We generally don't read papers and explain them to people, nor read papers, convert them to code and hand over the code to people. That's way too much work to ask us volunteers to do for you. There are consultants you can hire (pay) to do that work for you if you're interested.

warning off; clear all; close all; clc;
obj = mmreader('filename.avi');
vid = read(obj);
frames = obj.NumberOfFrames %Read the Total number of frames and displyed in command window
ST='.jpg';% u can change the extension if u want to
%%ex)readind and writing the 100 frames
%if u want to change the values means replace upto 1:776
for x = 1:100% just for 100 frames
Sx=num2str(x);
Strc=strcat(Sx,ST);
Vid=vid(:,:,:,x);
imwrite(Vid,Strc);
end
Input_seq1=imread('1.jpg');
I=rgb2gray(Input_seq1);
imshow(Input_seq1)
title('original Image')
figure,imshow(I)
title('GRAY SCALE IMAGE')
%% now perform shot boundary detection using differeent derivates/filters like sobel,prewitt or morphologcaal operators like strel commands
