Abstract

Binary image sometimes shows the random noisy dots and blobs, which are independent of the input data, depending on the illumination condition of the input data and characteristic of an image scanner itself. We propose the binary image enhancement algorithm that smooths out the noise element while preserving thin contours. The proposed algorithm is fast enough to be applicable to nearly real-time services. Computer simulation shows that the proposed method gives better performance than the existing methods in terms of the computational complexity and the effectiveness of the noise reduction with preserving thin contours. It also increases the data compression ratio of the image data based on the G4 facsimile encoding schemes.
