This plugin copies the pixel size from the calibration of one image or stack to a second image or stack. This allows one to copy the spatial calibration from one stack to another.
A second dialog allows to enter the scale factors.
This plugin extracts groups of connected pixels in 2D and 3D based on their intensity and that of the background. Works on both binary and gray-scale data. Output can be pushed to the swimming pool for other plug-ins to further exploit the extracted objects.
