[iarectangle] [Up] [iacrop] Image Information and Manipulation

iaroi
Cut a rectangle out of an image.

Synopsis

g = iaroi( f, p1, p2 )

Implemented in Python.

Input

f	Image. Gray-scale (uint8 or uint16) or binary image (logical). input image.
p1	Image. Gray-scale (uint8 or uint16) or binary image (logical). indices of the coordinates at top-left.
p2	Image. Gray-scale (uint8 or uint16) or binary image (logical). indices of the coordinates at bottom-right.

Output

g	Image. Gray-scale (uint8 or uint16) or binary image (logical).

Examples

>>> f = iaread('lenina.pgm')

>>> iashow(f)

(256, 256) Min= 36 Max= 255 Mean=88.958 Std=46.38

>>> froi = iaroi(f, [90,70], [200,180])

>>> iashow(froi)

(111, 111) Min= 45 Max= 209 Mean=112.001 Std=29.94
