How you will calculate inter-ridge width of a ridges in fingerprint?

To calculate the inter-ridge width of ridges in a fingerprint, you need to measure the distance between the centers of two adjacent ridges. This can be done using a microscope or a high-resolution scanner to analyze the fingerprint. Using image analysis software, you can identify the ridge patterns and measure the distances between them accurately. The average of multiple measurements can provide a reliable estimate of the inter-ridge width.
