i'm using oracle database .. actually i try diff things but dont know what happening ?? data is also copied into the string variable .. is der any problem while using prepare stmt or statement .. actually m accepting values from text and then inserted to the database ..

need help bro .. thanks in advance

when i'm trying to inserting my data into my database the data in not inserted is der any prblm ?? code:

try
{
    String name=jTextField1.getText();
    String stream=jTextField2.getText();
    String classes= jTextField3.getText();
    String roll_no=jTextField4.getText();
    InputStream inputStream = new FileInputStream(new File(filePath));
    InputStream inputStream1 = new FileInputStream(new File(filePath1));

//stmt.executeUpdate("insert into student_regestration values( "+name+",'"+stream+"','"+classes+"',"+roll_no+")");
    String sql = "insert into student_regestration values( ?,?,?,?,?,?)";
    pstmt = con.prepareStatement(sql);

    pstmt.setString(1, name);
    pstmt.setString(2, stream);
    pstmt.setString(3, classes);
    pstmt.setString(4, roll_no );

    pstmt.setBlob(5, inputStream);
    pstmt.setBlob(6, inputStream1);

    pstmt.executeUpdate();

    System.out.println("Inserted");
}
catch(Exception ex)
{
        System.out.println("Not entered" + ex);
//JOptionPane.showMessageDialog(this," Message: "+ex.getMessage());
}

yes thanks

when i'm using this code its not working

Error: identifier expected for extractor and detector

Thanks is advance

public class CompImg {

    //Load images to compare

Mat img1 = Highgui.imread("d:/capture1.jpg", Highgui.CV_LOAD_IMAGE_GRAYSCALE);

Mat img2 = Highgui.imread("d:/capture1.jpg", Highgui.CV_LOAD_IMAGE_GRAYSCALE);

MatOfKeyPoint keypoints1 = new MatOfKeyPoint();

MatOfKeyPoint keypoints2 = new MatOfKeyPoint();

Mat descriptors1 = new Mat();

Mat descriptors2 = new Mat();

//Definition of ORB keypoint detector and descriptor extractors

FeatureDetector detector = FeatureDetector.create(FeatureDetector.ORB); 

DescriptorExtractor extractor = DescriptorExtractor.create(DescriptorExtractor.ORB);

//Detect keypoints

detector.detect(img1, keypoints1);

detector.detect(img2, keypoints2);  

//Extract descriptors

extractor.compute(img1, keypoints1, descriptors1);

extractor.compute(img2, keypoints2, descriptors2);

//Definition of descriptor matcher

DescriptorMatcher matcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE_HAMMING);

//Match points of two images

MatOfDMatch matches = new MatOfDMatch();

matcher.match(descriptors1,descriptors2 ,matches);

}

Break can you help me more ?? i have many question related to my project, and i'm using opencv which is new for me .. or we cam talk on mail .. Thanks

ohh m sorry bro thanks a lot .. its working

it will not giving any error message but video is stop and also face detection is not work, exception msg is print Erro: method subrect(rect) , variable frame of type mat

Thanks break for reply but its not working .. now it will not taking any snapshot .. or cam also not visible .. Error: Mat cropped = frame.subrect(rect);
