I already found a positive and working solution on my own, i used ginput, an inbuilt function to point any number of feature points manually and then i used KLT algorithm for the purpose of tracking
how to assign manual control points and track it in a video?

I would like to know if there exist any function in matlab to select one or more feature points manually in the first frame and track the points in the consecutive frames and processes it to acquire information regarding the changes.

Thanks for your Ginput idea. Here is a code to manually track points in video based on it --
%
%read & display multiple images from a folder
srcFiles = dir('*.tif'); % the folder in which our images exist
dist=[];
TF=0;
x_v=[];
y_v=[];
%display file order
for i = 1 : length(srcFiles)
strcat('\',srcFiles(i).name)
end
%manually track points
for i = 1 : length(srcFiles)
filename = strcat('\',srcFiles(i).name);
I = imread(filename);
imshow(I)
for j=1:size(x_v,2)
hold on;
plot(x_v(:,j),y_v(:,j),'+-', 'MarkerSize', 10);
end
hold on
[x,y]=ginput
x_v(i,:)=x;
y_v(i,:)=y;
close all
end
