python - OpenCV Python 错误 : Unsupported data type (=4) in function 'cv::opt_AVX2::getMorphologyRowFilter'

Question

我正在尝试用形态去除噪音，但内核给了我错误:

import skimage.io as io
import numpy as np
import cv2

c=io.imread('circles.png').astype('bool')*1
x=np.random.random_sample(c.shape)
c[np.nonzero(x>0.95)]= 0
c[np.nonzero(x<=0.05)] = 1

opening = cv2.morphologyEx(c, cv2.MORPH_OPEN, np.ones((2,2),np.uint8))

io.imshow(opening)

错误:

error: OpenCV(4.1.2) C:/projects/opencv-python/opencv/modules/imgproc/src/morph.simd.hpp:756: error: (-213:The function/feature is not implemented) Unsupported data type (=4) in function 'cv::opt_AVX2::getMorphologyRowFilter'

Answer 1

您的数据类型 (=4) 是 CV_32SC1，它是 32 位有符号单 channel - 您需要将数据转换为另一种数据类型，我建议使用 CV_8UC1，因为它具有最小的内存占用和易用性:

c = c.astype('uint8') # or c.astype(np.byte)
