We propose to date and analyze the financial cycle using the Maximum Overlap Discrete Wavelet Transform (MODWT). Our presentation points out limitations of the methods derived from the classical business cycle literature, while stressing their connection with wavelet analysis. The fundamental time-frequency uncertainty principle imposes replacing point estimates of turning points by interval estimates,...
Axial skeletons are promising intermediate representations of shape which are used in machine vision and higher level theories of vision to provide a concise and intuitive description of the shape. More recently, physiological correlates of axial skeletons have been reported. We show that a stable approximation of the medial axis can be generated based on an existing neurally plausible model of perceptual...
