Exploiting Unlabelled Photos for Stronger Fine-Grained SBIR

CVPR 2023poster

This paper advances the fine-grained sketch-based image retrieval (FG-SBIR) literature by putting forward a strong baseline that overshoots prior state-of-the art by 11%. This is not via complicated design though, but by addressing two critical issues facing the community (i) the gold standard trip…

Ideal: Improved Dense Local Contrastive Learning For Semi-Supervised Medical Image Segmentation

ICASSP 2023accepted

Due to the scarcity of labeled data, Contrastive Self-Supervised Learning (SSL) frameworks have lately shown great potential in several medical image analysis tasks. However, the existing contrastive mechanisms are sub-optimal for dense pixel-level segmentation tasks due to their inability to mine l…
