【摘要】：近些年,X射線技術(shù)已開始應(yīng)用于海產(chǎn)魚片中魚骨刺的檢測。為提高X射線檢測鮐魚片中魚骨刺的圖像質(zhì)量,進(jìn)而提高殘留魚骨刺檢出率,研究了6種不同的X射線圖像增強(qiáng)處理技術(shù)(正反相線性增強(qiáng);數(shù)學(xué)形態(tài)學(xué)增強(qiáng);對比度增強(qiáng);掩模銳化圖像;高斯低通濾波;受限對比度自適應(yīng)直方圖均衡化),以圖像質(zhì)量主觀評價和檢出率為指標(biāo),評價鮐魚片中魚刺的檢測效果。結(jié)果表明,在X光機(jī)切身4檢測模式下,對比度增強(qiáng)和掩模銳化圖像兩種方法為整體圖像增強(qiáng)的最佳選擇,正反相線性增強(qiáng)和受限對比度自適應(yīng)直方圖均衡化兩種方法在特殊部位(腹部和魚肉邊緣)的圖像處理方面也有可以借鑒應(yīng)用的潛力。通過多種圖像增強(qiáng)算法的比較,篩選得到的增強(qiáng)方案可以改善圖像質(zhì)量和提高殘留魚骨刺檢出率,改善水產(chǎn)品加工企業(yè)X光機(jī)檢測人員的視覺感受,并一定程度上降低魚片產(chǎn)品魚刺殘留問題的投訴頻率。
[Abstract]:In recent years, X-ray technology has been applied to the detection of bone spines in fish slices. In order to improve the image quality of fish bone spines in mackerel slices detected by X-ray, and to improve the detection rate of residual fish bone spines, six different techniques of X-ray image enhancement (linear enhancement, mathematical morphology enhancement, contrast enhancement) were studied. Mask sharpening image; Gao Si low-pass filtering; constrained contrast adaptive histogram equalization), image quality subjective evaluation and detection rate as indicators to evaluate the effectiveness of fish burr detection in mackerel slices. The results show that contrast enhancement and mask sharpening are the best methods for overall image enhancement in the mode of X ray machine body 4 detection. Positive and inverse linear enhancement and constrained contrast adaptive histogram equalization can also be used for reference in image processing of special parts (abdomen and fish edge). Through the comparison of various image enhancement algorithms, the enhancement scheme can improve the image quality and the detection rate of residual fish bone spines, and improve the visual perception of X-ray machine inspectors in aquatic products processing enterprises. And to a certain extent to reduce the residue of fish fillet products complaints about the frequency.
