intensity(Regions, Image ::: Mean, Deviation)Regions(输入对象)：在此区域内计算特征。这些区域是从图像中分割出来的一部分或多部分，通常是感兴趣区域（ROI, Regions Of Interest）。
Image(输入对象)：单通道图像，通常是指灰度图像。它可以是多种类型的单通道图像，包括但不限于字节类型 (byte)、方向类型 (direction)、循环类型 (cyclic)、整型 (int1, int2, uint2, int4) 或浮点型 (real)。
Mean(输出控制)：一个区域的平均灰度值。如果输入的 Regions 是一个数组，则 Mean 也会是一个数组，其中每个元素对应于输入区域数组中的一个区域的平均灰度值。
Deviation(输出控制)：区域内灰度值的标准偏差。与 Mean 类似，如果输入的 Regions 是多个区域，则 Deviation 也会是一个数组，其中每个元素对应于输入区域数组中的一个区域的灰度值标准偏差。
