这个简单的代码无法正常工作。
output = cv2.namedWindow("Output", cv2.WINDOW_AUTOSIZE)
cv2.imshow(output, saliencyMap)
cv2.waitKey(0)
它应该在saliencyMap
窗口中显示"Output"
,但是它正在生成两个窗口(如下)。我正在使用spyder编辑器,并且也收到此消息。
You might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.
QObject::moveToThread: Current thread (0x7fbf1e53c600) is not the object's thread (0x7fbf1e6f0850).
Cannot move to target thread (0x7fbf1e53c600)`
最佳答案
namedWindow是一个函数,它是void函数,因此它不提供任何输出值。 imshow将字符串和Mat作为输入。
正确的应该是:
import cv2
img = cv2.imread('img.png')
cv2.namedWindow("Output", cv2.WINDOW_AUTOSIZE)
cv2.imshow("Output", img)
cv2.waitKey(0)
