Double precision wavelet transform

Hi,

I'd like to know if it was possible to use the wavelet transform in double precision (64bits).

Thanks

Thomas

Hello,

Thanks for your question. Wavelet transform function support 16s, 32f and 64. You can refer this document for more detail information.

Thanks,

Hello,

Sorry my question was not very precise, I was talking about a 2D wavelet transform, for images.

In the documentation it is only mentioned 32bits but I wonder what would happen if my inputs are of double precision.

Thanks

Thomas

Hello Thomas,

Right. for 2D wavelet transform, it only supports 32f so far. I will file it as feature request for future review.

Thanks,

Alice

Thanks! That would be really
