hello i am a beginner in matlab. i have 10 frames of echocardiography so each frame is in a time index.(t1,t3,t5...) i want to interpolate between these images in time domain to make 10 frame to 20 frames to increase the frame rate. could anyone help me. its possible to use interp1 for each pixel, how cani do it? thanks

m = 100; n = 100 ;
I = rand(m,n,10) ; % your frames
fr = 1:2:20 ; % frame time
fri = 2:2:20 ; % frame time to be inteprolated
Ii = zeros(m,n,length(fri)) ; % initiliaze the interpolated frames
%%inteproaltion
for i =1:m
for j = 1:n
I_ij = squeeze(I(i,j,:)) ;
Ii_ij = interp1(fr,I_ij,fri,'spline') ;
Ii(i,j,:) = reshape(Ii_ij,1,1,length(fri)) ;
end
end
You can vectorize the above one.

hello sir thanks for your attention could you please tell me what are m and n? and what does rand do here?

m, n are dimensions....rand, I created a random matrix to replicate the frames.
