How do you find boundaries of a binary matrix developed from an image?

5 views (last 30 days)
I currently have an image that I have put thresholds on to then create a binary matrix (833x1464). Is there any way to find the first and last row where the value 1 appears, and the same for the colums?

Yes
[rows, columns] = find(binaryMatrix);
topRow = min(rows)
bottomRow = max(rows)
leftColumn = min(columns)
rightColumn = max(columns)
