digital image processing-Geophysical wavelet library
In the present paper, we consider and summarize applications of the continuous wavelet transform to 2C and 3C polarization analysis and filtering, modeling the dispersed and attenuated wave propagation in the time–frequency domain, and estimation of the phase and group velocity and the attenuation from a seismogram. Along with a mathematical overview of each of […]
Fundamentals of Image Processing-free book-2
Sampling: Continuous to Discrete (and back) It is often more convenient to process a continuous-time signal with a discrete-time system. Such a system may consist of three distinct stages: (1) the conversion of a continuous-time signal to a discrete-time signal (C/D converter); (2) the processing through a discrete-time system; and (3) the conversion of the […]
Digital Image Processing Fundamentals-free book
Digital image processing is electronic data processing on a 2-D array of numbers. The array is a numeric representation of an image. A real image is formed on a sensor when an energy emission strikes the sensor with sufficient intensity to create a sensor output. The energy emission can have numerous possible sources (e.g., acoustic, […]
