Yueqiu Jiang, Lei Jin, Hongwei Gao
It is a frequently encountered problem to calculate the area of target region in image processing. Based on an improved algorithm of contour extracting, a method for calculating the area of target region was advanced. First, the contour is extracted from the binary image, while note the location and type information of the contour points. Next, the area of target region is calculated by weighting summation of the contour points. Experimental results show this method is simple and easy to implement.

Online Dynamic Control of Secondary Cooling for the Continuous Casting Process 连铸过程二次冷却的在线动态控制
Zhenping Ji, Jian Yang
Aiming to reduce the occurrence of the surface and internal defects in the products, a dynamic secondary cooling control system was developed. The purpose of the system was to keep the surface temperature of the strand constant regardless of changes in casting speed. To accurately predict and control temperature in real time during the continuous casting process, A fast, accurate transient solidification and heat transfer model that serves as a “software sensor” was developed, which provide feedback to a control system. The control methodology and software suitable for online control of continuous casting cooling process were also designed. In order to maintain the target temperature profile throughout the steel, the new software system continuously read the operating conditions and adjusts the spray-water flow rates in the secondary cooling zone of the caster. The control system is demonstrated by simulation and the results show that the control system is capable of running in real time on billet caster.

A High-Speed Data Transmission Design Using Single-Core Cable 基于单芯电缆的高速数据传输设计
Liusha Yang, Su YunTao
The single-core cable is used in production logging to achieve data transmission between the surface and the underground. However, for the narrow band of the single-core cable, using the traditional base-band modulation, transfer rate is very difficult to rise. Lower transfer rate limits the development of underground equipments. This paper analyzes the characteristics of single-core cable, combined with the actual situation of production logging, based on orthogonal frequency division multiplexing, we design high-speed logging data transmission system and improve the bandwidth efficiency, so it is a kind of ideal data transmission for production logging. The system can realize the transmission rate of 115kbps or more in the 7,000 meters Camesa anti-hydrogen sulfide single-core cable. In laboratory conditions, the system withstands the test of high temperature for two hours. The system is stable and lays a solid foundation to test in the well site.

Novel Image Enhancement Algorithm Based on Wavelet Multiscale 基于小波多尺度的图像增强新算法
Yan Qi, Li Ren
Traditional algorithm of image enhancement enhances the contrast grade and noise of image at the same time. So, noise reduction is needed. Wavelet enhancement considers the spatial domain and frequency domain of image signal, but not the nonlinearity of vision. Aim at the problem of enhanced noise in image enhancement, a new algorithm for image enhancement based on wavelet multiscale is proposed by analyzing the effects of wavelet on signal and noise regularity. Making use of the correlation of the wavelet coefficient from different scales and the frequency localization of wavelet, the noise and image information is divided effectively. It can alleviate the noise amplification while enhancing the image feature.
传统的图像增强算法是在增强图像对比度的同时增强图像的噪声。因此,降噪是必要的。小波增强考虑的是图像信号的空间域和频域,而不是视觉的非线性。针对图像增强中存在的噪声增强问题,通过分析小波对信号和噪声规律的影响,提出了一种基于小波多尺度的图像增强算法。利用小波系数在不同尺度上的相关性和小波的频率定位,有效地分离了噪声和图像信息。它可以在增强图像特征的同时减轻噪声的放大。

A Fast Intra-frame Prediction Algorithm Based on the Feature of Macro-block for H.264/AVC 基于宏块特性的H.264/AVC帧内快速预测算法
Pengyu Liu, Ke-bin Jia
H.264/AVC is the newest video coding standard with high compression efficiency. Especially it adopts traveling algorithm to find the optimal mode for intra-frame prediction in spatial field, so it is quite complex and costs very long encoding-time. In this paper, the proposed fast mode decision scheme consists of two parts: early intra mode detection, which is to select intra 4×4 or intra 16×16 mode for each MB before encoding according to smoothness characteristic, and fast intra4×4 mode decision, which is to reduce choices of prediction directions from 9 to 3 by SAD of Mode 0 to Mode 2. Experimental results show that without the variety of PSNR basically, the compression time is 32.8% less than the original algorithm, and only increases 3.2% bits-rate on average. This algorithm improves the intra-frame coding efficiency, and is especially applicable for the high quality and complex sequence.
H.264/AVC是最新的视频编码标准,具有很高的压缩效率。特别是在空间场中采用旅行算法寻找帧内预测的最优模式,因此该算法非常复杂,编码时间也很长。本文提出的快速模式决策方案包括两部分:早期模式内检测,即在编码前根据平滑特性为每个MB选择intra4×4或intra 16×16模式;快速intra4×4模式决策,即通过模式0到模式2的SAD将预测方向的选择从9个减少到3个。实验结果表明,在基本没有PSNR变化的情况下,压缩时间比原算法缩短了32.8%,平均比特率仅提高了3.2%。该算法提高了帧内编码效率,特别适用于高质量、复杂序列的编码。
