Variable DCT block size #5
Description
JPEG uses 8x8 blocks. But there's no reason we can't apply DCT to bigger sizes.
It could be cool to make this changeable or just apply DCT on the whole image. Similar to the "full discrete cosine transform" figure in this article: https://parametric.press/issue-01/unraveling-the-jpeg/.
It's really interesting trying this at a full scale image and then removing most of the low frequency, so we can isolate just the high frequency bits. It leads to some really cool visualizations:
