conv2 not found #27

Open SimonRuetz opened 2 years ago

SimonRuetz commented 2 years ago

The command cov2 is no longer implemented in julia. conv has been moved to the package DSP.jl if I'm not mistaken. After installing Shearlab directly from github (on Julia 1.8 beta) the following code doesn't work

Im #Some image
using Shearlab
nScales = 4;
shearLevels = ceil.((1:nScales)/2)
scalingFilter = Shearlab.filt_gen("scaling_shearlet");
directionalFilter = Shearlab.filt_gen("directional_shearlet");
waveletFilter = Shearlab.mirror(scalingFilter);
scalingFilter2 = scalingFilter;
full = 0;
scales = 4;
@time shearletSystem_nopar = Shearlab.getshearletsystem2D(size(Im,1), size(Im,2), scales,shearLevels,full,directionalFilter,scalingFilter,0);

This leads to the following error:

ERROR: LoadError: UndefVarError: conv2 not defined
