Getting Set Up on Android
→: Getting Set Up on AndroidI used the event Programming Languages I’ve Been Meaning To Try But Haven’t Gotten Around To Yet at the Stripe offices (organised by Star Simpson) in San Francisco to get going on Android. Aside – I love the concept of this event. Great opportunity to hang out with your laptop, the only goal being to suck…

More Experiments Around RGB Averaging
→: More Experiments Around RGB AveragingI 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
→: Eliminating the Dominant Hue from an ImageI 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…

Folders of Images, Compare and Contrast
→: Folders of Images, Compare and ContrastNow I’ve experimented with things, I wanted to make something that would allow me to compare different effects on the same photo, and loop through a folder of pictures looking for nice effects. I overrode mousePressed() to change the image on click. The big challenge here was running out of Java Heap space once I…

My Theory of User Happiness and the Enterprise Application
→: My Theory of User Happiness and the Enterprise ApplicationEnterprise applications are (usually) the applications that people have to use, whereas consumer applications are (usually) those that they choose to use, and so I would argue they are where you can have the biggest effect on user-happiness. Gains in user happiness on consumer applications are mostly incremental – the standard is pretty high, it has to…

Visualising A Photo Series
→: Visualising A Photo SeriesWhenever I’m scrolling through pictures I’ve taken, it seem like they are in sections – here’s when I was near the beach, he’s the park, the night sky and fireworks. I thought if you visualised the way that the dominant colors changed, patterns would emerge. I found the perfect layout for this, the sunflower layout,…

Showing Only the Dominant Hue In an Image
→: Showing Only the Dominant Hue In an ImageHaving 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
→: Extracting Dominant Color: RGB Averaging Doesn’t WorkThis 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
→: Extracting the Dominant Color from an Image in ProcessingI’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…
