    "message": "Enhance convergence monitoring in SyN registration\n\n- Added a convergence monitoring feature to the `register_syn_cpp` function, allowing for early stopping based on the cost of the first channel.\n- Introduced a `ConvergenceMonitor` struct to handle the computation of convergence values over a specified window of iterations.\n- Updated the registration process to utilize the convergence monitor, enabling levels to terminate early if convergence criteria are met.\n- Modified the `register_volume3d` function to accept new parameters for convergence threshold and window size.\n- Enhanced tests to validate the new convergence functionality, including checks for various edge cases and expected behaviors.\n- Updated documentation and comments to reflect the new convergence logic and its integration into the registration workflow.\n",
