Some things I learned about Android's Frame animation

Hi Just a quick share of lessons learned about Android's Frame-by-Frame animations. Some of the functionality is poorly documented, as many people point out, so the web is the only place for answers. Having looked for some answers to these questions and couldn't find any - here's what I found out myself. Update [2/3/11]: A …

10 lines-of-code OCR HTTP service with Python, Tesseract and Tornado

Screen shot 2011-01-25 at 12.32.27 PM

Hi I believe that every builder-hacker should have their own little Swiss-army-knife server that just does everything they need, but as a webservice. You can basically do anything as a service nowadays: image/audio/video manipulation, mock-cloud data storage, offload heavy computation, and so on. Tornado, the lightweight Python webserver is perfect for this, and since so …

Number Saver (Android application)

A very basic feature that I was missing in my Android phone is the ability to save a number while I'm in a call. Sure you can go to the home screen, and open up any app with a textbox, but I decided to create a dedicated application. So, meet Number Saver! UPDATE: Number Saver …

I tried to keep it as "casual" as I could and not get into the crevices of every library, instead, I wanted to get results and fast. First, NyARToolkit is a derivative of the wonderful …

iPhone camera frame grabbing and a real-time MeanShift tracker

i_can_has_meanshift

Hi Just wanted to report on a breakthrough in my iPhone-CV digging. I found a true realtime frame grabber for the iPhone preview frame (15fps of ~400x300 video), and successfully integrated this video feed with a pure C++ implementation of the MeanShift tracking algorithm. The whole setup runs at realtime, under a few constraints of …

Qt & OpenCV combined for face detecting QWidgets

As my search for the best platform to roll-out my new face detection concept continues, I decided to give ol' Qt framework a go. I like Qt. It's cross-platform, a clear a nice API, straightforward, and remindes me somewhat of Apple's Cocoa. My intention is to get some serious face detection going on mobile devices. …

So you're trying to get your homemade app on your pwned iPhone

iphone

Recently I was working on an iPhone app for work, for demo purposes, but my company cheaped out on the Apple iPhone Developers registration.  More accurately, the process of binding a multi-million-$-a-year company with Apple Inc. takes a very long time, so we took the back-door and just pwned our test iPhone devices (firmware 2.1). "How hard …
