New Tracking Algorithms, TLD, MedianFlow, and More!

kwatters's picture

So, in OpenCV 3.x there is a new opencv_tracking module that is exposed via JavaCV. 

This module contains 7 different implementation of object trackers.  There is a new "Tracker" filter that allows you to switch between any of these 7 tracking algorithms.  It should work pretty similar to how the lk tracking works in that it should publish the point that's being tracked.  Right now the filter only supports tracking a single point.

MarySpeech on Raspberry Pi

XRobots's picture

I'm finding that MarySpeech takes a while to start up on a Raspberry Pi - at least a minute before it starts working. Also sometimes the speech is broken up if other things are going on like setting digital pins using an Arduino and the MRL service.

I also tried to install destival and use localSpeech but that is just silent, not sure what I've missed. Does anyone have any tips or anything else that's working?

 

thanks

In a Nutshell :-


Virtual Joysticks are Un-Breakable ! .. (mostly)

It took "too" long, but I got virtual Joysticks working ! ...  
To be precise, any device (joysticks, gamepads, keyboards, touchpads, .. etc) which the Joystick service can see can now be "virtualized".

Ok, so what the hell does that mean ? :)

Working code for OpenCv/LKOptical tracking

XRobots's picture

I have my Raspberry Pi and Picam working now, thanks for all the help on that. I'm now trying to get some simple vision stuff working. I've managed to do face tracking and get the bounding box variables returned to the code using this example:

http://myrobotlab.org/service/OpenCV

However it's a bit heavy for the Raspberry Pi, and essentially I just need optical flow, so the LKOpticalTrack filter looks ideal. I can make it work int he Gui - it tracks points fine and I can speifcy the point to track in the code as per the example also which works fine.

Love Robo and MRL

For the past few months, Robo has been getting all my attention.  My wife and kids had to take a back seat while I made Robo strong, smart, and handsome.  I know he is not much of an Android yet, but MRL provides many features out of the box which are so neat!  For instance, the vision powers up, the wksr comes up with programAB, and then the servos power up.

hello i am new to the world of myrobotlab and programing and i have a question about the chatbot ...i installed myrobotlab via the inmoov tutorial that i am now constructing...at first i installed everything with the 32 bit java version ....the chatbot was answering my questions and all....i noticed that i was running a 64 bit windows version ...so i installed the 64 bit java version....then the chatbot stoped answering ...????
