摘要
利用小波变换对机织物图像进行多层离散小波分解和单层信号重构,对重构后的经纬纱线图像分别沿经纬纱线方向求出亮度平均值,根据亮度信号求出其周期,进而精确求出纱线的经纬密度。
Process multiplayer two-dimensional discrete-wavelets decomposition on woven fabric image and reconstruct monolayer signal with wavelets transformation, then figure out the average value of the reconstructed horizontal and vertical images brightness along the horizon.al and vertical direction respectively. Their periods were figured out according to the brightness signals, then get the density of yarn accurately.
