2. 特征点检测 综合考虑拼接效率和准确度,这里选择使用SIFT特征点检测算法,详情可以参考opencv文档相关教程(https://docs.opencv.org/3.4/da/df5/tutorial_py_sift_intro.html) # 使用SIFT检测器 sift = cv2.SIFT_create() # 检测关键点和描述符 keypoints1, descriptors1 = sift.detectAndCompute(image1_resiz...
OpenCV means Open Source Computer Vision Library. It is an open source computer vision library and it has bindings for C++, Python, and Java. It is used for a very wide range of applications including medical image analysis, stitching street view images, surveillance video, detecting and ...
Image Processing In today’s post we will describe a class of region filling algorithms called image inpainting. Imagine finding an old family photograph. You scan it and it looks great except for a few scratches. Of course you can load the photo in Photoshop and fix the scratches. But is...
flags = [iforiindir(cv2)ifi.startswith('COLOR_')]print(flags) 注意: 对于HSV来说,Hue范围是[0, 179], Saturation范围是[0, 255],Value范围是[0, 255]。不同的软件用不同的刻度(scales)。所以当你比较它们的OpenCV值,你需要标准化它们的范围。 1.3 对象跟踪(Object Tracking) 现在我们知道如何将图像...
In this step-by-step tutorial, you'll learn how to use the Python Pillow library to deal with images and perform image processing. You'll also explore using NumPy for further processing, including to create animations.

使用OpenCV和Python添加噪声 1. 添加高斯噪声 ```python import numpy as np import cv2 def add_gaussian_noise(image, mean=0, sigma=25): h, w, c = image.shape gauss = np.random.normal(mean, sigma, (h, w, c)) noisy_image = np.clip(image + gauss, 0, 255).astype(np.uint8) ...
PyImageSearchProblems - Kudos to Adrian for his awesome blog on image processing in opencv - PyImageSearch. The files in this folder mostly follow some of his blogs with my flavor to the problems here and there. PythonProjects - My playground! Every time someone mentions or I think of an...
Python中Opencv和PIL.Image读取图片的差异对比 近日,在进行深度学习进行推理的时候,发现不管怎么样都得不出正确的结果,再仔细和正确的代码进行对比了后发现原来是Python中不同的库读取的图片数组是有差异的。 image = np.array(Image.open(image_file).convert('RGB'))...
Computational photography is about enhancing the photographic process with computation. While we normally tend to think that this applies only to post-processing the end result (similar to photo editing), the possibilities are much richer since computati
