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.

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

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