Please copy all the red error text - don't just snip out some of it. I'm not seeing line number, the actual line of code, etc.

Unable to allocate memory for an incoming image frame. Use IMAQMEM to modify the frame
memory limit.
Error in imaqdevice/getsnapshot (line 60)
snapshot = getsnapshot(imaqgate('privateGetField', obj, 'uddobject'));
Error in RedObjectTracking (line 27)
data=getsnapshot(vid); %We declare a variable 'data' to store the

Note: if the error message had instead been the slightly different
Unable to allocate memory for an incoming image frame due to insufficient free physical memory.
and you are using OS-X or MacOS, then see https://www.mathworks.com/support/bugreports/1422542

Ayesha,
On all platforms, use this before running any functionality from the Image Acquisition Toolbox to not limit memory for MATLAB:
imaqreset
imaqmex('feature','-limitPhysicalMemoryUsage',false);
% create videoinput objects

Hi, I have the same problem (using Matlab R2014a , macvideo and OS X Yosemite). When I write imaqmex('feature','-limitPhysicalMemoryUsage',false); I have the following error: Error using imaqmex The IMAQMEX feature specified is invalid. Would you know why?
