If you are trying to display OpenCV image using matplotlib, use the code below. import numpy as np import cv2 import matplotlib.pyplot as plt %matplotlib inline # if you are running this code in Jupyter notebook # reads image 'opencv-logo.png' as grayscale img = cv2.imread('/path_to_...
调用matplotlib进行图片展示时,需要注意调整图片的通道顺序,因为opencv读取图片的通道顺序是BGR,而matplotlib是RGB,即在调用plt.imshow之前将image的通道调整为RGB即可。 %matplotlib inline from matplotlib import pyplot as plt import cv2 img = cv2.imread('image.jpg') print('图片属性: {}'.format(img.shape))...
【opencv】python配置opencv环境后,读取图片,报错:can't open/read file: check file path/integrity 1、报错原因 路径中出现中文字符 2、处理方法 修改文件路径为英文 参考链接: https://blog.csdn.net/qq_54000767/article/details/129292229
在尝试对高码流的视频进行rtsp推流后,opencv取流的时候出现: [h264 @ 0x7fd990026040] left block unavailable for requested intra4x4 mode -1 [h264 @ 0x7fd990026040] error while decoding MB 0 18, bytestream 269 1. 2. 而低码流基本没有出现过,视频能顺利分析完,再经过不断优化后,最终能适应4M左...

opencv基于win7的vs2013环境配置了好几天,我放弃了,一个是笔记本64的固态系统盘带起来太吃力了,第二个vs2013c++一直不能正常运行opencv代码,应该是win7系统的环境配置问题,曲线救国,先用自己熟悉的python+pycharm入门吧。网上的资料大多是c++的,还大都是opencv2的。晕'' ...
