The cells, a numpy array, became an Img, an ImgLib2 image type without metadata. In the next cell, we will open an image as a NumPy array using the scikit-image library. this W3Schools tutorial on NumPy to learn about NumPy before proceeding. This PyImageJ tutorial assumes you are somewhat familiar with NumPy already if not, please see e.g. In many cases, you will have image data in Python already as a NumPy array, or perhaps as an xarray, and want to send it into Java for processing with ImageJ routines.

💡 You can save your data with ij.io().save(image, filepath) to save your image data to disk.Ħ.7 Passing image data from Python to Java  NumPy images use where row and col correspond to Y and X respectively. ImageJ images use dimension labels and order. Note the difference in shape and dimension order between the ImageJ and xarray images. The image is 4-dimensional, 250 × 250, 3 channels, and 15 time points. uint16) with integer values in the range. what kind of sample values it has) is UnsignedShortType, the ImgLib2 class for unsigned 16-bit integer data (i.e. Notably, this class implements the interface, the primary image data type of ImageJ2. Let’s first take a look at the test_timeseries.tif image data and get important image information such as dimension and shape: Late viral gene expression / viral particle formation This reporter virus is designed to express two flourscent proteins upon viral gene expression. The sample data test_timeseries.tif is a 4D (X, Y, Channel, Time) dataset of a HeLa cell infected with a modified HIV-1 fluorescent reporter virus.
