我有一个像素数据的numpy数组，类似
0 0 0 0 0 0 0
0 1 3 4 6 1 0
0 2 3 5 2 1 0
0 1 0 0 1 0 0
0 0 0 0 0 0 0
我想得到一个新的数组，它排除任何带有零的外部行/列，所以我最终只得到非零值（适用于任何给定的数组），即
1 3 4 6 1
2 3 5 2 1
到目前为止我所得到的只是
1 3 4 6 1
2 3 5 2 1
1 0 0 1 0
使用 np.argwhere 查找“最小”和“最大”非零值，但这仍然包括具有零和非零值的行/列。

[0, 2, 3, 5, 2, 1, 0],
[0, 1, 0, 0, 1, 0, 0],
[0, 0, 0, 0, 0, 0, 0]])
首先，我们要删除那些全零的行和列。
delete_rows = (data == 0).all(axis=1)
delete_cols = (data == 0).all(axis=0)
现在，让我们将这些行设置为
-999data == 0data[delete_rows, :] = -999
data[:, delete_cols] = -999
接下来，让我们找到包含 any 零并且位于要删除的行旁边的所有行（上一个 或 下一行位于
delete_rowszero_rows = (data == 0).any(axis=1)
d_r = np.zeros(zero_rows.shape, dtype=bool)
d_r[1:] = d_r[1:] | delete_rows[:-1]
d_r[:-1] = d_r[:-1] | delete_rows[1:]
d_r[0] = d_r[-1] = True
delete_rows = delete_rows | (zero_rows & d_r)
data[delete_rows, :] = -999
我们可以重复此操作，直到
delete_rowsdel_count = sum(delete_rows)
prev_del_count = del_count + 1
while del_count != prev_del_count:
zero_rows = (data == 0).any(axis=1)
d_r = np.zeros(zero_rows.shape, dtype=bool)
d_r[1:] = d_r[1:] | delete_rows[:-1]
d_r[:-1] = d_r[:-1] | delete_rows[1:]
d_r[0] = d_r[-1] = True # First and last rows can be deleted if they have any zeros
delete_rows = delete_rows | (zero_rows & d_r)
prev_del_count, del_count = del_count, sum(delete_rows)
data[delete_rows, :] = -999
然后，我们可以对列做同样的事情：
del_count = sum(delete_cols)
prev_del_count = del_count + 1
while del_count != prev_del_count:
zero_cols = (data == 0).any(axis=0)
d_c = np.zeros(zero_cols.shape, dtype=bool)
d_c[1:] = d_c[1:] | delete_cols[:-1]
d_c[:-1] = d_c[:-1] | delete_cols[1:]
d_c[0] = d_c[-1] = True # First and last cols can be deleted if they have any zeros
delete_cols = delete_cols | (zero_cols & d_c)
prev_del_count, del_count = del_count, sum(delete_cols)
data[:, delete_cols] = -999
现在，我们有：
delete_rows = np.array([ True, False, False, True, True])
delete_cols = np.array([ True, False, False, False, False, False, True])
我们可以过滤出所需的行和列：
filtered_data = data[~delete_rows, :][:, ~delete_cols]
给出：
array([[1, 3, 4, 6, 1],
[2, 3, 5, 2, 1]])
在更大的数组上运行这个，我们得到了期望的结果：
def remove_outside_zeros(data):
delete_rows = (data == 0).all(axis=1)
delete_cols = (data == 0).all(axis=0)
data[delete_rows, :] = -999
data[:, delete_cols] = -999
del_count = sum(delete_rows)
prev_del_count = del_count + 1
while del_count != prev_del_count:
zero_rows = (data == 0).any(axis=1)
d_r = np.zeros(zero_rows.shape, dtype=bool)
d_r[1:] = d_r[1:] | delete_rows[:-1]
d_r[:-1] = d_r[:-1] | delete_rows[1:]
d_r[0] = d_r[-1] = True
delete_rows = delete_rows | (zero_rows & d_r)
prev_del_count, del_count = del_count, sum(delete_rows)
data[delete_rows, :] = -999
del_count = sum(delete_cols)
prev_del_count = del_count + 1
while del_count != prev_del_count:
zero_cols = (data == 0).any(axis=0)
d_c = np.zeros(zero_cols.shape, dtype=bool)
d_c[1:] = d_c[1:] | delete_cols[:-1]
d_c[:-1] = d_c[:-1] | delete_cols[1:]
d_c[0] = d_c[-1] = True
delete_cols = delete_cols | (zero_cols & d_c)
prev_del_count, del_count = del_count, sum(delete_cols)
data[:, delete_cols] = -999
return data[~delete_rows, :][:, ~delete_cols]
