所有代码块都经过Python 3.9 + PyWavelets 1.4.1实测，参数值附带物理意义解释，比如“level=3”不是随便写的，而是根据图像尺寸和目标特征尺度算出来的：512像素图，每层分解减半，3层后最低频子带剩64×64，刚好匹配人眼对中等尺度结构的敏感区间。
安装后先确认 PyWavelets 版本在 1.0 以上，低版本 wavedec2 的返回结构有差异，waverec2 对系数形状的宽容度也不一样。 验证方式很简单：随便读一张图，运行 pywt.wavedec2 再 pywt.waverec2 ，对比重构结果与原始输入是否逐像素一致。 这个往返测试是后续所有实验的地基。
