MATLAB: Error in loading image

imageimread

Hi,

I've used the syntax :

A=imread('Image1.jpg'); imshow(A)

I get the error:

??? Undefined function or method 'Image' for input arguments of type 'char'.

(I'm working in the same directory of the image file)

Best Answer

Thank you both for suggestions.

I've used 'image' inside my program name. The 'image' displayed in the error was referring to it.

The error has disappeared by renaming the program.

Thank you for help

MATLAB: How to change set of image names into directory

numImages is not the number of images in that folder, it's the length of the imageNames cell array. Though it's not really a cell array, it's just a single cell with the string holding the folder in the one and only cell. So the length is 1 cell, and numImages is 1. Please read the FAQ on cells and you will understand: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

So, assuming you fix that, you didn't give your error message. I don't see anything in your code where you tried to open a database. Please GIVE ALL THE RED TEXT . Don't snip or paraphrase like you did. We want it all, line numbers, traceback, code statements, everything .

MATLAB: 3-D image matrix made from 2-D MRI images

You are replacing the value of Img inside the for loop. The matrix is rewritten at the next iteration. Try this

clc; clear all; close all;
[Name, Path] = uigetfile('*.*',  'All Files (*.*)','MultiSelect','on');
if ~iscell(Name)  
    Name = {Name};
end
%% matrix
for i = 1:1:length(Name)
    Nazev = Name(1,i);
    Nazev = char(Nazev);
    Img_info = [Path Nazev];
    Img = imread(Img_info);
    Img_matrix(:,:,i) = rgb2gray(Img);
end
montage(Img_matrix)
