CMY(K) color image

CMY (or its variant CMYK) color space uses as primary colors: cyan, magenta, and yellow.
This color space used by printers is interesting because, this is an example of a subtractive color model. When you add color(s), you converge towards black color.

3D curves: the toric solenoids

After learning how to build and display spheres in 3D with ImageJ [see post], this post describes how we can use them for drawing a 3D curve...

Improving the Dissolve effect

In a previous post [Link], the fade-in, fade-out, and dissolve effects were described and computed in ImageJ for static images. Here are two main improvements...

3D models: the sphere

When working in 3D, there is always a need of 3D basic models to try new algorithms or to use them as building blocks. In this post, we'll see how to build a sphere and how we can move it in 3D without any additional plugins.

Using images as arrays in script

In my previous posts Using arrays in script... [TOC],  we have seen in Part 1 how to store data in arrays using the built-in function newArray(...)  and in Part 2, the use of Table windows (Results [Link] or any Table window [Link]). Here I'll describe how data storage can be done via images and how this technique is powerful for large arrays.

Fade-in, Fade-out, Dissolve video effects

When working on videos (stacks in ImageJ), it is always interesting to make transitions between video clips to finalize a small movie .... and that's possible with ImageJ.

The sieve of Eratosthenes

Finding prime numbers is a good exercise to improve your skills in the programming scripting language of ImageJ. Moreover, that's a good opportunity to use a 2D image as a temporary array.
