Human pose estimation with Python and Gluoncv

Human pose estimation is something useful for robotics/programming as you can see what position a person is in a picture. For last weekend’s Hackrithmitic I did an experiment for fun using computer vision pose estimation. To start with I found several possibilities with available libraries:

Tensorflow js has been used to say, don’t touch your face, but it takes a massive amount of cpu.
Openpose is a popular one, only licensed for noncommercial research use, and there is a Opencv example for it that doesn’t quite show how to use it.
AlphaPose is supposedly faster and has a more clear license and possibility for commercial use – if you want that as a possibility. I checked out the install instructions and worked but for “python3” instead of “python”. It also misses obvious step of installing cuda for your Nvidia system before running.
GluonCV is another, which seems more user friendly. This one I was able to get running in a few minutes with their example:

The eBook Shuffle

Remember when there were mini mp3 players with one button and a shuffle feature? If like many geeks you have a bunch of interesting ebooks from Humble Bundle, Oreilly or Github or wherever you get technical books, you probably have folders and folders of lots of interesting books. What if you want to “shuffle” or randomly pick one off your virtual bookshelf and read a bit while staying home? Today I’ll show how to virtually “grab a book off the shelf” of your collection with a simple Python script:

Building a Linux App part 7: Building an Installer File

There’s a big difference between having that quick python script set up with a GUI, and having a full desktop or mobile app ready to click install. In this post I’ll show the steps to build a Python script into an installable application.

Building a mobile app for Linux, part 4: GPS/mobile tracking

Another important part of many mobile apps is location tracking – there is, fortunately, there is a built in api for most Linux systems called Geoclue that should work… There is even a Python-geoclue package, but after some digging I found that this package does not work in Python3. In fact it’s hard to find examples or documentation, if you look at the files of the package you can see there are some basic docs:
