# Local maxima, regional maxima, and the function imregionalmax

A recent algorithm discussion on the Image Processing Toolbox development team reminded me of something I originally wanted to do a long time ago: explain imregionalmax and some related operations.... 더 읽어보기 >>

# Use less meshgrid and repmat2

The functions meshgrid and repmat have a long and rich history in MATLAB. Today, I'll try to convince you to use them less.meshgridThe function meshgrid is typically used to take a vector of... 더 읽어보기 >>

# Use imbinarize to Threshold Gray-Scale Images

Today, I want to convince you to use imbinarize instead of im2bw.Background: I recently saw some data suggesting that many Image Processing Toolbox users are still using im2bw, an old function that... 더 읽어보기 >>

# NaN Sightings2

Some of us at MathWorks like to share our "NaN sightings." Here is an example to show what I mean. This is a screenshot of the tuner/metronome app that I use when practicing music. One day, I was a... 더 읽어보기 >>

# How to Use a Custom Interpolation Kernel with imresize2

Recently, I was talking with MathWorks writer Jessica Bernier about the reference page for the imresize function. Jessica pointed out that we don't have an example that shows how to use your own... 더 읽어보기 >>
