What this part means

the height.

Its job in the formula

H is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

for an image of height H and width W at patch size P .

The passage around this formula

for an image of height H and width W at patch size P . The quadratic relationship is the entire practical story of image tokenisation. Halving the patch size quadruples the sequence, and attention cost grows faster still. Every deployed system therefore resolves a three-way tension between input resolution, patch size, and context budget, and it resolves it by throwing away detail.
