A facility implementing systems and/or methods for creating statistically significant signatures for targets of interest and using those signatures to identify and locate targets of interest within image data, such as an array of pixels, captured still images, video data, etc., is described. Embodiments of the facility generate statistically significant signatures based at least in part on series approximations (e.g., Fourier Series, Gram-Charlier Series) of image data. The disclosed techniques allow for a high degree of confidence in identifying and tracking targets of interest within visual data and are highly tolerant of translation and rotation in identifying objects using the statistically significant signatures. |
