skimage2.data.cell()[source]#

Cell floating in saline.

This is a quantitative phase image retrieved from a digital hologram using the Python library qpformat. The image shows a cell with high phase value, above the background phase.

Because of a banding pattern artifact in the background, this image is a good test of thresholding algorithms. The pixel spacing is 0.107 µm.

These data were part of a comparison between several refractive index retrieval techniques for spherical objects as part of [1].

This image is CC0, dedicated to the public domain. You may copy, modify, or distribute it without asking permission.

Returns:

cellndarray of shape (660, 550) and dtype uint8: Image of a cell.
