imaqmontage
Sequence of image frames as montage
Syntax
imaqmontage(frames)
imaqmontage(obj)
imaqmontage(...,CLIM)
imaqmontage(..., 'CLim', CLIM, 'Parent', PARENT)
h = imaqmontage(...)
Description
imaqmontage(frames)
显示一个蒙太奇在MATLAB的图像帧®figure window using theimagesc
function.
frames
can be any data set returned bygetdata
,peekdata
, orgetsnapshot
.
imaqmontage(obj)
calls thegetsnapshot
function on video input objectobj
and displays a single image frame in a MATLAB figure window using theimagesc
function.obj
must be a 1-by-1 video input object.
imaqmontage(...,CLIM)
displays a montage of image frames, whereCLIM
is a two-element vector,[CLOW CHIGH]
, specifying the image scaling. UseCLIM
to specify a scaling value when overscaling the image data is a risk, for example, when you are working with devices that provide data in a 12-bit format.
imaqmontage(..., 'CLim', CLIM, 'Parent', PARENT)
whereCLIM
is as noted previously, andPARENT
is a valid AXES object that allows you to specify where the montage is displayed. One or both property/value pairs can be specified. See the example below.
h = imaqmontage(...)
returns a handle to an image object.
Note
To get a list of options you can use on a function, press theTabkey after entering a function on the MATLAB command line. The list expands, and you can scroll to choose a property or value. For information about using this advanced tab completion feature, seeUsing Tab Completion for Functions.
Examples
Construct a video input object associated with a Matrox®device at ID 1.
obj = videoinput('matrox', 1);
Initiate an acquisition and access the logged data.
start(obj); data = getdata(obj);
Create an axes object.
a = axes;
Display each image frame acquired on axesa
.
imaqmontage(data, 'Parent', a);
Remove the video input object from memory.
delete(obj);
