| Abstract: | An efficient compression technique for the text images was studied by the combination of binary of images, dada subsampling and spline interpolation to achieve an efficient compression method for the text images. This technique has simply computational structure, lower complexity and high quality of a compressed image. Experimental results show that the compression ratio is more than 110 times with the high quality of compressed images. |
