Stegdetect通过统计测试来分析图像文件中是否包含隐藏内容，它运行静态测试以判断隐藏的内容是否存在。此外，它还会尝试识别隐藏内容是通过哪个隐写工具嵌入的。(Stegdetect uses statistical tests to analyze whether the hidden content is contained in the image file, and it runs a static test to determine whether the hidden content exists. In addition, it will also try to identify the hidden content embedded by which steganography tool.

If the test results show that the file may contain hidden information, Stegdetect will use 1~3 stars to identify the possibility of hidden information after the test results. The 3 stars indicate that the existence of hidden information is the most likely.)
