z****c 发帖数: 602 | 5 关于2,那个小印不会以为Hough transform是O(n)的算法吧,虽然对所有的点只扫一遍

H***e 发帖数: 476 | 8 hough transform这种是图像处理的课里面才有的
根本不是一般cs的基础课 |

O******i 发帖数: 269 | 9 Hough 是数字图像处理课的一个变换方法,我还记得是直线方程变成极坐标方程,离散
化求共线最多的那个格点。不过CareerCup书的标准解法却是用斜率截距结合
hash的简单方法。

电面一:主要是research相关的东西,比如简历上的东西。由于面试官的背景是kalman
filter的,所以问了不少这个问题。另外问了一个Bayesian rule,Gaussian
distribution,sampling method,compressive sensing,bag of words, ransac:
A有两个孩子,问都是男孩的概率,另外如果已知一个是男孩,问另外一个也是男孩的
概率;
如果x是高斯分布,然后问y=2x的分布和y=x^2的分布;
假定有一个data stream,如何uniform sample k个sample;
eigenvalue在corner detection的用处;
little/big endian
电面二:主要是research的问题,比如compressive sensing的各种solver,bagging/

homers and strike out at least 10 batters in the same game. Since 1918, it's
just the second time that a pitcher has thrown at least seven innings and
all five of his hits allowed were homers (fifth overall in the bigs since
that date to have all five hits allowed be homers). The only other Texas
Rangers pitcher to allow five home runs hits as the only hits was Charlie
Hough on June 24, 1989.

s******n 发帖数: 518 | 20 Mont Blanc是在法国,意大利,瑞士3国交界处的一座雪山。海拔并不太高4810 m,但
冰雪覆盖面积不小。我们两口子算不上真正的登山爱好者。一般也就在风和日丽的天气
里走一天。唯一一次在雪上行走的经历是在tuckerman ravine滑野雪,不过连crampons
都没用上。有朋友想在夏天爬Mont Blanc请我们一起去。说是3天训练2天跟向导登顶。
LD欣然同意跟着去凑热闹,我觉得3天训练太耽误功夫也不想辛苦自己,在雪线下溜达
看风景好了。我还查了他们的登山路线,准备跟他们在雪线下走一段。
到了发现所谓3天训练其实只有第一天是教基础知识和技术,继绳子,穿crampon,用冰
斧之类。其余4天1个向导带2人差不多想去哪去哪。登顶要看天气,4天时间机会多些。
有不少人已经不是第一次来了,为了登顶。课程星期一开始,当时的天气预报是从星期
3开始可能有雷雨。朋友高山反应比较厉害,又被第2天要用冰斧攀爬的陡坡吓了一下,
基本放弃了登顶的想法。周3给自己放了一天假。向导带着LD一人先坐缆车到Aigulle
Du Midi。原计划爬另一座较矮的山,走了一阵遇到团里其他人登顶回来,向导问L... 阅读全帖 |

e*******e 发帖数: 6165 | 36 这两个的专业都是『编舞』,而且都是现代舞编舞!! 明显是制作方故意放在一起的
,要是按照刘福洋/沙ga那组的理论,不应该在一起的,不过后期制作把黄潇改成了爵
士舞!!!
首先这个音乐好,有节奏有变换,尼玛要是换成好声音那首寂寞先生,看他们怎么跳。
。。
基本功上来讲,我觉得黄潇更好。编舞真的是倪旺一个人嘛,我怀疑。
但编舞确实做到扬长避短,没有什么高难度动作
唯一看懂了的,就是最后那会儿---村口俩大爷,盼着救星来把全村人解放。。。
最后,看看美版Derek Hough & Alison Holker跳这首曲子吧
看之前我觉得中国版还是不错的,看之后。。。
我不理解为什么金星评价这么高 |

俗话说的好,打蛇打七寸。jimmy show是abc的一个重要节目。对于abc来说,对于
jimmy的实质性惩罚,只会影响自己的生意。因此,向abc抗议,不会有什么实质性的结
果,顶多就是abc出来做过虚假的道歉。jimmy本人,到现在歌照唱,舞照跳,一没道歉
,二没停节目。
那要如何才能让我们的抗议有效呢?我认为最好的办法就是抵制abc的母公司迪斯尼。
大家要让迪斯尼认识到问题的严重性。对于一个服务儿童的商家,能够容许旗下的公司
用儿童之口发出种族大屠杀的言论么?如果迪斯尼不道歉,abc不道歉,jimmy不受到实
质性的惩罚(开除或停节目),那么,迪斯尼就是在暗中支持种族大屠杀。
对于抵制的方式,我认为,对于我们大部分群众来说,主要就是抵制迪斯尼的电视,产

d*****l 发帖数: 8441 | 44 用底层的类似驱动的程序/进程来记录鼠标点的实时运动轨迹(x(t),y(t)),
实质上是将类似圆周运动分解为x和y方向的位移波形。
分析x(t)和y(t)波形之间的相位关系,可判断园周运动的方向。
分析x(t)和y(t)波形之间的幅度和频率关系,可判断偏离园周运动的程度:
例如当两者的幅度频率均相等/近时(等于或近似于1:1),就是圆周运动。
当频率关系为整数倍(>1)关系的时候,就是非常典型的李萨如图形。
图像处理中的Hough变换是静态的,与时间无关。
而要判别顺时针或逆时针的区别,必定少不了与时间相关,所以
记录并使用时间波形是免不了的。 |
