Description: 衡含水率（EMC）： 湿材置于干燥的环境下中，木材的水分会向周围空气中蒸发。在纤维饱和点以下，每当周围相对湿度发生变化，木材细胞壁中吸着水量也相应地变化。若周围空气的温度较低，细胞壁中的水蒸气分压比空气中的大，则水分由木材向空气中蒸发，使得吸着水含量减少，该现象叫解吸。解吸过程初期，木材的水分蒸发很强烈，随后解吸过程渐缓，最后达到动态平衡或稳定，此时的木材含水率叫解吸稳定含水率。
当周围的湿度较高时，细胞壁中的水蒸气的分压比空气中吸湿，使得吸着水含量增大，此现象为吸湿。木材含水率在吸湿过程中达到稳定值叫吸湿稳定含水率。细薄木料在一定的空气状态下，最后达到解吸稳定含水率或吸湿稳定含水率，叫平衡含水率。
-Balance the moisture content (EMC): The wet material is placed in a dry environment, the timber the water will evaporate to the ambient air. Below the fiber saturation point, whenever the ambient relative humidity changes, the adsorption of water in the wood cell wall change. Lower the ambient air temperature, water vapor partial pressure in the cell wall than the air in the large, the evaporation of water from the timber into the air, so to reduce the adsorbed water content, the phenomenon is called desorption. The beginning of the desorption process, the wood moisture evaporation is very strong, followed by the desorption process gradually slowed, and finally a dynamic equilibrium or stability, the wood moisture content at this time called desorption stable moisture content. When the surrounding humidity is high, the cell wall of water vapor partial pressure than air and moisture, making the adsorbed water content increases, this phenomenon moisture. Wood moisture content reaches a s

Description: 数字图像中的拐点通常成为重要的信息载体，因此准确、稳定和实时地检测出拐点便成为拐点检测算法面l临的主要问题，针对该问题，提出了一种新的二值图像中拐点的实时检测算法。该算法与传统基于边界链码的拐点检测算法不同，其是首先构建像素的k(k>8)邻域，并将图像中物体的边界表示为k邻域链码；然后根据曲率定义的差分形式计算各边界点处的曲率；最后通过检测曲率直方图的局部峰值精确定位出拐点，并利用拐角内部像素的颜色统计信息迅速判断出拐点的凸凹性。(The inflection point in the digital image are important information carriers, so accurate, stable and real-time detection of the inflection point will become the main problem of inflection point detection algorithm face L, to solve this problem, we propose a new two value image in the inflection point of the real-time detection algorithm. The algorithm with the traditional inflection point algorithm of edge detection based on chain code, which is firstly constructed pixel K (k>8) neighborhood, and the image object boundary representation for K neighborhood chain code; then according to the definition of curvature curvature difference form to calculate the boundary point; precise local peak location finally tested by the curvature histogram of a turning point, and the use of internal corner pixel color statistical information to quickly determine the convexity of the inflection point.)

Description: 双峰法阈值分割。阈值分割法是一种基于区域的图像分割技术，原理是把图像象素点分为若干类。图像阈值化分割是一种传统的最常用的图像分割方法，因其实现简单、计算量小、性能较稳定而成为图像分割中最基本和应用最广泛的分割技术。它特别适用于目标和背景占据不同灰度级范围的图像。它不仅可以极大的压缩数据量，而且也大大简化了分析和处理步骤，因此在很多情况下，是进行图像分析、特征提取与模式识别之前的必要的图像预处理过程。图像阈值化的目的是要按照灰度级，对像素集合进行一个划分，得到的每个子集形成一个与现实景物相对应的区域，各个区域内部具有一致的属性，而相邻区域不具有这种一致属性。这样的划分可以通过从灰度级出发选取一个或多个阈值来实现。(Threshold segmentation)
