PROGRAM NAME
vthreshm - Adaptive Thresholding of an Image
DESCRIPTION
vthreshm
will do the adaptative threshold of an input image. Two input images can be entered as the lower and higher limit images. Optionally, two integer parameters can be entered instead of these images.
The three input images must be of the same size and have the same
number of data bands.
REQUIRED ARGUMENTS
- -i1
-
type: infile
desc: Image to be compared
- -o
-
type: outfile
desc: resulting output image
Mutually Exclusive Group; you must specify ONE of:
- -i2
-
type: infile
desc: Lower threshold level
default: {none}
OR
- -l
-
type: integer
desc: lower thresh. level
default: 128
bounds: -32768 < [-l] < 32767
Mutually Exclusive Group; you must specify ONE of:
- -i3
-
type: infile
desc: Upper thres. level
default: {none}
OR
- -u
-
type: integer
desc: upper thresh. level
default: 255
bounds: -32768 < [-u] < 32767
OPTIONAL ARGUMENTS
none
EXAMPLES
vthreshm -i1 img1.xv -i2 img2.xv -i3 img3.xv -i4 img4.xv -o img5.xv
img1 is the image to be compared
img2 is the lower limit image
img3 is the higher limit image
img4 is the result of the comparition
SEE ALSO
RESTRICTIONS
vthreshm is presently only implemented for byte images. The input images' data type can be BYTE or SHORT. The resulting image will be of the BYTE data type.
