研究方向
Examine the JavaCV API for replacements of cvLoad and the constants CV HAAR FIND BIGGEST OBJECT and CV HAAR DO ROUGH SEARCH. Check the repository's examples or the OpenCV migration documentation. The affected file is FaceApplet.java. The goal is to update the code to compile with the current version of JavaCV.
