguCV
This guy Talks about the basic face detection using EmguCV and Kinect SDK and you can use this to recognize faces
Presently i stopped developing this but if you complete this please post a link to your code.
This is currently not featured within the Kinect for Windows SDK due to the limitations of Kinect in producing high-resolution images. That being said, libraries such as OpenCV and AForge.NET have been sucessfuly used to detected finger and facial recognition from both the raw images that are returned from Kinect, and also RGB video streams from web cams. I would use this computer vision libraries are a starting point.
Just a note, MS is releasing the "Kinect for PC" along with a new SDK version in february. This has a new "Near Mode" which will offer better resolution for close-up images. Face and finger recognition might be possible with this. You can read a MS press release here, for example:
T3.com
The new Kinect SDK1.5 is released and contains the facial detection and recognition
you can download the latest SDK here
and check this website for more details about kinect face tracking
This question relates to the Kaggle/CHALEARN Gesture Recognition challenge.
You are given a large training set of matching RGB and Depth videos that were recorded from a Kinect. I would like to use the Kinect SDK's skeletal tracking on these videos, but after a bunch of searching, I haven't found a conclusive answer to whether or not this can be done.
Is it possible to use the Kinect SDK with previously recorded Kinect video, and if so, how? thanks for the help.
It is not a feature within the SDK itself, however you can use something like the Kinect Toolbox OSS project (http://kinecttoolbox.codeplex.com/) which provides Skeleton record and replace functionality (so you don't need to stand in front of your Kinect each time). You do however still need a Kinect plugged in to your machine to use the runtime.
