error: no suitable method found for predict(Mat)

[hokage4]

Hi,
i make project face recogntion and build it by gradle but when i build i have this error

home/project/hipi/examples/jcvhd/src/main/java/org/hipi/examples/HelloWorld.java:132: error: no suitable method found for predict(Mat)
int predictedLabel = faceRecognizer.predict(testImage);

• What went wrong:
  Execution failed for task ':examples:jcvhd:compileJava'.

Compilation failed; see the compiler error output for details.

can any one help me please.

It looks like that method was renamed to "predict_label" for some reason:

thank you i used predict_label and work successfully but i want Get the prediction with confidence.
predict_label not return confidence

[hokage4]

i want use this method to get confidence FaceRecognizer.predict(Mat,IntPointer,DoublePointer) if can.

or advise me if you have another way to get confidence
thank you

Yes, we can use that method. What is the issue?

[hokage4]

I used it in this way

Mat testImage = imread("//home//project//NetBeansProjects//newjavacv//aa.jpg"  , CV_LOAD_IMAGE_GRAYSCALE);
int predictedLabel = 0;
double con = 0.0;
faceRecognizer.predict(testImage, predictedLabel, con);

and the build.gradle is

jar {
  manifest {
    attributes("Main-Class": "org.hipi.examples.HelloWorld")
  }
dependencies{
compile project(':core')
compile group: 'org.bytedeco', name: 'javacv', version: '1.2'
compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.3.2'

}
from {
    configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
configurations {
    all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
    
}
}

and when i build it by gradle i have the this error

no suitable method found for predict(Mat,int,double)
faceRecognizer.predict(testImage, po, distance);
              ^
    method FaceRecognizer.predict(Mat,IntPointer,DoublePointer) is not applicable

How can solve this error ?

As per the commit above, I've fixed the call in the samples. Just do it the same way.

Thanks for reporting!
