Figure 1. Attention visualization at selected query points. We
show an input resized to 512 × 512 using the CLIP ViT-B/16 vi-
sion encoder. For each colored query, we compare the attention
maps produced by CLIP [51], NACLIP [26], and our PEARL.
CLIP exhibits diffuse and background-biased responses, while
NACLIP improves localization but often fragments objects into
isolated peaks. By performing Procrustes alignment in the last
self-attention block, PEARL yields compact and object-consistent
attention, suppresses background spill, and better preserves thin
parts, resulting in stable focus with reduced grid artifacts.
