Develop and evaluate FASL-Seg, a feature-adaptive semantic segmentation framework designed to accurately parse anatomical structures and surgical instruments in robotic minimally invasive surgery.
Constructed FASL-Seg using a SegFormer backbone augmented with High-Level Feature Projection for low-resolution maps and Low-Level Feature Projection for high-resolution features.
Integrated a shallow decoder designed to maximize information retention across diverse representations of instruments and patient anatomy.
Benchmarked segmentation performance across four surgical video datasets: EndoVis 2017, EndoVis 2018, Cholecystectomy Segmentation, and Kvasir-Instrument.
Achieved mean Intersection over Union (mIoU) scores of 0.73 on EndoVis18, 0.75 on Cholecystectomy Segmentation, and 0.74 on EndoVis17.
Demonstrated high instrument delineation accuracy with an mIoU of 0.86 on EndoVis18 tool segmentation and 0.9594 on Kvasir-Instrument binary segmentation.
