How to use image input with Neural Network?

I'm new for neural network. I don't know how to train and test neural network with image processing. when I read image into matlab it will be matrix and I covert to gray and 2*2double matrix. If I have many image matrix to train. Should I have to concatenate every image matrix to one image matrix that will be same row but many column or Should I have to covert image matrix to one column per one image first and concatenate every column to one image matrix ?. How I have to do and what function to do that?

If you have N images of size I =row*column, each image is columnized to form a column in the input matrix with size

[I N ] =size(iput)

Hope this helps.

Thanks for answer. but I don't understand. please describe algolithm to form image for use with Neural Network in newff and train function. After I read image with this code.

I1 = imread('1.jpg');

I2 = imread('2.jpg');

I3 = imread('3.jpg');

G1 = rgb2gray(I1);

G2 = rgb2gray(I2);

G3 = rgb2gray(I2);

D1 = im2double(G1);

D2 = im2double(G2);

D3 = im2double(G3);

How can I form these image to be input data for newff ?

col = image(:);

Although, using extracted features instead of the whole image is recommended.

How to input an image and let matlab to detecet it using neural network ?

Answer 3

input = [ D1(:) D2(:) D3(:) ]

Thank you for formally accepting my answer

Sir, actually I am working on blood vessel detection of reinal image given below using the paper attached with it.But I am using neural network toolbox and I don't know what input and target values should be taken so that segmentation of the image can be done.

Greg sir, I extracted features from 90X60 binary image. it is actually a column matrix of 54 elements. but i does not have neural network code for recognition of these segmented 90X60 images. so sir please can you provide me a neural network code that can recognize only 16 characters. sir i also attach a m-file of feature extraction. Thank You.

good morning sir, Present I am working on the neural networks, I want to know how image will give as input to neural networks and how can I process it. Thank you sir

hi have you find something .i have also start with neural network

I cant seem to get my layered graph to compile into a DAG network. How did you do it? Assembly wont work as well as replacing a layer.
