How to create Image/ multiple image from raw data in MATLAB

6 views (last 30 days)
Hello everyone, I hope you are doing well. I have the dataset of shape 1x77564 .
I have write the following code which take first 1000 samples and convert it into image. but when i convert it into first 1000 some values not included in the image.
How can I create image which include all the values of 1x77564 in 1x1000 sample shape. Or How can i create mutliple image in single for loop
[row, column] = size(incomingdata);
for eachrow=1:row
if column==1000
outputdataset(eachrow,:)=incomingdata(eachrow,:);
else
targetsize = 1000;
sizeofincomingdata = column;
nrep = targetsize / sizeofincomingdata;
fullrep = floor(nrep);
leftover = targetsize - fullrep * sizeofincomingdata;
outputdataset(eachrow,:)=[repmat(incomingdata(eachrow,:), 1, fullrep), incomingdata(1:leftover)];
% outputdataset(eachrow,:)= dataset;
end
end
% dataDirectory = fullfile('C:\Users\DELL\Documents\MATLAB\Examples\R2021b\phased\ModClassificationOfRadarAndCommSignalsExample\NewDataset\DatasetGeneration\IncomingDataset');
% disp("Data file directory is " + dataDirectory);
%% create grayscale shapes that resemble the data
[numImages, lenImage] = size( outputdataset);
imSz = 1000; % assuming images are 1000x1000
imbg = false(10000,1000); % background "color"
imfg = ~imbg(1,1); % forground "color"
imSizeOut=[10000 1000]; % ImageSize
for k= 1:numImages
imData = round( outputdataset(k,:)); % get pattern
[~,Y] = meshgrid(1:1000,1:10000); % make a grid
% black and white image
BW = imbg;
BW(Y==imData)=imfg;
valueestimation=imbinarize(imresize(uint8(BW),imSizeOut));
% convert to uint8 (0 255)
valueestimationimage = im2uint8(valueestimation);
% resize (from 1000x1000)
SE=strel('disk',2);
BW=imdilate(BW,SE);
BW=imbinarize(imresize(uint8(BW),imSizeOut));
% convert to uint8 (0 255)
imoriginalestimate = im2uint8(BW);
imoriginal = flipud(imoriginalestimate);

@Image Analyst Is there is any other method in which I get the same unique pattern in 1x1000 shape?
