For the filter kernel ... we multiply the two transforms to get the result at the figure’s bottom center. We can see that the 8-Hz frequency component of our input has been eliminated, and we can use ...

In this paper, we propose the parallel discrete wavelet transform as an efficient method for compressing and processing acoustic signals received at edge nodes. This approach significantly alleviates ...

Specifically, aiming at the fine-grained information of the TIR object, we employ a frequency channel attention mechanism that transforms TIR images into the frequency domain using discrete cosine ...
