实现功能: 基于OpenCV实现单图像超分辨重建。 实现代码: import cv2 import numpy as np from cv2 import dnn_superres import time import os, random, shutil from PIL import Image #===从文件夹中按数量随机选取一定数量图片移动到另一个文件夹=== def Superresolution(fileDir,tarDir): pathDir = os.lis...

setModel("edsr", 3) # Upscale the image result = sr.upsample(image) # Save the image cv2.imwrite("./upscaled.png", result) 代码相对简单,参考相应的注释即可。 5. 推荐模型 目前在OpenCV中主要支持4种不同的SR模型。它们都可以按2、3和4的比例放大图像。LapSRN甚至可以升级8倍。它们在准确性、...
OpenCV Resize Image - We learn the syntax of cv2.resize() and how to use this function to resize a given image. We can use cv2.resize() function to upscale, downscale, or resize to a desired size (considering or not considering the aspect ratio).

$image = cv\imread(“images/faces.jpg”); 相比之下,在 python 下图像加载是这样的: image = cv2.imread(“images/faces.jpg”) 当在PHP(以及在 C++中)中读取一张图像时,信息就存储在 Mat 对象(矩阵)中。在 PHP 中,类似的是一个多维数组,但又与多维数组有所不同,该对象可以进行多种快速操作,例如,...
