The paper is committed in local image enhancement. At first, the authors propose an adjacent pixel gray order-preserving principle. Adjacent pixel gray order-preserving principle is the basement of local enhancement method which ensures that there is no distortion in processed image. And then, the authors propose an iterative algorithm, which could stretch gray-scale difference of adjacent pixels in premise of not changing gray magnitude relationship between adjacent pixels. At last, the authors propose a totally reference image quality assessment method based on adjacent pixel gray order-preserving principle. According to this quality assessment method, the authors made a set of comparative experiments with local histogram equalization and method. Experimental results show that the proposed enhancement method can get higher score and provide better visual effects, fully demonstrating its effectiveness. According to this quality assessment method, the proposed method shows a good effectiveness, through experimental results and comparison with local histogram equalization method.

In order to put the parallel one-way hash function into engineering  two designing models based on pipeline technology are proposed in this paper. The definition of one-way hash function is shown first  and the structure and limitation of the current hash functions are discussed afterward. By analyzing the difference between parallel computation on different platforms and classifying one-way hash functions on application basis  the possibility and method of parallel one-way hash function designing on different hardware platforms are described  two designing models are constructed for the parallel one-way hash function designing. Finally  some attentions for designing are proposed from the engineering angle. The pipeline models that proposed in this paper contact the theoretical rationality and the engineering application of parallel one-way hash function together  which can improve the practicality of parallel one-way hash function to a great extent. 2010 IEEE.

The first impression of any building to a person is its exterior and decoration  therefore  at the same time  and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference  how to grasp and control the color change of building materials  the color difference problem laying stone materials is also studied in this paper  which exists universally at the common project  and carry out color quantification  and the solution scheme has been given using this system.  and is often found at the high-grade decoration  it has the very important meaning. According to the color theory  a computer vision system used in color quantification measurement is established  the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation  the mutual conversion between RGB and XYZ color space is studied  which is realized by the BP network. According to the colorimetry theory  the computer program is compiled in order to establish the software system  and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials  and L*a*V model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment  it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
