3. Digital Image Processing Theory and Applications

Heads: Qingsheng Zhu

Introduction:
The early work on digital image compression was mostly focused on the analysis and operation in the time region or space region or frequency region, making only use only of part of the image characteristics. To enhance the compression ratio as well as shorten the needed time, it is necessary to utilize the characteristics of more than one region. A group of young teachers in our college have been indulging in the research of this subject for quite a few years. In 1998, we completed ??Remote Measuring Data Compression System?ˉ, the project of Chinese Aeronautical Industry Main Corporation. The algorithm therein was evaluated as internationally advanced both in the compression ratio and the operation time. Thereby we received the second-rank award of Chinese National Defense Science and Technology Progress. In 1999, we finished ??Research of Wavelet Theory and Data Compression Technology?ˉ, the National Education Ministry?ˉs Excellent Young Teacher Fund Project, by presenting a series of compression algorithms. Also, these algorithms were evaluated as internationally advanced by many famous specialists.
We have published more than 20 papers in the field of image reconstruction algorithm with applications in ICT. Of them, two were in Electronica Sinica, and one was collected in Chinese Journal of Computers. Based on this, we have successfully finished one National Natural Science Fund Project. Remarkably, we have successfully applied our image reconstruction algorithms to the ICT technology and thereby realized the lossless test of various equipments. These results have been used in the national defense field. Moreover, we have received the second-rank awards of both the National Education Ministry?ˉs and Sichuan?ˉs Science and Technology Progress.
We have made a deep research on the wavelet theory and the algorithms involved in the data compression, and thereby have proposed a series of novel compression algorithms. Some of our main results are listed below:
(1) A necessary and sufficient condition for a bi-orthogonal wavelet that is built by using a bi-orthogonal perfect reconstruction filter bank was proposed, and thereby a construction method for a bi-orthogonal wavelet was given. This method enjoys the striking advantage of approximating the ideal low-pass filter and the ideal high-pass filter simultaneously by the numerical optimization method.
(2) A compression method was proposed by using the forecasting of the wavelet coefficient within a single frame. The basic idea is to make a forecast by making full use of both the correlations between different scales in the same direction and the zero coefficient blocks. As a result, the redundancy in the space is greatly diminished.
(3) A wavelet-oriented bit allocation algorithm was described. This algorithm can adjust the compression ratio of the image flexibly. On the other hand, it can achieve nearly the best quality of the reconstructed image quality given the compression ratio. Therefore, it is applicable to the applications where bit allocation is needed or changeable compression ratios are taken into consideration.
(4) A lossless coding algorithm that is based on higher-order dynamic lexicon model was presented. Compared with the early algorithms, our algorithm achieves a better trade-off among a number of main indexes.
It bears not only theoretical importance but also widespread application potentials to study multimedia data compression and relevant practical system. Quite recently, we have undertaken ??Compression System for the Document Scanning Image Data?ˉ, the Chongqing?ˉs Attacking Project. Our goal is to exceed existent algorithms in terms of the compression ratio and embed the new algorithms into real software system.
