    摘要:

    應(yīng)用CT技術(shù)掃描不同貯藏期的富士蘋果，獲取含有不同貯藏期信息的CT圖像,，并對(duì)CT圖像及圖像直方圖進(jìn)行對(duì)比分析,。結(jié)果發(fā)現(xiàn),蘋果的CT圖像隨著貯藏時(shí)間的延長(zhǎng)呈現(xiàn)增亮的趨勢(shì)，直方圖呈現(xiàn)明顯的雙峰特性,，其中代表果肉區(qū)域的右峰隨著貯藏時(shí)間的延長(zhǎng)而呈現(xiàn)右移的趨勢(shì),。設(shè)計(jì)了一種簡(jiǎn)單快速的圖像處理算法，計(jì)算CT圖像的特征點(diǎn)灰度均值,，將其與貯藏時(shí)間相對(duì)照,，建立圖像平均灰度值與貯藏時(shí)間的線性關(guān)系。實(shí)驗(yàn)驗(yàn)證表明該模型的預(yù)測(cè)誤差較低,，平均誤差

    Abstract:

    1.08d,。Computed tomography（CT） images and histograms scanned of Fushi apples in different storage time were compared and analyzed. It’s found that the images were getting brighter with the storage time increased and the right peaks of the histogram were moving right. The average gray value of the CT images was calculate to design a simple and fast image processing algorithm. The linear relationship was established between the average gray value and the storage time. The prediction error of the model was low and the average prediction error was 1.08d. 
