Background

This tool allows calculating the entire surface of a component in the image by thresholding the histogram.

In JMicroVision, components can be extracted as objects (e.g. particles) with the Object Extraction tool or as backgrounds (e.g. matrix) with the Background tool. The background uses less memory, can be computed faster and can be modified. For these reasons, it is recommended to extract as background when only the entire surface of a component needs to be calculated and it is not necessary to partition the background in multiple regions.

The Image Factory tool offers some image preprocessing functions and different segmentation methods for more advanced use (see tutorials on the website).

 Note: To show the real surface (if calibrated), open the Data Viewer.

 Note: For computing the background surface in a limited area (by default, the background surface percentage of the whole image is calculated), see compute result from area.
