How to use ObjectFinder, Stitcher, etc. with SURF on Android #214

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

I have problems running ObjectFinder on Android. 

this is my code:

{

double[] dstCorners;

ObjectFinder objFinder = new ObjectFinder(object);

dstCorners = objFinder.find(image_1);

}

it produece the error:

" java.lang.RuntimeException: java.lang.RuntimeException: 
/home/saudet/android/OpenCV-2.4.0/modules/legacy/src/features2d.cpp:77: error: 
(-213) OpenCV was built without SURF support in function void 
cvExtractSURF(const CvArr*, const CvArr*, CvSeq**, CvSeq**, CvMemStorage*, 
CvSURFParams, int)"

What version of the product are you using? On what operating system?
Eclipse (Android 3.0 or newer): 

Please provide any additional information below.

I'll have to check later, but maybe one of the modules are not loading 
properly.. Does it change anything if you add 
`Loader.load(opencv_nonfree.class)` before using ObjectFinder?

Original comment by samuel.a...@gmail.com on 9 Jul 2012 at 3:11

GoogleCodeExporter commented 9 years ago 
I want to add 'Loader.load(opencv_nonfree.class)` 

but it show that the method "load" is undefined

so I try to rewrite my code as:

vodi func()
{

         int w1,h1;
         int w2,h2;

         String root = Environment.getExternalStorageDirectory().toString();
         Log.d("my tag ","root=" + root);

         Bitmap bmp1 = BitmapFactory.decodeFile(root+"/kkc/3.jpg"); 
         Bitmap bmp2 = BitmapFactory.decodeFile(root+"/kkc/2.jpg"); 

         if(bmp1  == null)
         {
                Log.d("my tag", "It's null");

         }
         if(bmp2  == null)
         {
                Log.d("my tag", "It's null");

         }

         w1 = bmp1.getWidth();
             h1 = bmp1.getHeight();  
         w2 = bmp2.getWidth();
             h2 = bmp2.getHeight();  

         Log.d("my tag ","Load Image");

         IplImage object = IplImage.create(w1, h1, IPL_DEPTH_8U, 4);
         IplImage object_1 = IplImage.create(w1, h1, IPL_DEPTH_8U, 1);

         bmp1.copyPixelsToBuffer(object.getByteBuffer());
         cvCvtColor(object, object_1, CV_BGR2GRAY);
         Log.d("my tag ","cvCvtColor");

         IplImage image = IplImage.create(w2, h2, IPL_DEPTH_8U, 4);
         IplImage image_1 = IplImage.create(w2, h2, IPL_DEPTH_8U, 1);

         bmp2.copyPixelsToBuffer(image.getByteBuffer());
         cvCvtColor(image, image_1, CV_BGRA2GRAY);
         Log.d("my tag ","cvCvtColor");

         Log.d("my tag ","Load Image");

     load(opencv_features2d.class); 
         double[] dstCorners;
         ObjectFinder objFinder = new ObjectFinder(object);

         dstCorners = objFinder.find(image_1);

}

Finally, I get same error >"<

And what if you replace `load(opencv_features2d.class)` by 
`load(opencv_nonfree.class)` ?

I have just released JavaCV 0.2. Do you still have problems with that release? 
Or has this issue been fixed?

Original comment by samuel.a...@gmail.com on 22 Jul 2012 at 12:44

GoogleCodeExporter commented 9 years ago 
thanks for your help 

but,there are stll errors

it show 

"java.lang.NoClassDefFoundError: com.googlecode.javacv.ObjectFinder$Settings"

I found out one of Issues abput "objectfiner"

You gave someone an instructions

*BEFORE* following the instructions in the README.txt file: 
1. Remove BaseChildSettings.class and BaseSettings.class from 
javacv.jar 
2. Follow the instructions in the README.txt file 
3. In your project, define empty classes BaseChildSettings and 
BaseSettings under the com.googlecode.javacv package name 

SO I have to obey these instruction?

The library could be placed on the false postion?

}

It reduces the error

Any luck with this yet? I'm getting the same error and 
'load(opencv_nonfree.class)' doesn't seem to help. I'm having the very same 
stack trace when trying to execute cvExtractSURF(). Please comment if any 
update.

Hi, guys, if you still have this problem please check the following link:
https://groups.google.com/forum/#!topic/javacv/uuBToveMmOQ

I searched the Internet and I have solved this problem, If you want to use 
objectfinder in Android using Javacv please do as follows:
1、do what samuel said as follows:
BEFORE* following the instructions in the README.txt file:
>         1. Remove BaseChildSettings.class and BaseSettings.class from
>         javacv.jar
>         2. Follow the instructions in the README.txt file
>         3. In your project, define empty classes BaseChildSettings and
>         BaseSettings under the com.googlecode.javacv package name
2、import the following package in your project:
import com.googlecode.javacpp.Loader;
import com.googlecode.javacv.cpp.opencv_features2d;
import com.googlecode.javacv.cpp.opencv_nonfree;
3、use Loader.load(opencv_nonfree.class); in your code before you do the 
following

         MyObjectFinder objFinder = null; 
         MyObjectFinder.Settings objectFinderSettings = null; 

         try { 
                objectFinderSettings = new MyObjectFinder.Settings();
                objectFinderSettings.setObjectImage(object); 
                objFinder = new MyObjectFinder(objectFinderSettings); 

} catch (Exception e) { 
                      e.printStackTrace(); 
 } 

and then you can use objFinder.find(img) to compare 2 images.

I tried 2 days and finally solved it. feeling good!

Can anyone confirm that it fixes issues with the Sticher and other things using 
SURF as well?

The fix has been included in the latest release of JavaCV 0.8. Thanks for your 
cooperation! The stitching module should also be working as well now.

A lot of things have changed with this release, so please make sure to read
