Rotation

Crop 2D/3D images with arbitrary box size and orientation(s).

The RotCrop Plugins for ImageJ allow to perform rotated crop of 2D/3D images. In fully manual versions, the crop can be defined based on crop dimensions, crop center, and rotation angle(s) of the crop frame (in 3D, three angles are necessary).

Additional plugins provides an estimate of the rotation based on the gradient vector computed around the crop frame center. The gradient direction is used as vertical direction in the result, making it easier to generate 2D/3D images that are tangent to a surface such as the epidermis of an organ or organism.

CLIJ2 is a GPU-accelerated image processing library for ImageJ/Fiji, Icy, Matlab and Java. It comes with hundreds of operations for filtering, binarizing, labeling, measuring in images, projections, transformations and mathematical operations for images. While most of these are classical image processing operations, CLIJ2 also allows performing operations on matrices potentially representing neighborhood relationships between cells and pixels.

CLIJ2 was developed to process images from fluorescence microscopy data of developing cells, tissues, organoids and organisms.

The 3D Rotation plug-in allows you to record a 360 degree rotation of the current focused 3D VTK viewer about the vertical screen axis.

The 'angle step' parameter indicates the deviation in degrees between two consecutive snapshots. Increasing the angle will increase rotation speed (up to a point where it might look like jumping more than rotating) and reduce the final movie length.
