clij - GPU-acceleration for ImageJ


clij is an ImageJ/Fiji plugin allowing you to run GPU-accelerated code from within Fijis script editor (e.g. macro and jython). CLIJ is based on ClearCLImglib2 and SciJava. It contains components for image filtering, thresholding, spatial transforms, projections, binary image processing and basic signal measurements.

ImageJ Auto Crop


This plugin can find the smallest bounding box of an image (or a rectangular part defined by a selection) by cropping as much background as possible. Found in Fiji, under Image> Adjust.

In the version labeled with (guess background color), the plugin tries to determine the background color by looking at the pixels on the border of the image, while Auto Crop uses the currently selected background color which can be changed by double-clicking on the pipette symbol or using the Image > Color > Color Picker....

Instead of cropping right away, you can set the selection to the rectangle that would be cropped to using Edit > Selection > Select Bounding Box.
