An ICTM-RMSAV Framework for Bias-Field Aware Image Segmentation under Poisson and Multiplicative Noise

The recent publication of 'An ICTM-RMSAV Framework for Bias-Field Aware Image Segmentation under Poisson and Multiplicative Noise' on arXiv highlights advancements in image segmentation, a critical task in image processing. Traditional methods often falter when faced with noise and intensity variations, but this new model incorporates an iterative-convolution thresholding method (ICTM) and a relaxed modified scalar auxiliary variable (RMSAV) scheme to enhance performance. By utilizing a denoising component that includes an I-divergence term and an adaptive total-variation regularizer, the model effectively manages Gamma-distributed multiplicative noise and Poisson noise. Its innovative approach to estimating a smoothly varying bias field further improves segmentation accuracy. Extensive experiments validate the model's effectiveness, showcasing its superior accuracy and robustness compared to competing approaches, which is crucial for various applications in fields such as medical imag…
