Question about intersect function

[ChenjieXu]

I don't think it is correct to determine if two regions are intersected by comparing their bounding boxes.
For example, the following situation does not apply. Could anyone help me with this please? Thanks in advance.

你好，我非常开心发现你和我遇到了相同的看法
我修改了insection函数，考虑了欧氏距离

def intersect(a, b):
    set_a = set(a["position"])
    set_b = set(b["position"])
    for (y1, x1) in set_a:
        if (y1 + 1, x1) in set_b or (y1 - 1, x1) in set_b or (y1, x1 + 1) in set_b or (y1, x1 - 1) in set_b:
            return True
    return False

其中position包括当前区域的所有位置（y1,x1）,(y2,x2)……
