H-minima transform

- example
`I2 = imhmin(I,h)`

`I2 = imhmin(I,h,conn)`

suppresses
all minima in the intensity image `I2`

= imhmin(`I`

,`h`

)`I`

whose depth
is less than `h`

, where `h`

is a
scalar. Regional minima are connected components of pixels with a
constant intensity value, *t*, whose external boundary
pixels all have a value greater than *t*. By default, `imhmin`

uses
8-connected neighborhoods for 2-D images, and 26-connected neighborhoods
for 3-D images. For higher dimensions, `imhmax`

uses `conndef(ndims(I),'maximal')`

.

computes
the H-minima transform, where `I2`

= imhmin(`I`

,`h`

,`conn`

)`conn`

specifies the
connectivity.

Code Generation support: Yes.

MATLAB Function Block support: Yes.
