基于opencv的Python图像处理

图像的打开：

import cv2filename = "/home/vickyleexy/PycharmProjects/33.jpg"img = cv2.imread(filename)print type(img),img.shape,img.dtypecv2.namedWindow("xiamu")cv2.imshow("xiamu",img)cv2.waitKey(0)cv2.destroyAllWindows() #销毁窗口

使用opencv打开图像时报错：
error: /io/opencv/modules/highgui/src/window.cpp:565: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow

但检查发现gtk什么的已经安装了……
解决方法：
sudo apt-get install python-opencv
同时卸载之前安装的opencv-python
sudo pip uninstall opencv-python

opencv安装：
