New unsupervised method detects artefacts in histopathology images

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Artefact Prototype Learning (APL), a new unsupervised method for identifying technical artefacts in histopathology images. APL leverages the geometry of pre-trained embedding spaces to detect artefacts without requiring manual labels or fine-tuning. The approach identifies prototypes of out-of-distribution patches to differentiate artefact patterns from tissue, showing promise in detecting issues like blur and dark spots, though it faces challenges with tissue folds and blood. AI

IMPACT This method could improve the accuracy of diagnostic tools by reducing noise from image artefacts without extensive manual annotation.

    The APL Doesn't Fall Far From The Tree: Unsupervised Artefact Prototype Learning in Histopathology

    arXiv:2611.08838v1 Announce Type: new Abstract: Histopathology foundation models provide rich representations of tissue morphology, but technical artefacts in whole slide images introduce noise that may impact diagnostic accuracy. We introduce Artefact Prototype Learning (APL), a…
