Wavelet atom and corresponding weighting function used for estimating the local distribution wavelet transform of a circular spot image. From left to right : the image of a circular spot, its wavelet atom at the appropriate scale and its corresponding weighting function on the top row;and their radial profile on the bottom row (red dashed lines delineate the radius of the spot)
