＜正＞Digital halftoning is a technique used for binary devices such printers to simulate the continuous tone image. But the quality of halftone prints produced by printers can be limited by random dot-placement errors. In this paper, we propose a printer model and human visual model based method on tone-dependent error diffusion （TDED）. First we analyses the Printer Model and HVS （Human Visual System） used in halftoning algorithm. And based on the Floyd-Steinberg error diffusion algorithm, we train the tone-dependent weights matrix on the different tones using an error within a human visual system. In the experiment, we use HP LaserJet 1010 printer and simulated printer to test the result and compare the quality of the halftone image created by the new algorithm, and both them show very good halftoning quality.

＜正＞The paper attempts to use Low-tempreture Plasma（LTP） technology to improve the surface energy, the coarse degree and the oil ink adhesive force of plastic films by introducing LTP method to the printing and packaging field, consequently improving its printability. The experiments were done at different conditions including time, pressure and plasmas（ Ar、O2、N2、Ar/ 02）. The results of the experiments were measured and analyzed by AFM, the oil ink adhesive force, the critical surface tension, contacting angle and XPS. The best treatment condition based on present equipment is found out by comparing a mass of experimental data and analysing results. Finally, we achieved the best condition of Low-tempreture Plasma（LTP） improving the printability of PE film.

In this paper, we put forward a fault diagnosis system based on multisenor and probabilistic neural networks （PNN）. The multisensor is employed as an effective direct abstracting tool for the frequency segments features of the field signal. The fault signals are dealt with by using probabilistic neural network estimating models. Simulation results show that the proposed method is featured by swiftness, accuracy and ease of practical application.

Adaptive Image Compression based on Visual Masking Effect

第一届图像传播国际会议

作者： Zhigao Yang Yaohua Yi Qianqing Qin State Key Laboratory of Information Engineering in Surveying Mapping and Remote Sensing Wuhan University 129 Luoyu Road Wuhan China 4.0079 school of printing and packaging Wuhan University 129 Luoyu Road Wuhan China 4.0079

＜正＞In low bit rate coding, image compression methods aimed at minimum mean square error may lose the detail and weak information in original images, especially for smoothness areas and edges with low contrast. This is known as "smoothing" effect. Through analysis of the generation mechanism of compression distortion, we propose a visual masking effect based adaptive image compression algorithm that can reduce the "smoothing" effect in low bit rate coding. For the reason that images should be modeled as non-stationary information resources, we use blocking wavelet transform. The decomposition levels of a block are determined by texture complexity of that block. In quantization and entropy coding of wavelet coefficients, we integrate the visual masking effect. Adaptive bit rate allocation is employed to reduce distortion of weak information. Experiments by comparing with baseline JPEG2000 show that visual quality in low bit rate coding is improved significantly, and more weak information is reserved.
