- Abstract: Diffusion probabilistic model (DPM) recently becomes one of the hottest topic
in computer vision. Its image generation application such as Imagen, Latent
Diffusion Models and Stable Diffusion have shown impressive generation
capabilities, which aroused extensive discussion in the community. Many recent
studies also found it useful in many other vision tasks, like image deblurring,
super-resolution and anomaly detection. Inspired by the success of DPM, we
propose the first DPM based model toward general medical image segmentation
tasks, which we named MedSegDiff. In order to enhance the step-wise regional
attention in DPM for the medical image segmentation, we propose dynamic
conditional encoding, which establishes the state-adaptive conditions for each
sampling step. We further propose Feature Frequency Parser (FF-Parser), to
eliminate the negative effect of high-frequency noise component in this
process. We verify MedSegDiff on three medical segmentation tasks with
different image modalities, which are optic cup segmentation over fundus
images, brain tumor segmentation over MRI images and thyroid nodule
segmentation over ultrasound images. The experimental results show that
MedSegDiff outperforms state-of-the-art (SOTA) methods with considerable
performance gap, indicating the generalization and effectiveness of the
proposed model.

Deep Learning (DL) models have achieved state-of-the-art performance in diagnosing multiple diseases using reconstructed images as input.
DL models are sensitive to varying artifacts as it leads to changes in the input data distribution between the training and testing phases.
We propose to use other normalization techniques, such as Group Normalization and Layer Normalization, to inject robustness into model performance against varying image artifacts.

We propose a novel model, Multi-modal Gaussian Process Prior Variational Autoencoder (MGP-VAE), to impute one or more missing sub-modalities for a patient scan.
MGP-VAE can leverage the Gaussian Process (GP) prior on the Variational Autoencoder (VAE) to utilize the subjects/patients and sub-modalities correlations.
We show the applicability of MGP-VAE on brain tumor segmentation where either, two, or three of four sub-modalities may be missing.
