Abstract:

 

The goal of this thesis is to develop a set of tools for continuous

tracking of behavioral phenomena in videos to support human behavior

study. Current standard practices for extracting useful behavioral

information from a video are typically difficult to replicate and

require a lot of human time. For example, extensive training is

typically required for a human coder to reliably code a particular

behavior/interaction. Also, manual coding typically takes a lot more

time than the actual length of the video. The time intensive nature of

this process puts a strong limitation on the scalability of the study.

Furthermore, this makes it difficult for a third party to perform

replication study.

 

To address this issue, I have developed an efficient interactive

tracking and behavior retrieval system. These tools allow behavioral

researchers/clinicians to more easily extract relevant behavioral

information, and more objectively analyze behavioral data from videos. I

have demonstrated that my behavior retrieval system achieve

state-of-the-art performance in a preliminary experiment. In the

proposed work, I will perform a more thorough evaluation of this system

on a wider set of behaviors. I have also demonstrated that my

interactive tracking system is able to produce high-precision tracking

results with less human effort compared to the state-of-the-art. In the

proposed work, I will show how a proximity measure that is derived from

the results of interactive tracking can be used to predict attachment

classification in The Strange Situation, a protocol for studying infant

attachment security. In addition, I will also show how this measure

opens a new avenue of behavioral research by showing that it can be used

to quantify the consistency of infant behavior in the two reunion

episodes in Strange Situation.
