With $I$ as the intensity in grayscale at the point with coordinates (x,y). The points of interest retained are those where the DoH exceeds a threshold $H$. The threshold value is automatically calculated to reach the desired number of points. We classify the number of points into three ranges:
Low point density: Number of points $\in \lbrack 300\ ;500\rbrack$
Medium point density: Number of points $\in \lbrack 1000\ ;2000\rbrack$
High point density: Number of points $\in \lbrack 3000\ ;6000\rbrack$
* Low point density: Number of points $\in \lbrack 300\ ;500\rbrack$
* Medium point density: Number of points $\in \lbrack 1000\ ;2000\rbrack$
* High point density: Number of points $\in \lbrack 3000\ ;6000\rbrack$
To ensure that stabilization is performed on the banks, the user defines a "flow" area in which no points of interest will be extracted.
