This week I worked really hard on trying to fix my marker tracking program as since the lighting conditions had changed it didn't work well enough yet. After a lot of effort and doing pointless stuff I realised I just had to change saturation. I also figured out a kind of way to keep track of these movements. I also added some more errors and binding conditions for it to work a bit more better. I also tried to find best constants and directions for In the end the two programs worked together quite okay. So next I am going to try to use kinect camera. Depending on how well I can attach it to my program I can maybe start working on depth informationt

This week I spent a lot of time trying to find a Java library that could interact with Kinect2. Sadly most of the libraries had been discontinued after Kinect1. I did find a J4K librayry that lets the user read the depth and color information. However using this the input data is a byte array which is slow in conversion to the data type that opencv uses. Also the Imshow module does not diplay everything properly. So for now my solution would be to write something in concern to that. Also I have realised that the fact that I am using Java is seriously slowing down my progress.
Also spent bigger part of friday test-solving the problem that Andres made for Armen.

This week went by quite fast. First part of the week I tried to get my program too work with kinect as I had finally figured out some haphazard way to connect them. However while testing it I discovered that Kinect randomly shuts down and starts up again during quite short intervals. Thus making it kind of inusable. I also noticed that the color ranges of my markers had changed in comparison to the webcamera. Since I'm waiting for my new computer I spent some time on using opencv already implemented method to find mouthcorners in the greyscale image. I also spent some time on homework
