How to get the pixel color values in one command?

I want to get the color pixel value in one line command or syntax.

I know we have to use get below syntax Red=Image(x,y,1); Green=Image(x,y,2); Blue=(Image(x,y,3);

But it make program too long.

I have to check the color of each pixel in image. So Is there any other syntax to get the specified pixel color range in one array.

I want the output like this

= 255 242 0

Yes, the color is a vector of three values. To access the color of pixel (x,y), you can write:

color = squeeze( Image(x,y,:) );

and color will be a vector of length 3.

Thanks to Walter Roberson for suggesting using squeeze.

As Image Analyst noted in the comments, you can also use the impixel function.

Yes it worked. but i din't get result as i want. I get this result

>> color=RGB(56,54,:); >> color

color(:,:,1) =

    0

color(:,:,2) =

    0

color(:,:,3) =

    0

i wanna a matrix to compare with other colors. Like, Red=[237 28 36]; yellow=[255 242 0];

So i need same as this of matrix as result.

squeeze(RGB(56,54,:))

For what it's worth, there's also an impixel() function.

disp(reshape(Image, [], 3));

i didn't understand this syntax. how it is working?
