More Experiments Around RGB Averaging
I decided to replicate the showing/hiding the dominant hues in images with showing/hiding around the average RGB values instead. I created a class called RGBColor (just holds red, green, and blue values), similar to the one I created called HSBColor. I could have used the java.awt.Color class, but that insists on a range of 0-1…

Eliminating the Dominant Hue from an Image
I thought it would be interesting to invert the idea of showing only the dominant hue, and show everything but that instead. I used the exact same code, but inverted the if statement so: if (!hueInRange(hue, lower, upper)) became if (hueInRange(hue, lower, upper)) Effect is as follows, as with most of these, my favourite effect…

Showing Only the Dominant Hue In an Image
Having extracted the dominant hue from the images, we can manipulate the image such that pixels that are not (or close to) the dominant hue are instead made grayscale. I converted to grayscale using the brightness of the image in the HSB. This worked really nicely. From my earlier experiments I decided on a hue…

Extracting Dominant Color: RGB Averaging Doesn’t Work
This makes sense – two colors can have the same R values, but wildly different G and B values. The result of averaging them will bear no relation to the originals. However just to prove it, it was very easy to tweak my code to average the RGB values instead of counting the hues. The…

Extracting the Dominant Color from an Image in Processing
I’ve had an idea in mind for a while now, that requires extracting the dominant color from an image. I had no idea how to do this, and worried it would be really hard. The first thing was extracting the pixels from the image for processing, this was super easy thanks to this handy image…

4 Hours to Smash the CS Stereotype and Create Something Beautiful
Ali and I will presenting our paper 4 Hours to Smash the CS Stereotype and Create Something Beautiful (pdf) at the upcoming CICE Education conference in Toronto. Christine Alvarado of Harvey Mudd college came to Google last month to gave a talk on how they’d brought female enrollment in Computer Science up to 42%. The talk is called “Three…

Sunflower Layout in Processing
For a while, I’ve been wanting to make something that explores color in photo sets. Reading Beautiful Visualization (Amazon), I came across the perfect way to arrange the elements. It imitates the layout of the sunflower seeds, “the most efficient and visually mesmerizing way of packing small elements into a large circle”. I decided to…

Experimenting with a Visual, Activity-Based Curriculum
When I left Ottawa, I had to find the new me to run my Processing Workshop. His name is Ali and he’s awesome. He’s had the idea to write up the ideas into a paper, so we’re working on that at the moment, but it occurred to me that I didn’t write much about it…
