Today I want to wrap up (for now) my series on multiresolution pyramids by showing you how to make this strange-looking fruit: This a slightly nontraditional demonstration of a technique... read more >>

Does this line of code make you raise your eyebrows in puzzlement?c = sum(A,[1 2]) If so, you are likely an experienced MATLAB user who does not make a habit of carefully studying the release notes,... read more >>

In my April 2 post, I introduced multiresolution pyramids, and I explained my dissatisfaction with the function impyramid, which (sadly) I designed. (Aside: I had that post ready to go on April 1,... read more >>

Last time, I talked about the function impyramid and how I have been dissatisfied with it. (Confession: I designed it.) Today I want to present an alternative approach to creating a multiresolution... read more >>

There's a function in the Image Processing Toolbox that I'm not especially fond of: impyramid.I shouldn't tell you who designed this function, but I'll give you a hint: his initials are "Steve... read more >>

I was noodling around recently with a future blog topic (multiresolution pyramids; stay tuned) when I was reminded of a recent addition to MATLAB: the function imtile, introduced in R2018b.This... read more >>

An Image Processing Toolbox user recently reported to us good results for using makecform and applycform to convert colors from sRGB to CMYK. Here's the code they used:c =... read more >>

Today's blog post is dedicated to everyone whose eyes aren't as young as they used to be.In last week's blog post on pursuit curves, I showed this figure: If you ran my code exactly as I posted it,... read more >>

Here's an interesting snippet I learned while working on today's blog post: Mathematician Jacob Bernoulli asked for a logarithmic spiral to be engraved on his tombstone. Here's an example of a such a... read more >>

Update: See my 20-Dec-2019 post for how to write APNG files from MATLAB. Have you heard of animated PNG (APNG) files? Are you interested in creating them from MATLAB? They are supposed to be... read more >>
