Hi I'm trying out Affdex sdk for emotion detection from a webcam feed. Each frame is fed to a FrameDetector as shown in examples. But after few seconds, the nothing gets detected. Not even the face. The same set up works for PhotoDetector. I have correctly set up the timestamp (as was shown in one of the examples). I'm using this on Ubuntu 16.04 using C++
Any ideas as to why this behaviour?
Thanks.
FrameDetector initialized with 5 frame buffer.

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?

try updating graphics card drivers
I am in win7 x64 Pro
Kinect xbox 360 is connected and samples (openNI and NITE) run well. When i use Processing 2.1, sketch with kinect run without error notification but there nothing on screen and he is gray or white... Yet all simple processing samples (without kinect) run well...What is wrong? I'm disappointed
intalled :
OpenNI-Win32-1.5.7-Dev.msi
NITE-Win32-1.5.2-Dev.msi
SensorKinect093-Bin-Win32-v5.1.2.1.msi
SimpleOpenNI 1.96
KinectSDK-v1.7
Ms Visual Studio 2012
Processing 2.1
I tried
OpenNIx64-1.5.7-Dev.msi
NiTE-Windows-x64-2.0.0
Sensor-Win64-5.1.6.6
but I have same problem
kinect run well (all samples from openNI and Nite) but whith Processing 2.1 (or 2.0.3 and 1.5.1) It still doesn't work : nothing on screen (gray or white) without notification error.
All simple processing samples (without kinect) run well...
Thank you for your help
I would recommend that you use the J4K (Java for Kinect) library in Processing. J4K is an open-source library and communicates with the native Microsoft Kinect SDK. You can download the j4k-processing.zip from here: j4k-processing.zip
There is a Green-Screen example in the examples folder (you need to unzip the j4k-processing.zip) called example5_basicAugmentedReality. This example shows you in the middle of a simple 3D virtual scene. In addition there are other examples for 2D interaction, reading the values of the accelerometer, etc.
Try to use SimpleOpenNI 0.27 on Processing 1.5.1
You can download SimpleOpenNI 0.27 from this link
if it didn't solve your problem. You should write more detail about your system that you use such as the version of SimpleopenNI, Kinect driver, etc
I used until yesterday afternoon a Kinect for XBOX 360 on my computer, a MacBook Pro 15" Late 2011, whose specifications are available here. I use Windows 7 (natively installed, without using virtual machines). The version of the SDK I had installed was 1.0.
All of a sudden, from today the Kinect no longer worked. Initially I thought it was some error in my code, but I noticed that the program remained stuck at the beginning, when I called the method KinectSensor.Start().
I started looking for information on the internet. I read about a solution obtained by reinstalling the drivers. It did not work, and then I tried to install version 1.6 of the SDK. Unfortunately, even that did not work.
I've seen at this stage, there might be compatibility issues with certain USB host controllers, such as the Intel 5 Series/3400 Series Chipset USB host controller. In my case, however, there should be no problems (because there were not ever been up to yesterday):
To check if the problem was really due to the sensor, and not to my application, I run one of the test applications provided with the SDK, called Kinect Explorer. However, I encountered the same problem with this test application. After waiting about one minute, when the Kinect Explorer starts I cannot see neither the color stream, nor the depth stream, nor information about skeleton. The only thing I can do is move the Kinect up and down, changing the angle of the neck. Even the microphone array seems to work properly.
I read two interesting posts about this kind of problem: this and this, which have not been answered.
In the first of these two links, the user who reports the problem says that the hardware has been compromised. I thought the same thing myself until I started again Kinect Explore, initially with the sensor unplugged. Once started this program, I plug-in the cable, and I noticed that Kinect Explorer has marked the Kinect sensor as Connected. After a short initialization phase, I again see the color stream, while the depth stream showed an image of uniform color (green-gray):
This situation lasted a few seconds, after which the image is locked and the question came up. Also, sometimes the FPS value drops from 30 to 29.
I am able to reproduce this latter situation only after keeping the Kinect unplugged for a while (10 minutes are sufficient).
How can I solve this strange and terrible problem? Is it possible to restore the Kinect sensor, and make it works again? Or do I have to conclude that the sensor is irretrievably broken?
I trying capturing the image in video mode from Canon Digital Camera IXUS 75 model using WIA type. But I didn't get any thing. If Photo mode, I can seen digital Camera storage data i.e., video,photos etc. So, is it required any .dll file or any stuff for capturing image in video mode. Even I tried different way's also
Using JavaCV.It detects Webcam,Laptop internal Camera.But it doesn't detect digital Camera device.
JTWAIN is not supported with windows 64-bit OS. So, I didn't tried with this.
Please help me. Either Canon digital camera software nor Java relevant stuff.
Assuming you still plan to use Java and if the problem is still an issue, I used Asprise's JTwain to get image from scanner, camera (not only laptop web cam) and etc. The only thing you need are the drivers for the devices. Grab an eval version from Asprise and check this step by step dev guide here. As far as I understood, this should be good enough for your requirements.
By the way, seeing the file structure of a camera does not always mean you have the device fully working.
I tried using "Kinect for Windows" on my Mac. Environment set-up seems to have gone well, but something seems being wrong. When I start some samples such as
OpenNI-Bin-Dev-MacOSX-v1.5.4.0/Samples/Bin/x64-Release/Sample-NiSimpleViewer
or others, the sample application start and seems working quite well at the beginning but after a few seconds (10 to 20 seconds), the move seen in screen of the application halts and never work again. It seems that the application get to be unable to fetch data from Kinect from certain point where some seconds passed.
I don't know whether the libraries or their dependency, or Kinect's hardware itself is going wrong (as for hardware, invisibly broken or something), and I really want to know how to detect which is it.
Could anybody tell me how can I fix the issue please?
My environment is shown below:
Mac OS X v10.7.4 (MacBook Air, core i5 1.6Ghz, 4GB of memory)
Xcode 4.4.1
Kinect for Windows
OpenNI-Bin-Dev-MacOSX-v1.5.4.0
Sensor-Bin-MacOSX-v5.1.2.1
I followed instruction here about libusb: http://openkinect.org/wiki/Getting_Started#Homebrew
and when I try using libfreenect(I know it's separate from OpenNI+SensorKinect), its sample applications say "Number of devices found: 0", which makes no sense to me since I certainly connected my Kinect to MBA...)
Unless you're booting to Windows forget about Kinect for Windows.
Regarding libfreenect and OpenNI in most cases you'll use one or the other, so think of what functionalities you need.
If it's basic RGB+Depth image (and possibly motor and accelerometer ) access libfreenect is your choice.
If you need RGB+Depth image and skeleton tracking and (hand) gestures (but no motor, accelerometer access) use OpenNI. Note that if you use the unstable(dev) versions, you should use Avin's SensorKinect Driver.
Easiest thing to do a nice clean install of OpenNI.
Also, if it helps, you can a creative coding framework like Processing or OpenFrameworks.
For Processing I recommend SimpleOpenNI
For OpenFrameworks you can use ofxKinect which ties to libfreenect or ofxOpenNI. Download the OpenFrameworks packaged on the FutureTheatre Kinect Workshop wiki as it includes both addons and some really nice examples.
When you are connecting the Kinect device to the machine, have you provided external power to it? The device will appear connected to a computer by USB only power but will not be able to tranfer data as it needs the external power supply.
Also what Kinect sensor are you using? If it is a new Kinect device (designed for Windows) they may have a different device signature which may cause the OpenNI drivers to play-up. I'm not a 100% on this one, but I've only ever tried OpenNI with an XBox 360 sensor.
