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 ...

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 ...

The FFT/IFFT/DCT engine is an application specific instruction set processor (ASIP) optimized for the implementation of Fourier and cosine transforms, while also supporting general FIR equations. ...

The spatial structure includes a Frequency Domain Channel Enhancement module, which utilizes the Discrete Cosine Transform to convert grouped skeleton data into frequency domain and refines it with ...
