Another real-world usage of "alias" is the bash command, which creates a "false identity" for a command. For example, if you add the following line to ~/.bashrc or ~/.bash_aliases
alias la "ls -a"
The next time you open a terminal you can type "la" to see hidden files!

I find different image patch has different frequency bands and there is locality in the high frequency patch. So maybe we can represent the image more efficiently by using a quadtree where low fequency area are represented by a larger image patch while area with more high frequency details can be represented by a smaller patch. Is there any works related?
I'm also curious about the graph of turning this quadtree image into frequency domain and the physical meaning of this structure from the perspective of frequency.
