将K均值算法用于图像分割,输入的是彩色图像,转换为灰度图像进行分割,输出结果为灰度图像.利用灰度做为特征对每个像素进行聚类,由于光照等原因,有时应该属于一个物体的像素,其灰度值也会有很大的差别,可能导致对该像素的聚类发生错误.在分割结果中,该物体表面会出现一些不同于其它像素的噪声点,因此,算法的最后,对结果进行一次中值滤波,以消除噪声,达到平滑图像的作用-The K means algorithm for image segmentation, the input is a color imag

对电路板的图像进行分割,可以提取电路板中的目标物,以对电路板进行检测。文章使用K均值聚类算法完成对电路板图像的分割,针对传统的K均值聚类算法的不足,提出了使用直方图波形的有效波峰个数来确定K值的大小,并通过使用一种比传统的绝对误差的表示更简洁的表达式,达到了快速分割的目的。对一些电路板图像分割的实验结果表明,文章的方法能够根据目标物的数目有效的确定K值的大小,且比传统的K均值算法减少了运算量及计算时间。-On the circuit board image segmentation, to ex
