First, original co-occurrence matrix feature parameters of wood were extracted in noise condition, earned on feature selection, and constructed parameter system of wood texture. 首先在无噪声的环境下提取了木材的共生矩阵纹理原始特征参数,并对其进行特征选择,进而建立了木材纹理参数体系。
Cleaning exposed the grain of wood. 清洁使木纹显现可见。
In splitting wood,don't try to go against the grain. 劈木柴时,要顺着木纹劈。
