---------------------------------------------------------
Maybe you could quickly take the mean of the snapshot and adjust it
with mat2gray, imadjust, or manually if the mean is not reasonably
close to the mean of the prior fixed-up snapshot.

thanks for reply,
sir,I capture frame from video using triggered subsystem in certain time interval.when its trigger,the capture frame appear in display if you have seen for long time it produces effect on eye.so that i want to append the captured frame simultaneously like scroll the frame,please give me a solution.

I thought I did. I don't really have time to give you a full turnkey
solution. Sorry but I have a full time job. You're going to have to
do the coding for your project yourself.

thanks for reply,
I want to make vision system for surface inspection of laminated steel sheet to detect the defects which is moving in speed of 0.5 to 1 m/s .i make algorithm that tachometer trigger the camera to capture the frame(on the basis of speed) and in captured frame i applied morphological operation(top hat) to separate the defects and background,and give to edge detection which is applied to blob analysis which find the defects location.so please help to improvement in algorithm or suggest any algorithm to solve above problem.how to find the area of defects and location.
thanks in advance.

That might work. Give it a try. If you need a tutorial in blob
detection, see my BlobsDemo in my File Exchange.

thanks,
I want to generate a vector using linspace function,that have three argument a,b,n.
please give me a embedded matlab code for linspace function.so that i used it,in matlab embedded function block.

--------------------------------------------
I don't know what an embedded function block is. If that's Simulink,
I don't have Simulink. I'm not sure what your confusion about
linspace is. It's pretty simple, like
a=0;
b = 10;
n = 21;
out = linspace(a,b,n)

In a MATLAB Function Block, to use MATLAB functions that are not part of the embedded MATLAB subset you need to define them as being coder.extrinsic.

See http://www.mathworks.com/help/toolbox/coder/ref/coder.extrinsic.html for more info.
