Dan Brooks- PitchFX: Sounds Great, Now Where Do I Get It?
Discussions about the ever-growing segment of “PitchFX analyst.” Dan Brooks will answer questions regarding how the interested fan, sportswriter, or scout can access the PitchFX data with little to no computer expertise, what they can get out of the data, and what areas this method of accessing PitchFX data can hope to improve.
Matt Lentzner- PITCHf/x and Pitching Models
A review about physical pitching models, how arm angles determine pitch attributes, and how it relates to PITCHf/x. Some new ideas and avenues of investigation for the future.
Paul Robinson- Using PitchFX to Teach Physics
We will present some basic physics problems that interest our students, see if we can encourage someone to build a web interface to data set for physics educators, and make a plea to continue to allow free access to the data set for physics teachers.
Greg Moore- Obtaining Hit F/X Data
The past, present, and future of capturing Hit F/X data. I’ll show how Sportvision captures the initial velocity of a batted ball by using Pitch F/X video, as well as the steps that we have scaled to arrive at the current level of automated hit ball tracking.
Harry Pavlidis- What’s That Pitch Worth?
Abstract: Measuring the value, or run value, of a pitch is not a new undertaking, but it has been progressing since Joe P. Sheehan’s series at Baseball Analysts in 2008. Harry Pavlidis will discuss the various ways at arriving at a pitch’s value, in particular, two emerging models.
A quick review already published Hit f/x based metrics for pitchers and batters and a demonstration of the ways in which Hit f/x can improve all fielding metrics.
Dave Allen- Creating Contour and ‘Heat Map’ Graphs to Display PITCHf/x Data
How to create contour maps with the PITCHf/x data to show how a dependent variable. Dave Allen will present two simple methods for fitting a surface to PITCHf/x data, discuss the pros and cons of these methods and mention some more sophisticated methods.
Alan Nathan- Combining HITf/x with Landing Point Data
Some examples of things we have already learned from such an analysis. He will then investigate the question as to how well HITf/x data alone can predict the landing point and hang time.
Matt Thomas- Using Photogrammetry to Track Fielders
The projective transformation of close-range photogrammetry is used with high-resolution digital photography to determine the initial on-field positions of non-battery fielders, as well as the on-field positions at which batted balls are fielded or first strike the turf. Application is made to over 2000 plate appearances from over twenty-five MLB games hosted by the St. Louis Cardinals at Busch Stadium III. Analysis of results is presented.
Rick Swanson- Reaction Over Range (R/R)
In 2010, baseball plans to introduce FIELDf/x. This will allow cameras to measure the distance every fielder moves on every play. Reaction Time will be determined from when the bat and ball make contact until the ball either lands in a glove, the ground, or the wall.
Ron Antinoja- Tendencies in Context
Depending upon the context, players and coaches are continually trying to foil their opponents, by doing the unexpected. In this presentation, we explore and study Pitchfx-like and Hitfx-like data using techniques and software tools that focus upon the context in which events occurred.
Greg Rybarczyk- Baseball F/X: Architecture for the Ultimate Virtual Gamecast
The ongoing evolution of the structure of the perfect baseball virtual gamecast, with its 3 key components: PitchFX, HitFX and FieldFX. Greg Rybarczyk will describe the interrelation between these three components, and identify important additional parameters to be captured and analyzed.
Marv White- PITCHfx, HITfx, FIELDfx – BASEBALLfx
Experiments are well along to track all the players and the ball in play. With all that working, we will have a Digital Record of the Event (DRE). Very promising ideas are in play for HITfx. PITCHfx, HITfx and FIELDfx offer tremendous new insights into baseball and how it is played.
