Abstract
One embodiment of the present invention provides a system that removes noise from an image. During operation, the system first identifies blobs in the image, wherein a blob is a set of contiguous pixels which possibly represents a character or a portion of a character in the image. Next, the system analyzes the blobs to dynamically determine a 'noise threshold' for the blobs. The system then removes blobs from the image which are below the noise threshold.
