求翻译：按图像分辨率由高到低的顺序，第一层分解为16个方向子带，第二层分解为8个方向子带，第三层分解为4个方向子带，第四层为3个子带(不含低频分解系数)。是什么意思？

Descending order according to image resolution, the first layer is decomposed into 16 Fang Xiangzi with the second layer is decomposed into eight Fang Xiangzi with the third layer is decomposed into four Fangxiang Zi with the fourth layer of the three sub- band (excluding low-frequency decomposition

The resolution of the image from high to low in order to break down, and the first-tier sub-band, 16 direction Layer 2 decomposes into 8 directions with Son decomposition, Layer 3 to 4, with 4 sons a direction for Level 3 (excluding low-frequency decomposition with tall factor).

According to the image resolution from high to low order, the first decomposition is 16 direction innertubes, the second decomposition is 8 direction innertubes, the third decomposition is 4 direction innertubes, fourth is 3 innertubes (does not contain low frequency resolution ratio).

The image resolution from high to low order, tier divided into 16 directions, the second layer down to 8 subbands, third level down to 4, the fourth layer 3 subnets (without low frequency decomposition coefficient).

According to picture being from resolution ratio to low order, first floor resolve into lead by 16 direction son, the second floor is resolved into 8 direction sons and taken, the third floor is resolved into 4 direction sons and taken, the fourth floor is for 3 sub tapes (decompose the coefficient
