hello im a beginner in matlab. i want to increase the number of frames in a video. i have tried the interp1 but the results were not good. now i want to increase the frames in transform domain and using wavelet. my sequence has 9 frames of 512*512 pixels. so do i have to go through pixel by pixel in frames and use one dimensional dwt? for example i decompose all 9 frames to approximation and detail. and i want to produce an approximation and detail between each pixel in consecutive frames. what should i do?

clc; clear all; Image_Address_Echo_1='C:\Users\RT\Desktop\10_jpeg\'; file_format_Echo='.jpg';

for num=1:9 prefix_image='img'; Image(:,:,num)= rgb2gray(imread(strcat(Image_Address_Echo_1,prefix_image,num2str(num),file_format_Echo))); end

 m = 512; n = 512 ; %dimension of images
fr = 1:2:18 ;    % frame time
fri = 1:1:18 ;   % frame time to be inteprolated 
Ii = zeros(m,n,length(fri)) ;   % initiliaze the interpolated frames

for i=1:m for j=1:n I_ij = double(squeeze(Image(i,j,:))) ; Ii_ij = wavedec(I_ij,1,'haar');

i dont know what should be the rest
