Algorithm 1

Image cropping.
(01)begin
(02)input input an image
(03)imageFiltering() //filtering noise reduction
(04) Detect all key points
(05)for (iterate through all key points)
(06)   Remove relatively isolated points
(07)   Statistics key points scope
(08)end for
(09) Use a square to enclose the scope
(10)if (the square is beyond the bounds of the image=false)
(11)   Increase the square by a factor of k
(12)end if
(13) Cut out the square to form a smaller picture
(14) Save this picture
(15)end
