Auto-correlation Wavelets Utilities

AutocorrelationShell.jl contains functions that can be used for adding gaussian noise, computing signal to noise ratio, computing structural similarity index(SSIM), performing thresholding, visualizing matrix heat map, visualizing the decomposition of the 1D transform, or calculate the entropy of a vector.

Missing docstring for wiggle(wav; taxis=1:size(wav,1), zaxis=1:size(wav,2), sc=1, EdgeColor=:black, FaceColor=:black, Overlap=true, Orient=:across, ZDir=:normal). Check Documenter's build log for details.

AutocorrelationShell.ACPlots.wiggle! — Method
wiggle!(wav; taxis=1:size(wav,1), zaxis=1:size(wav,2), sc=1, EdgeColor=:black, FaceColor=:black, Orient=:across, Overlap=true, ZDir=:normal)

Plot a set of shaded wiggles on the current displayed graphics

Arguments

  • wav::Array: matrix of waveform columns.
  • taxis::Array=1:size(wav,1): time axis vector
  • zaxis::Array=1:size(wav,2): space axis vector
  • sc::Float=1: scale factor/magnification.
  • EdgeColor::Symbol=:black: Sets edge of wiggles color.
  • FaceColor::Symbol=:black: Sets shading color of wiggles.
  • Overlap::bool=true: How signals are scaled. true - Signals overlap (default); false - Signals are scaled so they do not overlap.
  • Orient::Symbol=:across: Controls orientation of wiggles. :across - from left to right :down - from top to down
  • ZDir::Symbol=:normal: Direction of space axis. :normal - First signal at bottom (default) :reverse - First signal at top.
