The new ShapeEmbed deep learning method helps quantify shapes in bioimages 🔬 It learns to encode 2D object outlines into descriptors that are invariant to several geometric transformations. Great for robust cell shape analysis, classification & exploring phenotypes.

Taking pictures of cells with a microscope, then extracting thousands of features from them is uncannily effective for quantifying cell state, esp. for genes and chemicals (e.g., Cell Painting). But we often average the rich single-cell data to simplify analysis. Can we do better?
