Convert an image to a matrix and convert to gry scale?

Hello to everyone.

I'm new of Matlab. Currently I'm working with version 2011.

My question is rather simple: I've a function taking as parameter "imagen"(which is name+extension of a RGB (colored) image).

I load the image: img1 = imread(imagen,jpeg)

Now I want do the following:

1) Convert the image to a matrix

2) Show the image

3) Convert the original image to gray scale

4) Show the new image

I looked at reference but I'm a bit confused.

Any suggestion is really appreciated. I just suppose it something like "plot"..but that's all what I understood.

Thank you in advance

hi,

It is so simple. Probably you should refer to the technical support documentations online.

Btw the simple answers are as follows :-

a) As you imread into img1, the image is converted into a matrix and stored into img1.

b) to show the image use imshow(img1);

c) convert to grayscale by img2 = rgb2gray(img1);

d) again show the image by imshow(img2);

Hope this helps

happy to help

I will try it later but it's very clear. Thank you!
