Issue: Error Opening Face Recognition Program Using C#

I have written a face recognition program using C#, but when I try to open the program, I get an error.

The code that the program failed on is:

CascadeClassifier cascadeClassifier = new CascadeClassifier("haarcascade_frontalface_alt_tree.xml");

The error message is:

Emgu.CV.Util.CvException: 'OpenCV: cv::XMLParser::parse'

I have searched the error online, but have not found a solution. I have also tried the following code, but it did not work:

private static readonly CascadeClassifier Classifier = new CascadeClassifier("haarcascade_frontalface_alt_tree.xml");
// or
private readonly CascadeClassifier Classifier = new CascadeClassifier("haarcascade_frontalface_alt_tree.xml");

How can I solve this issue?

The error message indicates that OpenCV is having trouble parsing the XML file for the cascade classifier. One possible solution is to check that the XML file is in the correct location and that the file path is correct in the code. Another solution is to try using a different XML file for the cascade classifier or downloading a new copy of the file from a trusted source.
