    \end{figure}

    The second phase involves image pre-processing and augmentation. Roboflow, a developer framework for computer vision procedures, will be used for image pre-processing and annotation. The annotated images will be uploaded to a dataset and Roboflow will apply the pre-processing and augmentation processes to the dataset. Also, Roboflow will apply annotation corrections to ensure that the annotations were correctly made.

然而，此行有一个Underfull \hbox (badness 1199)警告：

我尝试使用 microtype 和 emergencystretch，但它们无法消除 underfull 错误。我该如何消除此警告？非常感谢您的帮助。谢谢！
