Training-Time Optical Priors for Wireless Capsule Endoscopy Classification: Hemoglobin-Aware Input Fusion with Cross-Vendor Evaluation
Chengshuai Yang, Lei Xing, Keyaan Zawad Alam +4
Gastrointestinal cancers cause approximately 3.4 million deaths annually, and early small-bowel lesions are easily missed at wireless capsule endoscopy (WCE). RGB-trained WCE class…
Designing Any Imaging System from Natural Language: Agent-Constrained Composition over a Finite Primitive Basis
Chengshuai Yang
Designing a computational imaging system -- selecting operators, setting parameters, validating consistency -- requires weeks of specialist effort per modality, creating an experti…
InverseNet: Benchmarking Operator Mismatch and Calibration Across Compressive Imaging Modalities
Chengshuai Yang, Xin Yuan
State-of-the-art EfficientSCI loses 20.58 dB when its assumed forward operator deviates from physical reality in just eight parameters, yet no existing benchmark quantifies operato…
The Finite Primitive Basis Theorem for Computational Imaging: Formal Foundations of the OperatorGraph Representation
Chengshuai Yang
Computational imaging forward models, from coded aperture spectral cameras to MRI scanners, are traditionally implemented as monolithic, modality-specific codes. We prove that ever…
