A Christmas present to myself this year: rebuild my desktop into a Hackintosh… Ever since I gave into Lightroom and started using my macbook for photo editing, I had been missing my desktop’s larger monitor and faster processor. Since I can’t run Lightroom on Linux, and since I can’t stand booting into Windows, the only … Read more
Audio Frequency Spectrum Analyzer & Spectrogram As a followup to a previous post on Music Visualization with Processing (and a good excuse to play with my Arduino), I decided to convert my Processing music visualizer into hardware. The project is not finished yet, but I wanted to post a quick update and how-to on making what … Read more
I got the privilege of developing some of the Super Computing 2012 (SC12) booth demos for AccelerEyes, to showcase ArrayFire. Above is an ArrayFire demo running at SC12 on an nVidia GPU. This demo (source code HERE) uses OpenCV to capture webcam video and processes the stream in several different ways, in real-time. From top-left to bottom-right: Sobel filter, ArrayFire logo, Motion (frame differencing), Source image, Histogram … Read more
It has been many years since my first bike video, and today I finally get to publish my second one. My acquisition of a GoPro HD Hero 960 earlier this year motivated me to finally get around to making a new BMX video (though I am ashamed that I had never made any other videos until now!). This second … Read more
Shameless plug (It’s my blog though), but I’m truly being honest when I say: I use FeedSpeak every single day. FeedSpeak has become such a part of how I get my news and updates, that I don’t know what I would do without it. Of all the things I have worked on, be it software … Read more
On a whim, I decided to make a word cloud of all the content on my blog, as of the evening of Sept 17, 2012 (dating back to June 30, 2010). Word clouds are fun and very easy to make with services such as Wordle (though I happened to have used IBM Word Cloud Generator in this case). I … Read more
About one year ago, I wrote about a simple example of Image Processing with LibJacket + OpenCV… and the trend continues today. In this post, I demonstrate how ArrayFire (an improved version of LibJacket) can easily interop with OpenCV, through a simple example of unsharp maksing (local contrast enhancement). Program Flow: Capture steaming webcam … Read more
I recently upgraded my phone from a Motorola Droid X to a Samsung Galaxy S3 (finally!), and WOW what a difference! Below is a giant chart comparing the two phones, but first I’ll list some random thoughts about owning and using the GS3. Not surprisingly, everything about the Galaxy S III is just amazing! When … Read more
At the beginning of this year, I decided (at the last minute!) to embark on a “take a photo every day” journey. I had never done anything like it before, and thought it would be a fun way to learn and practice photography (i’m still a n00b). At first, to ensure I make good use of … Read more
This is something I’ve been meaning to do for years: make a real chain necklace from one of my old broken bmx bike chains. Well, I finally got around to cleaning off all the grease, shortening it to the right length, and of course, using a paperclip as the latch 🙂 . This goes well … Read more
