Intensity leveling and false coloring of fluorescence-based 3D histology with FalseColor-Python

Fluorescence-based slide-free digital pathology techniques, including 3D microscopy, are gaining interest as alternatives to traditional slide-based histology. Since pathologists are accustomed to the appearance of standard histology stains, the ability to render grayscale fluorescent images with color palettes that mimic traditional histology is valuable. We present FalseColor-Python, an open-source rapid digital-staining package that renders two-channel fluorescence images to mimic standard histology. Our package offers consistent color-space representations that are robust to both intra-specimen and inter-specimen variations in staining and imaging conditions, along with GPU-accelerated methods to process large datasets efficiently.
