So code will be like:

Preview of how output will be:

Details of

videoinput & preview function:

"videoinput" function :

# here 'v' is the video object created after executing the "videoinput" function.

# here "Adapter_name" is a string that specifies the name of the adapter used to communicate with that particular device.





NOTE: Use the "imaqhwinfo" function to determine the adaptors available on your system. Its output will be like:

With these info., we can use 'gentl' or 'gige' or 'matrox' or 'ni' or 'winvideo' as Adapter_name.





# here Device_ID is a numeric scalar value that identifies a particular device available through the specified adaptor, Adapter_name.





NOTE: Use the "imaqhwinfo(Adapter_name)" syntax to determine the devices available through the specified adaptor. If Device_ID is not specified, the first available device ID is used. For convenience, a device's name can be used in place of the Device_ID. If multiple devices have the same name, the first available device is used.

NOTE:

SAMPLE OUTPUT:

Here 'YUY2_1280x1024' , 'YUY2_1280x800' , 'YUY2_160x120' , 'YUY2_176x144' ,

'YUY2_320x240' , 'YUY2_352x288' & 'YUY2_640x480' are the supported video format of the device_name 'winvideo' use that.

"preview" function

It Display preview of live video data. preview(v) creates a Video Preview window that displays live video data for video input object 'v'. The window also displays the timestamp & video resolution of each frame, and the current status of 'v'. The Video Preview window displays the video data at 100% magnification (1:1).





It is actually possible to access various hardware, with MATLAB codes. One of the hardware is your Webcam, in order to take a video or a Picture as an input.The functions we are going to use for it is: "" & "This "" function creates a "video input object" which can be used for previewing the video through "" function.%start of code%end of code Click here to see Click here to see# FORMAT is a text string that specifies a particular video format supported by the deviceTo get a list of the formats supported by a particular device, view thestructure for the device that is returned by thefunction.
