No.004：Median of Two Sorted Arrays

问题: There are two sorted arrays nums1 and nums2 of size m and n respectively.Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). Example1:nums1 = [1, 3]nums2 = [2]The median is 2.0Example2:nums1 = [1, 2]n…

[LeetCode] Find Median from Data Stream 找出数据流的中位数

Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Design a d…

[LeetCode] Median of Two Sorted Arrays 两个有序数组的中位数

There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 这道题让我们求两个有序数组的中位数,而且限制了时间复杂度为O(log (m+n)),看到这个时间复杂度,自然而然的想到了应该使用二分查找法来求解.但是这道题…

Applying vector median filter on RGB image based on matlab

前言: 最近想看看矢量中值滤波(Vector median filter, VMF)在GRB图像上的滤波效果,意外的是找了一大圈却发现网上没有现成的code,所以通过matab亲自实现了一个,需要学习的朋友可以拿过去用.本文的核心是VMF的matlab实现,最后通过在RGB图像上应用举例说明. VMF的数学表达: 含有N个矢量的集合{C1,C2,...CN},它的VMF结果如下所示: 其中,CVM1表示距离所有其他向量的距离和最小的那个向量.而距离可以自己定义,常用的欧氏距离,曼哈顿距离等等.…

【leetcode】Median of Two Sorted Arrays

题目简述: There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 解题思路: 这本身是个很简单的题目,但是题目要求他的复杂度为O(log(m+n)),就很有难度了.不过首先我们还是可以明确我们要用分治法.关键是怎么分治呢?我们…
