我正在使用 CVI 做我的最终项目，但我遇到了一些问题。该项目一般是在图像上应用FFT，在四个级别（通道）添加高斯白噪声，应用IFFT来恢复原始图像。我有两个部分：

  1. 我可以对行和列使用 2DFFT 或 1DFFT
  2. 我必须对行和列使用 1DFFT，并将信号通过滤波器 2D-DWT

现在我用一个名为 bitmapID 的指针保存图像数据，该指针只能用于某些功能。我想将图像数据保存为一个数组，以便我更容易访问它并进行操作。我尝试使用函数 ImaqImageToArray，但我不知道它为什么不起作用（与图像尺寸有关的东西）

我想得到一些帮助提前谢谢

这是我一直在尝试的一些事情：
