Pyramid Directional Filter Banks
Okay kiddo, let's talk about pyramid directional filter banks.
Imagine you have a big pile of colored blocks. You want to organize them by color, but you also want to see how they are arranged in different directions. So you start by dividing them into two groups based on their colors, like blue and green.
But then you realize that the blue blocks are not all facing the same way. Some are pointing up, some to the left, and some to the right. So you divide them again into smaller groups based on their directions.
At the end, you have several small piles of blue blocks, each facing a different way. This is like a pyramid directional filter bank, where the blocks are signals and the colors are frequencies. The filter bank breaks down the signal into different frequency ranges and then separates them further based on their directional information.
This can be helpful for things like image and audio processing, where we want to analyze signals in different directions and frequencies. It's like looking at a picture under a microscope and seeing all the different details.
Hope that makes sense, little one!
