放花灯程序实现步骤: (1) 使用OpenCV鼠标事件绘制矩形截取Rect设置mask(不会的话看我B站的视频教程有详细讲解); (2) 使用seamlessClone完成图像融合。 效果见开头效果视频,源码如下: (1) Python版本: AI检测代码解析 import cv2 import numpy as np flag = False x1=y1=0 def gen_light(rect): global temp2...
opencvapi编程算法 OpenCV3.x的图像计算模块多了新算法API-无缝克隆(Seamless Cloning),主要是针对图像编辑,局部修改等应用场景实现迁移对象与原图像场景的无缝克隆。相关函数与参数说明如下: OpenCV学堂 2018/07/26 1.4K0 OCR -- seamlessClone泊松融合 文字识别pythonhttpsopencv opencv:https://www.learnopencv.com/...

OCR -- seamlessClone泊松融合 https://www.learnopencv.com/seamless-cloning-using-opencv-python-cpp/ OCR工程git:https://github.com/MachineLP/OCR_repo 看到这个题目是不是很突兀啊,OCR和泊松融合又有啥关系呢? 是这样的,因为在训练的时候需要生成训练字体,有时候需要融合不同的背景。 看一下效果: python...
Opencv 3.4.6-dev Python 3.6.8 There is a problem in seamlessClone that was produced by this pr #12512. When mask is on borders only (like border line) it's just crashes. It happens because opencv/modules/photo/src/seamless_cloning.cpp Li...
When I use a function: cv::seamlessClone,work well under normal conditions。 But when I use it in an environment with Pytorch,I got the following mistakes:“Segmentation fault”。 Occurs in the following version: opencv 4.1.1 /opencv 4.2.0 P...
这三个功能在opencv中是同一个函数,使用不同的flag切换不同功能: seamlessClone(src, dst, mask, p, result, flags) color change: 同一幅图像的颜色融合 colorChange(src, mask, result, red_mul, green_mul, blue_mul) 后面三个参数是rgb三个通道的乘数因子,在0.5-2.5之间。值越大起到锐化的作用。
python opencv 将一张图片无缝合成到另一张图片中 原文地址:SeamlessCloningusingOpenCV(Python, C++) 无缝合成(SeamlessCloning)是opencv3的新特性。 利用这个新特性,我们可以从一个图像复制对象,并将其粘贴到另一个图像中,同时使组合看起来无缝和自然。 比如说下面这个图就是飞机和天空无缝合成的结果 想要达到上述效...
