ICASSP Sequences
Both sequences have infrared and visible spectrum data associated with them. The face tracking sequence is shown in the visible spectrum only. The person tracking sequence is shown in thermal infrared only. These tracking sequences were used for experiments as part of: An improved spatiogram similarity measure for robust object localisation C. Ó Conaire, N. E. O'Connor, A. F. Smeaton submitted to ICASSP 2007 Abstract: Spatiograms were introduced as a generalisation of the commonly used histogram, providing the flexibility of adding spatial context information to the feature distribution information of a histogram. The originally proposed spatiogram comparison measure has significant disadvantages that we detail here. We propose an improved measure based on deriving the Bhattacharya coefficient for an infinite number of spatial-feature bins. Its advantages over the previous measure and over histogram-based matching are demonstrated in object tracking scenarios. view PDF version |
