I have to find location of image captured using webcam. adaptorName = 'winvideo'; deviceID = 1; vidFormat = 'RGB24_640x480'; vid = videoinput(adaptorName, deviceID, vidFormat); I = getsnapshot(vid); % fullImageFileName = fileparts(which(I));
I have to get path of image into fullImageFileName variable..

getsnapshot returns Image frame(3D-array), it doesn't write that into memory as an image. So, I is nothing but a variable in matlab workspace. See:
whos I
To write it into memory as an image for future uses:
imwrite(I , 'fullFileName')
