Statistical Inference of RFID Tag Positions: Inferring the Tag's Position (1st Run)

A video showing part of the results for my Undergraduate Thesis at UOIT. This thesis focused on an approach to statistically inferring the position of an RFID tag given a number of observations from RFID receivers at varying power levels and also given a set of calibration data for well defined points in the room.

This video visualizes statistical likelihood of a the Tag E existing at every defined point in the room given a set of recorded observations. The hotter the colour the greater the statistical likelihood. In this case after approximately 1000 observations the likelihood focuses to an area around a single point. The actual location of the Tag is approximately 1 meter away from the inferred position. See http://william.howard.name/research for the full text of the thesis.
