  1. In this paper, the contrast of original image is enhanced by nonlinear transformation based on the characteristics of grain image ; after comparing several methods of threshold segmentation and analyzing their performance and applicability on grain image, the adaptive threshold segmentation based on gradient image is presented ; the noise of binary image is reduced with morphological filter, the hollow in binary image is filled in and a recognition algorithm is designed to remove agglomerate particle ; on the basis of mathematical morphology two methods are adopted to segment agglomerate grains that are not agglomerated tightly ; the parameters of size and shape, perimeter, area, diameter, complexlity, longest feret diameter, shortest feret diameter etc, are extracted. this technique is applied in measurement of pearl powder ' s particle size

    本文根據粒度圖像的特點,採用非線性對度增強處理改善顆粒顯微圖像的對度;對多種閾值分割方法進行較,分析了它們的性能和用於粒度圖像的適用性,在此基礎上提出了一種基於梯度圖像的動態閾值分割方法;對獲取的顆粒二值圖像進行形態濾波和空洞填充,設了識別演算法去除凝聚體;對疊不太嚴的粘結顆粒採用了兩種基於數學形態學的分割演算法;提取了周長、面積、粒徑、復雜度、最長feret徑、最短feret徑等大小和形狀特徵參數,對粉等粉體粒度進行了測量。
