Heatmap of pixel-wise F1 score of conditional random field (CRF) segmentation across different levels of θα, corresponding to the spatial scale of correlations between pixel color values, and θβ, corresponding to the color space scale of correlations. Values were determined using images transformed with red, green, and blue values transformed via linear discriminant analysis-derived differentiation transformation, as this was the color space in which CRF segmentation performed best.
