save the RGB numbers of an image inside a cell

5 visualizzazioni (ultimi 30 giorni)
Hi. I would like to save the RGB numbers of an image (see RGB_value) inside a cell (see matrix) that has the same size as the image and in the same determined position.
For example: in the code below I have taken the values X=71 and Y=35 to which correspond RGB_value = [244 244 244]. I should save this RGB_value inside a 'matrix' cell at position X=71 and Y=35.
I should then apply the same argument for all other RGB_values for X=1:col_imageArray and Y=1:row_imageArray.
At the moment I was only able to determine RGB_value of one pixel but I can't insert this value inside the cell at the desired position.
imageArray = importdata("ssg.jpg");
figure()
imshow(imageArray)
impixelinfo
row_imageArray = height(imageArray);
col_imageArray = width(imageArray);
matrix = {};
X = 71;
Y = 35;
RED = imageArray(Y,X,1);
GREEN = imageArray(Y,X,2);
BLUE = imageArray(Y,X,3);
RGB_value = [RED, GREEN, BLUE];
matrix = [matrix,{RGB_value}];

%Random data for example
rgb = randi(255,100,100,3,'uint8');
%Convert the data to a cell array, by breaking it into sub-arrays and
%storing accordingly
out = mat2cell(rgb,ones(1,size(rgb,1)),ones(1,size(rgb,2)),3)
out = 100×100 cell array

I know you said you want a cell but I think you really don't want a slow, inefficient, memory hogging cell array. I think you should use just a regular, fast and efficient double matrix. Frankly I'm not even sure why you think you want a matrix of all the pixel locations and their RGB values. Unless it's your homework which seems probable. Anyway, here is a full, extremely well commented demo to do that:
% Take an RGB Image and write all the pixel info to a csv file in the form [R, G, B, X, Y].
% It will have as many rows as pixels in the image, and have those 5 columns.
% Initialization steps.
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
%----------------------------------------------------------------------------------------------------------
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd; % or 'C:\wherever';
if ~isfolder(startingFolder)
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select an RGB image file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
%----------------------------------------------------------------------------------------------------------
% Read in the image.
rgbImage = imread(fullFileName);
% Display the image.
imshow(rgbImage);
% Put up statusbar to let you mouse around over it and see r, g, b, and (x, y)
impixelinfo();
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0.2, 0.2, 0.8, 0.8]);
drawnow; % Force immediate screen repaint.
% Get x and y for all pixels.
[rows, columns, numberOfColorChannels] = size(rgbImage)
if numberOfColorChannels == 1
% This is not an RGB image.
promptMessage = sprintf('This is not an RGB image\nDo you want to Continue processing as grayscale, \nMake RGB,\nor Quit processing?');
titleBarCaption = 'Continue?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Grayscale', 'Make RGB', 'Quit', 'Continue');
if contains(buttonText, 'Quit')
return;
elseif contains(buttonText, 'RGB')
% Convert to RGB.
rgbImage = cat(3, rgbImage, rgbImage, rgbImage);
[rows, columns, numberOfColorChannels] = size(rgbImage);
else
% Leave as grayscale.
end
end
%----------------------------------------------------------------------------------------------------------
% Get all the x and y values.
[x, y] = meshgrid(1:columns, 1:rows);
