A Wavelet-Based Algorithm for the Spatial Analysis of Poisson Data

  title={A Wavelet-Based Algorithm for the Spatial Analysis of Poisson Data},
  author={Peter E. Freeman and Vinay Kashyap and Robert Rosner and Donald Q. Lamb},
Wavelets are scaleable, oscillatory functions that deviate from zero only within a limited spatial regime and have average value zero, and thus may be used to simultaneously characterize the shape, location, and strength of astronomical sources. But in addition to their use as source characterizers, wavelet functions are rapidly gaining currency within the source detection field. Wavelet-based source detection involves the correlation of scaled wavelet functions with binned, two-dimensional… CONTINUE READING
