Week 6 Friday (Presentation Day)

The Internship has finally come to an end, so these blogs will be coming to an end now as well. I had a great time with my fellow interns, who were all really fun to be around.

Thank you to Joe Pow for having the CIS Internship program and for running the hockey analytics lab. You helped us overcome all the problems we faced during our research.

Now for next year's interns: make sure you find a more expensive place to go to lunch when the imaging science center is paying for it. Start at the most expensive place and work your way down. Then, take advantage of this exceptional meal which you earned with some great negotiating. Make the best out of this opportunity.

Week 6 Wednesday and Thursday

On Wednesday, we went out for lunch on CIS's tab. Then, we had our mock presentation, and our presentation seemed to go pretty smoothly, so there weren't many corrections to make.

On Thursday, I went over the presentation by myself, practicing my lines and fine tuning anything I though wasn't clear enough. Overall, we are done for Friday.

Week 6 Tuesday (Presentation)

     Hockey Analytics Lab

We practiced our presentation today. I will need to change the wording of a couple of slides, in order to explain the challenges we faced and the manual components. Otherwise, it went quite smoothly and we look prepared for Friday.

Week 6 Monday (Presentation)

We spent a lot of time in the morning going through the presentation. First, we did a complete practice run, where Joe timed how long it went. After giving us some general comments, we went through slide by slide, adding in some information and reminding ourselves of certain comments we must make in order to ensure that the story is complete and clear.

I changed one of the screenshots into a video, and I edited appropriately. I also redid the calculations for player identification in order to not account for the numbers on the sleeves, as Joe warned that those are not clear enough to use. I made a couple other edits, but now it is just back to practicing. 

Week 5 Friday (Power Point)

I presented the Power Point in the morning to Joe, and we found a few kinks that needed to be worked out. I cut the videos appropriately, and then I reorganized those slides to have better flow. We made some more changes to the conclusion slides as well. After, that it was just reading it through.

Week 5 Thursday (Power Point)

    

We went over the power point in a pseudo presentation this morning. Emma and I realized that we needed to add more speaker notes, and we also found a couple of places where the story gets choppy and needs reorganizing or additional slides.

I also filled in some gaps that we had in our presentation. I added in some broadcast film, as well as fixed focal length camera film into our introduction. We plan on using that information in order to explain the differences between the two systems.

Joe also found a power point that showed image translation very well in one of the slides. I will use that slide in order to depict that translation, as it appropriately explains what the freshman did.

After adding in some more speaker notes, we should be ready to do a full on presentation practice. 

Week 5 Wednesday (Powerpoint)

I spent time working on adding images to the player identification portion of the power point today. I also went through the screenshots I used to find out what percentage of the players were in the broadcast frame on average. I realized that I accounted for the goalie as well, so I recalculated those measurements, and I added in more frames. I ended up finding that 56 percent of the players were in each frame.

Now, Emma, Joe, and I will simply work to ensure the legitimacy of our player tracking comparisons. 

Week 5 Tuesday (Powerpoint)

The next few days will be spent just working on putting the rest of the information and images into my power point. I went over a lot of the research that we did to make sure we covered everything we needed to have covered to tell a complete story. Any gaps will also arise as we make the power point.

I am completely done with putting information in bullets into the slides. Now, I will find the corresponding images to help explain those bullets. Then, I will need to really practice and make sure I have everything I need there.

Week 5 Monday (Powerpoint)

I spent the majority of my time working on the presentation and mainly organizing my thoughts as to what progress we have made over the past four weeks. I looked through the power point that the freshman made, and the image above was in that power point. It clearly depicts the placement of the cameras and what portions of the hockey rink that they each capture. We will use this image in our presentation, as that information is something we definitely need to convey.

There was other valuable information in that power point, which we will apply to our presentation. Other than that, I input information into the presentation, and I will add the images later. Some of the bullet points will need to be taken out, but I want to keep them for now to practice with.

Week 4 Friday (Research Symposium)

I spent the majority of the day at the research symposium. There was a poster presentation, where I saw presentations on anything from 3d printed prosthetic to the radar detection that we see in the image above. The presentations were all very interesting and in-depth, making it challenging to understand everything that was written on their boards. However, it was easy to see the purpose and progress of the individual researchers. I also gained some valuable knowledge I can utilize in my presentation in a couple of weeks.

There was some in person presentations that I witnessed as well. They were on the relationship between space matter density and star production as well as the merging of the stars. This one was very hard to understand, but all three researched gave different presentations on the issue with some overlap.

When I came back to the lab, I spent some time looking into MNIST, but now my next focus is just on confirming whether or not pixels are the best thing to use to compare the broadcast system and the fixed focal length system. I am waiting for a response back from Mike, but I will continue working on the power point in the meantime.

Week 4 Thursday (Finalizing Data)

I had to analyze the data from the previous two days. I did this by finding the average number of pixels in each clipping that could be used to find the jersey number. I did this for the broadcast system and the fixed focal length camera system. After compiling the data, I found that on average there were about 209 more pixels per frame for the broadcast system. However, after closer inspection, it became clear that this difference was due to a multitude of 0 pixels in the fixed focal length system, potentially due to the angle of the camera. Comparatively, there were almost no situations in which 0 pixels were present for the broadcast system.

However, only 50 percent of the hockey players were in each frame, so this trade off must be accounted for in the final analysis of which system is better for player analysis. Now, I will work more on my power point presentation, but if any problems arise with the accuracy of the data, I will have to refer back to my calculations.

Week 4 Wednesday (Testing)

After working out the kinks in the method of comparison yesterday, today was simply spent working on finding and analyzing the data. I took about 30 frames from the set of fixed focal length camera data that is not filtered. The filtered data is what the RIT freshman had used to calibrate the system, so the numbers on the back of the jerseys are visible to the human eye. Using that data would inherently have skewed the data, making it seem like there are more pixels revealing jersey number than there really are.

Thus, I utilized the unfiltered data. I ended up using the clippings of other teams. This decision should not matter as the numbers are placed in the same location, and for our pixel analysis, should not vary based on team. I used the bounding polygon box on Image J and searched how Image J can find the area inside the box. Pressing [M] allows numerous data values to be shown in a results window. One of those data values is the area. I finished calculating the pixel values for the broadcast and fixed focal length camera systems for 30 frames each. Now, I will determine if that is sufficient data and the differences between the two systems.
