@LeegoYih 一个想法,不知道实施起来会不会省时间。比如你给的实例这个情况,其实只有两个不同大小的菱形,
1. Feature Matching 匹配第一个后算出大概尺寸
2. resize 你的目标进行 template matching ,
3. 把 template matching 到的所有都 mask 掉
4. 回到 step 1 继续找
@cnsdytedison Hive 跟 Spark 应该相对多一些把

feature matching 检测到之后直接 mask 掉 match ,继续在图片中找

@eDeeraiD0thei6Oh 在多伦多 20W 挺可以了,温哥华的话应该住房成本会高一些

Replied to a topic by badacook Python pandas 行筛选
没注意是筛选行,那应该这样 df[df.apply(lambda r: r.str.contains('b', case=False).any(), axis=1)]

Replied to a topic by liquorppp MySQL 构建 SQL 查询语句的疑问
@wanv1171 应该是 group by C, B

第一步 over 之后应该也可以直接 group by
