Though i have a rgb image, it shows an error while executing
gray=rgb2gray(image)
this is the image

The problem is probably that you named your image ‘image’. That’s the name of a quite useful core MATLAB function you will likely want to use. (This is called ‘overshadowing’ — in this instance overshadowing the funciton name with your variable name.)
This works:
I = imread('charuleelaa vanilavarasu_1.jpeg');
gray=rgb2gray(I);
figure(1)
imshow(gray)

Do not use "image" as the name of a variable.
You do not show your code. Note that you must pass the result of imread to the function, not the file name.
