| Abstract: | The paper presents a lossy image compression algorithm based on Wavelet transformation to solve the problem that the storage space of PDF 2d barcode is very limited. With the algorithm, the static image information can be added into PDF 2d barcode, and images can be compressed with the pre-specified bytes in high quality. After analyzing Wavelet transformation theories, the paper introduces an improved PDF 2d barcode image compression encoding algorithm. The paper also gives some experimental results and some comparison analyses with the results obtained with FC2VQ algorithm. |
