Week 4

During this week Hamlet and I continued to work on grabbing the position of the threshold object whenever a specific button was pressed. We first had to figure out how to track the object that was displayed. Once we figured that out it was simple to capture the positioning at the press of a button. The only problem with the thresholding program is that it can only track one image at a time. We also got the contour boxes to go around the object of choice. However because this program only thresholds and tracks one image at a time we needed to find another that would be more helpful. 
We were assigned to watch a video where a man worked with Visual Basic on taking a picture and then the program would match the image and moving object from the camera. We had to convert the code from Visual Basic to C++. We finally got the program to run properly and were able to take a picture of whatever we wanted and have the camera match and track the image. This program worked well until it came upon images without corners. I tried to create a picture with a paw print, heart, and check mark, but it was grabbing the points and couldn't really focus on the rounder parts of each object. So we tried another program.

I believe the third program works with SURF as well. This program ran very smooth as well. It grabbed the important points in the picture that was projected on screen. It could grab multiple objects, which was a plus, however we needed to have it grab objects that were in a certain vicinity. This was just grabbing objects that seemed important to it. For instance it was circling my pupil, iris, and eye. It also had a very long range.

During this week we also had a meeting with everyone who was working on the project. Whether they were on Skype or in the meeting room. We talked about different pieces that could represent the objects at hand. Questions were brought up about how big the map size should be, who were prospective candidates for testing the new simulation, what types of materials would be used for the objects, and more. This was about a two hour-long meeting with many different questions, concerns, and variables that were brought up.  We now have new goals for next week and will hopefully be moving to a new lab so that we can better test our simulations.

Finally During the week I got to take the objects that Matt had made and test them in the SURF program that detected main features. Also creating contrast between the pictures with their original and then making a black and white. There were major feature detection increases from the original picture to the black and white picture. This was a pretty simple way to end the week.
