要使用的自适应阈值算法,请参阅 AdaptiveThresholdTypes。该 BORDER_REPLICATE | BORDER_ISOLATED用于处理边界。 thresholdType 阈值类型必须是 THRESH_BINARY或 THRESH_BINARY_INV,请参阅 ThresholdTypes。 BLOCKSIZE 用于计算像素阈值的像素邻域的大小:3,5,7等。 C 从平均值或加权平均值中减去常数(请参阅下面的详细信...
borderType为填充类型,如cv2.BORDER_CONSTANT,用常数填充;cv2.BORDER_ISOLATED,用黑色像素填充,等; dts为输出图像; value为常量填充的值,如value=(114,114,114),灰度填充。 示例: import cv2 image_path ='F:/yolov5-personSE/redfruit.jpg' image = cv2.imread(image_path) cv2.imshow('original Image',im...
