Fig 2. Graphical depiction of image analysis workflow for selected images with different shape embryos and a range of different background colours and textures.
Images show that embryo detection and stain colour analysis is effective independently of a wide range of variation in image background and embryo characteristics. All images were analysed without changing initial parameters. Note image (d) where even the human eye struggles to distinguish the upper border of the embryo from the background.

Fig 5. Developmental progression of expression for selected genes prdm1, ank1, and hoxb3 during Xenopus embryo development.
This is the result of applying our suite of image analysis tools to (in this case) the 334 original images for these three genes, and reducing them to a representative set of 65 images, including multiple views of expression patterns from the early spherical stages (pre-Stage 22).
