Sliding Window Minimum Implementations

Sliding Window Minimum Implementations. Sliding window minimum is an interesting algorithm, so I thought I would implement it in a bunch of different languages. This repository contains (or will contain) implementations of the algorithm in different programming languages. What follows is an explanation of the problem and the algorithm.

Sliding window min/max – Algorithms and Problem Solving

So, the sliding minimum at a position is the minimum of a block of w elements from current position to the right and the minimum of a block of w elements from current element to the left. So, we can divide the array into [n/w] blocks. Then we can find min in left while traversing from left …

Sliding Window Maximum – LeetCode

Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position.

Sliding window minimum/maximum in 2D – Stack Overflow

Sliding window minimum/maximum in 2D. We need to find all local maximums (or minimums) in the matrix using the sliding window. It means that if a pixel has a minimum (maximum) value compared to all pixels in a window around it then it should be marked as minimum (maximum). There is a well-known sliding window minimum algorithm which finds local

The sliding window minimum algorithm – Richard Harter’s World

The sliding window minimum (maximum) problem runs as follows: We are given a vector V of numeric values of length n and a window size, k. Produce a vector R containing the minimum seen in a window as it slides over the vector V.

Minimum over a sliding window – Stack Overflow

Is there specific algorithm that allows me to maintain a min/max over a small/medium sized sliding window (typical size is 600, with all elements being integers)? The window is really the last N observations in a stream.

Sliding window minimum/maximum algorithm – Project Nayuki

This program uses the sliding window algorithm to compute a minimum or maximum filter on a color image. First, a copy of the image is made and converted to grayscale. Next, each intermediate pixel is set to the value of the minimum/maximum grayscale value within the given radius and distance metric.

Sliding Window Maximum (Maximum of all subarrays of size k)

Sum of minimum and maximum elements of all subarrays of size k. Window Sliding Technique; Maximum possible sum of a window in an array such that elements of same window in other array are unique; Number of subarrays whose minimum and maximum are same; Maximum sum of lengths of non-overlapping subarrays with k as the max element.

Sliding Window Minimum | Programming Praxis

The sliding window minimum problem takes a list of n numbers and a window size k and returns a list of the minimum values in each of the n−k+1 successive windows.For instance, given the list {4, 3, 2, 1, 5, 7, 6, 8, 9} and a window of size 3, the desired output is the list {2, 1, 1, 1, 5, 6, 6}.

Find maximum of minimum for every window size in a given

Lengths of windows for which the elements are minimum are {7, 3, 2, 1, 7, 1, 2}. This array indicates, first element is minimum in window of size 7, second element is minimum in window of size 3, and so on. Create an auxiliary array ans[n+1] to store the result.

Sliding window minimum and maximum filter – MathWorks

Basically, I am attempting to correct an image with uneven illumination by applying a sliding window minimum filter on the image and then finding the illumination or shading function, by applying sliding window maximum filter on on the output of the minimum filter.
