Developed a cutting-edge hierarchical Transformer-based model for intraoperative abdominal organ segmentation, setting a new benchmark for accuracy on the Dresden Surgical Anatomy Dataset. By designing a multi-scale cross-attention decoder with a DINOv2 backbone and a hybrid loss function, I boosted Dice scores by up to 27% on challenging organ classes, such as the pancreas and colon. Additionally, I implemented an advanced ROI extraction strategy to enhance the segmentation of smaller and partially cropped organs, significantly improving the model's performance on complex, structurally intricate regions.

Researching on a modified Diffusion-based Near-Infrared (NIR) model for colorizing night vision footage, incorporating ILVR-style refinement for improved output. The model was tested on the NIR2RGB VCIP dataset, where it achieved strong results, including a Peak Signal-to-Noise Ratio (PSNR) of 22.7 dB and a Structural Similarity Index (SSIM) of 0.67. These results demonstrated significant perceptual improvements in color fidelity and detail reconstruction, outperforming baseline GAN and U-Net approaches in terms of both accuracy and visual quality.
