how to Initialize the starting point for region growth.

how to Initialize the starting point for region growth.

Using the [x,y] coordinates entered by the user, initialize the image

so that only the point (x,y) is at “1” and the rest of the image is at “0”.

knowing that the x coordinate indicates the column number and the coordinate

y indicates the line number in the image.

"only the point (x,y) is at “1” and the rest of the image is at “0”. knowing that the x coordinate indicates the column number and the coordinate y indicates the line [row] number in the image."

Assuming you have gotten x and y from the user already, one way or another, then to initialize such an image, you can do this:

image_size = [100 100];
x = 30; % 30th column in image
y = 44; % 44th row in image

image_matrix = zeros(image_size); % initialize image to a matrix of all zeros of the specified size
image_matrix(y,x) = 1; % set element at row y, column x to 1

imshow(image_matrix)
