Find extended maxima
I=[1 1 1 1 1;1 5 1 4 1;1 1 1 1 1];
BW=imextendedmax(I,2);
figure; subplot(1,2,1); imagesc(I); title('Image');
subplot(1,2,2); imagesc(BW); title('Extended maxima');
BW = imextendedmax(I, h)
BW = imextendedmax(I, h, conn)
| Parameter | Description |
|---|---|
| I | Input finite real 2-D image. |
| h | Nonnegative finite height for the h-maxima transform. |
| conn | Connectivity, either 4, 8, or an equivalent 3-by-3 matrix. |
| Parameter | Description |
|---|---|
| BW | Logical mask of regional maxima after h-maxima suppression. |
imextendedmax applies imhmax and then finds regional maxima. It helps build marker masks that ignore maxima shallower than h.
