对于广泛的应用程序，例如数字库，地图档案，指纹数据库，FACSSILILE等广泛的应用，二进制图像压缩是可取的。在本文中，我们提出了一种新的高效算法，用于无损二进制图像压缩。提出的算法引入了一种新方法，即直接冗余消除，以有效利用图像的二维冗余，以及一种新型的动态上下文模型，以提高算术编码的效率。仿真结果表明，所提出的算法与JBIG标准具有可比的压缩比。在许多情况下，提出的算法优于JBIG标准
Binary image compression is desirable for a wide range of applications, such as digital libraries, map archives, fingerprint databases, facsimile, etc. In this paper, we present a new highly efficient algorithm for lossless binary image compression. The proposed algorithm introduces a new method, direct redundancy elimination, to efficiently exploit the two-dimensional redundancy of an image, as well as a novel dynamic context model to improve the efficiency of arithmetic coding. Simulation results show that the proposed algorithm has comparable compression ratio to JBIG standard. In many cases, the proposed algorithm outperforms the JBIG standard
