【摘要】 棉纤维成熟度的图象分析包括输入图象的预处理,纤维轮廓的抽取及参数检测。在图象预处理中,首先用中值滤波消除图象中的噪声,然后再二值化。轮廓通过直接跟踪纤维外边界来获得。本文提出了转折点定义,根据轮廓方向链码判别出转折点,再利用奇偶检测测量纤维参数.根据这些参数计算纤维的成熟度。更多还原

【Abstract】 Image analyses on cotton fibre maturity consists of image pre-processing,extraction ofcontour and parameters detection.In image pre-processing,first median filtering is used toeleminate noise,and then threshold begins.The contour of cotton fibre is got by tracing it’souter edge.The turning-points are defined in this paper.With the turning-points determinedaccording to the direction chain code of the contour,the interparameters of the fibre can bedetected by parity check and the fibre maturity can be calculated.更多还原
