how haarcascade_frontalface_alt2.xml is used in jviolajones project

 jviolajones is well open-source project based java. but now i encountered confusion, because instruct is different with haarcascade_frontalface_default.xml and haarcascade_frontalface_alt2.xml, Detector.java does not support this. is there a new way to support?

not able to run from program

Hi
I am able to run the face detection from command line but not from my java 
program. I gave the correct path for picture as well as .xml files. But it 
gives the error 

Exception in thread "main" java.lang.NoClassDefFoundError: 
org/jdom/input/SAXBuilder
    at detection.Detector.create(Detector.java:35)
    at faceDetection.main(faceDetection.java:16)

Could you please help me to solve this problem.

Thanks in advance,

Some .xml files created by OpenCV can not be loaded.

What steps will reproduce the problem?
1. Train a file using OpenCV (see attachment).
2. Try to load the file using Detector.create().


What is the expected output? What do you see instead?

Expected output: 
Nothing, file loads normally.

Actual output: 
Program crashes with null pointer exception: 
Exception in thread "main" java.lang.NullPointerException
    at detection.Detector.<init>(Detector.java:52)
    at detection.Detector.create(Detector.java:41)

Errors Loading OpenCV xml files

What steps will reproduce the problem?
1. Try to construct Detector using other OpenCV xml files (e.g. 
haarcascade_eye.xml)

What is the expected output? What do you see instead?
Expected to load the xml file and use its contents for object detection.  
Exception occurs when reading the file.  See stack trace below.

NOTE: ViolaJonesFilter is a class I have created that wraps and uses the 
Detector, Effect, Rect and Stage classes internally.  The same error can be 
seen using the original source.

Code is PERFECT but not well commented

What steps will reproduce the problem?
1. Go through the source code in the trunk folder in the SVN

What is the expected output? What do you see instead?
expect to see comments within the functions explaining the lines of code
Instead, I only see comments explaining the parameters of the functions and the 
outputs of the functions which is not explanatory.

What version of the product are you using? On what operating system?
jViolaJones2.0, windows xp

Please provide any additional information below.
I wish to understand Viola Jones through your java implementation, however your 
code is not well commented and I have a hard time to understand your design 
decisions.

Running it in GPU?

Checked source code, can't see how it's being executed in GPU as mentioned in 
the project home page, is it misunderstanding?

getFaces method also takes BufferedImage as input

Hi

In the scenario of taking a picture with the webcam and loading it as 
BufferedImage, it was difficult to analyze that image without saving it as a 
file. This diff attempts to solve that.

If you would like to take a look at the small diff, please find it attached.

Best regards,
Cristian

Passing jdom.Element instead of a filename

It would be good to pass a jdom.Element into the detector routine instead of a 
filename, which would allow a single cascade file load in the case when you 
want to run detection on multiple images.

Using jviolajones on android app.

Is there a way to use the jar file on android application? Because android does 
not support "java.awt.Rectangle"

Thanks and you are doing a great work!
