matlab: image search image in google

I am using matlab to create mosaic image.

To do this, I would like to use the Google image search instead of self-create my own image database.

The procedure will be:

1.get a image and divided it into small box.

2. for each box, using image search image to get a similar image and download to matlab

3.combine every downloaded image to from the mosaic image.

I have try to search the internet by most of the result are only "words to image", instead of "image to image",

will there be any example or other keys word for me to complete the step 2?
