LSDM (MSc Thesis)

Fast and precise lung CT image generation via diffusion models

My MSc thesis introduces the Latent Semantic Diffusion Model (LSDM) for fast and precise lung CT image generation from sketches. [Thesis]

Overview of the Latent Semantic Diffusion Model (LSDM).
Overview of the proposed LSDM.
Lung CT generation compared with SPADE; note the detail at the lobe boundaries.
Generation comparison against the popular SPADE model — note the detail at the lobe boundaries.

A proposed inpainting classifier guidance makes the synthesis controllable: the guidance scale tunes the malignancy of the generated CT scans.
