HE-NAC: High-Efficiency Neural Audio Coding via Hierarchical and Residual Multi-Band Quantization

Darius Pétermann, Wootaek Lim, Seungkwon Beack +1

High-fidelity audio coding requires faithful reconstruction of perceptually important high-frequency components, which are often lost due to the aggressive temporal decimation and…

Need for objective task-based evaluation of AI-based segmentation methods for quantitative PET

Ziping Liu, Joyce C. Mhlanga, Barry A. Siegel +1

Artificial intelligence (AI)-based methods are showing substantial promise in segmenting oncologic positron emission tomography (PET) images. For clinical translation of these meth…

No-gold-standard evaluation of quantitative imaging methods in the presence of correlated noise

Ziping Liu, Zekun Li, Joyce C. Mhlanga +2

Objective evaluation of quantitative imaging (QI) methods with patient data is highly desirable, but is hindered by the lack or unreliability of an available gold standard. To addr…

Observer study-based evaluation of a stochastic and physics-based method to generate oncological PET images

Ziping Liu, Richard Laforest, Joyce Mhlanga +5

Objective evaluation of new and improved methods for PET imaging requires access to images with ground truth, as can be obtained through simulation studies. However, for these stud…

A no-gold-standard technique to objectively evaluate quantitative imaging methods using patient data: Theory

Jinxin Liu, Ziping Liu, Joyce Mhlanga +2

Objective evaluation of quantitative imaging (QI) methods using measurements directly obtained from patient images is highly desirable but hindered by the non-availability of gold…

A Bayesian approach to tissue-fraction estimation for oncological PET segmentation

Ziping Liu, Joyce C. Mhlanga, Richard Laforest +3

Tumor segmentation in oncological PET is challenging, a major reason being the partial-volume effects that arise due to low system resolution and finite voxel size. The latter resu…
