I've never heard of the umbral. But to find the half way point in between the two peaks, first find the peaks, using findpeaks() if you have the Signal Processing Toolbox, or with thresholding and regionprops() if you have the Image Processing Toolbox. Then just take the average of the two locations.

Do you have the Signal or Image processing Toolboxes? Please attach your code and data here with the paper clip icon.
