研究方向
Examine the imglab source code in dlib/tools/imglab/ to understand the current event handling and UI architecture. Look for any existing undo/redo infrastructure or comments about it. Review the issue comments for any maintainer input (currently none). Research the Command design pattern for implementing undo/redo in C++ GUI applications. Consider starting with a simple history stack for operations like moving or resizing bounding boxes.
