摘　　要：为了对显微图像进行有效统计与测量,提出了一种以DSP为核心的嵌入式图像采集处理系统,设计了基于DSP/BIOS的应用程序。首先利用中值滤波、自适应阈值分割等算法对图像进行预处理,将目标从背景中分离出来,然后采用扫描标记的算法对目标加以标记,最后实现对目标的数目及面积等几何尺寸的测量。In order to achieve effectively statistics and measurement of micrograph, an embedded image gathering and processing system which take a DSP as the core processor is put forward. The application program is designed based on DSP/BIOS. Using median filtering and auto-adapted threshold algorithms, the micrograph is preprocessed firstly, which could separate the objects from the background. Then the objects are labeled through the scanning labeling algorithm. Finally, realizes the measurement of the object＇s number and the geometry parameters sucb as area etc.
