Euler number calculation with spots

Since the small spots in the slices were not completely removed, the calculation of the Euler number was incorrect. Therefore, taking Sr30 as an example, we provide the original liquid phase, the liquid phase after removing noise, and the three-phase data of the noise. After recalculating the Euler number, we confirmed that the calculation error was caused by the noise.The noise removal operation can be performed in ImageJ as follows:​​Process > Noise > Remove Outliers​​, with parameters set to ​​Radius=5​​ and ​​Threshold=0.50

由于切片中的微小斑点未被完全清除，导致欧拉数（Euler number）的计算结果出现偏差。因此，本研究以Sr30为例，提供了原始液相数据、去噪后的液相数据以及含噪三相数据。经重新计算欧拉数后，我们确认该计算误差确由噪声引发。可通过ImageJ软件按以下标准步骤执行去噪操作：处理 > 噪声 > 去除异常值，参数设置为Radius=5与Threshold=0.50。
