# Function iaregmax

namespace: morph iaregmax

# Synopse

Regional Maximum.

• y = iaregmax(f, Bc=iasecross())
• y: Image
• f: Image
• Bc: Structuring Element (connectivity).
```01. from numpy import *
02. from iasecross import iasecross
03.
04. def iaregmax(f, Bc=iasecross()):
05.     from iasubm import iasubm
06.     from iahmax import iahmax
07.     from iabinary import iabinary
08.     from iaregmin import iaregmin
09.     from ianeg import ianeg
10.
11.     y = iasubm(f, iahmax(f,1,Bc))
12.     return iabinary(y)
13.     #return iaregmin( ianeg(f),Bc)```

# Description

iaregmax creates a binary image y by computing the regional maxima of f, according to the connectivity defined by the structuring element Bc. A regional maximum is a flat zone not surrounded by flat zones of higher gray values.

# Examples

## Example 1

```01. from ia870 import iaregmax
02. from ia870 import iasecross
03.
04.
05. a = array([
06.     [10, 255, 255,  10,  10,  10,  10],
07.     [10,   9,   6,  18,   6,  15,  10],
08.     [10,   9,   6,  18,   6,  15,  10],
09.     [10,   9,   9,  15,   0,   9,  10],
10.     [10,   9,   9,  15,  12,  10,  10],
11.     [10,  10,  10,  10,  10,  10,  10]],uint8)
12.
13. print iaregmax(a) * 1```
