Capturing image from webcam in java

Question

How can I continuously capture images from a webcam   I want to experiment with object recognition  by maybe using java media framework     I was thinking of creating two threads  one thread    Node 1  capture live image Node 2  save image as  1 jpg  Node 3  wait 5 seconds Node 4  repeat      other thread    Node 1  wait until image is captured Node 2  using the  1 jpg  get colors from every pixle Node 3  save data in arrays Node 4  repeat

I have used JMF on a videoconference application and it worked well on two laptops  one with integrated webcam and another with an old USB webcam  It requires JMF being installed and configured before-hand  but once you re done you can access the hardware via Java code fairly easily

There s a pretty nice interface for this in processing  which is kind of a pidgin java designed for graphics  It gets used in some image recognition work  such as that link   Depending on what you need out of it  you might be able to load the video library that s used there in java  or if you re just playing around with it you might be able to get by using processing itself

You can try Marvin Framework  It provides an interface to work with cameras  Moreover  it also provides a set of real-time video processing features  like object tracking and filtering   Take a look   Real-time Video Processing Demo  http   www youtube com watch v D5mBt0kRYvk  You can use the source below  Just save a frame using MarvinImageIO saveImage   every 5 second   Webcam video demo   public class SimpleVideoTest extends JFrame implements Runnable       private MarvinVideoInterface    videoAdapter      private MarvinImage             image      private MarvinImagePanel        videoPanel       public SimpleVideoTest            super  Simple Video Test            videoAdapter   new MarvinJavaCVAdapter            videoAdapter connect 0           videoPanel   new MarvinImagePanel            add videoPanel           new Thread this  start            setSize 800 600           setVisible true              Override     public void run             while true                  Request a video frame and set into the VideoPanel             image   videoAdapter getFrame                videoPanel setImage image                       public static void main String   args            SimpleVideoTest t   new SimpleVideoTest            t setDefaultCloseOperation JFrame EXIT ON CLOSE             For those who just want to take a single picture   WebcamPicture java  public class WebcamPicture       public static void main String   args            try              MarvinVideoInterface videoAdapter   new MarvinJavaCVAdapter                videoAdapter connect 0               MarvinImage image   videoAdapter getFrame                MarvinImageIO saveImage image     res webcam picture jpg              catch MarvinVideoInterfaceException e               e printStackTrace

Try using JMyron How To Use Webcam Using Java  I think using JMyron is the easiest way to access a webcam using java  I tried to use it with a 64-bit processor  but it gave me an error  It worked just fine on a 32-bit processor  though

Java usually doesn t like accessing hardware  so you will need a driver program of some sort  as goldenmean said   I ve done this on my laptop by finding a command line program that snaps a picture   Then it s the same as goldenmean explained  you run the command line program from your java program in the takepicture   routine  and the rest of your code runs the same   Except for the part about reading pixel values into an array  you might be better served by saving the file to BMP  which is nearly that format already  then using the standard java image libraries on it    Using a command line program adds a dependency to your program and makes it less portable  but so was the webcam  right

Some time ago I ve created generic Java library which can be used to take pictures with a PC webcam  The API is very simple  not overfeatured  can work standalone  but also supports additional webcam drivers like OpenIMAJ  JMF  FMJ  LTI-CIVIL  etc  and some IP cameras   Link to the project is https   github com sarxos webcam-capture  Example code  take picture and save in test jpg    Webcam webcam   Webcam getDefault    webcam open    BufferedImage image   webcam getImage    ImageIO write image   JPG   new File  test jpg       It is also available in Maven Central Repository or as a separate ZIP which includes all required dependencies and 3rd party JARs

I have used JMF on a videoconference application and it worked well on two laptops  one with integrated webcam and another with an old USB webcam  It requires JMF being installed and configured before-hand  but once you re done you can access the hardware via Java code fairly easily

I believe the web-cam application software which comes along with the web-cam  or you native windows webcam software can be run in a batch script windows dos script  after turning the web cam on i e  if it needs an external power supply   In the bacth script   u can add appropriate delay to capture after certain time period  And keep executing the capture command in loop   I guess this should be possible  -AD

Java usually doesn t like accessing hardware  so you will need a driver program of some sort  as goldenmean said   I ve done this on my laptop by finding a command line program that snaps a picture   Then it s the same as goldenmean explained  you run the command line program from your java program in the takepicture   routine  and the rest of your code runs the same   Except for the part about reading pixel values into an array  you might be better served by saving the file to BMP  which is nearly that format already  then using the standard java image libraries on it    Using a command line program adds a dependency to your program and makes it less portable  but so was the webcam  right
