I need to crop an dental radiograph automatically such that I get only a single tooth.Can anyone help me in writing a code for this?

[Jason Moore]

Using the following code should read the image in, crop it, show it, and then write it to a new .jpg file. To automatically crop each individual tooth you will need to use recognition rules in the image processing toolbox to help single out each tooth.

myImage = imread('myImage.jpg') %imports in the data from the image file
myImage = myImage(70:140,80:130,:) % Crops the image by splitting the array
imshow(myImage) %Shows what the image will look like in MATLAB
imwrite(myImage,'myImageCrop.jpg') %Saves the image back off to a .jpg file.

There is nothing in MATLAB to that at a high level so you'd have to build something from lower level routines. This is a very difficult project, so good luck.
