# The Eight Queens Problem2

Today I want to tackle a classic algorithm puzzle known as the Eight Queens Problem. In this problem, your task is to arrange eight queens on a chessboard so that none of the queens is attacking any... 続きを読む >>

# Variation on Connected Objects – Using Graphs

Reader Uri Pe'er found an old post from 2011 about shortest paths in binary images, and he asked this follow-up question (paraphrased):How can I determine if there is a path from one row to another... 続きを読む >>

# Variations on Connected Objects – Using imfill

Reader Uri Pe'er found an old post from 2011 about shortest paths in binary images, and he asked this follow-up question (paraphrased):How can I determine if there is a path from one row to another... 続きを読む >>

# Logical indexing3

One of my favorite aspects of MATLAB for image processing is how I can use a binary image to index directly into a grayscale image. The technique is called logical indexing, and I'm going to show you... 続きを読む >>

# Gaussian filtering with imgaussfilt2

With the R2015a release a couple of years ago, the Image Processing Toolbox added the function imgaussfilt. This function performs 2-D Gaussian filtering on images. It features a heuristic that... 続きを読む >>

# Aliasing and image resizing – part 34

Today I'll try to wrap up my discussion about how aliasing affects image resizing and about how the imresize function tries to prevent it. (This is called antialiasing.) Let me show you where we are... 続きを読む >>

# Aliasing and image resizing – part 27

In my 03-Jan-2017 post, I introduced my new topic: aliasing, especially as it relates to resizing images. Today I will get more specific about what aliasing actually is.I'll use a 1-D sequence to... 続きを読む >>

# Aliasing and image resizing – part 1

Happy New Year!I'm going to kick off 2017 with two or three posts about antialiasing. Specifically, I will discuss what antialiasing means in the context of image resizing, and I will explain how the... 続きを読む >>
