    摘要:

    以“中棉35”棉花種子為對象,，應(yīng)用圖像處理技術(shù),，提出了基于形態(tài)學(xué)的破損識別方法,。采用鏈碼算子獲取輪廓信息并進(jìn)行傅里葉算子平滑，根據(jù)曲率特征定位輪廓尖端點后,，通過輪廓的對稱性識別局部破損棉種,；基于統(tǒng)計思想，根據(jù)大小,、形狀特征的差異識別嚴(yán)重破損棉種,。選取完好、破損棉種各200粒進(jìn)行識別試驗,，結(jié)果表明破損棉種識別率達(dá)到

    Abstract:

    94％,。Taking the seeds of “Zhongmian 35” as research objectives, a method of surface damages detection was developed based on morphology of cottonseed by the digital image technology. The boundary was picked up with chain code operator and smoothed by the Fourier operator. Find the tip of the cottonseed after analyzing the curvatures of contour points. Detect the local damaged cottonseeds according to the symmetry of the boundary. Area and elongation were used to identify seriously damaged cottonseeds with statistical method. The experiments show that the detecting accuracy is 94% with 200 damaged cottonseeds and 200 cottonseeds without damages.
