WebPansharpening refers to the super resolution of a low-resolution multispectral (LR-MS) image in virtue of an aligned panchromatic (PAN) image. Such an inverse problem mainly requires a proper use of the spatial information from the auxiliary PAN image. In this paper, we suggest a nonconvex regularization model for pansharpening via framelet sparse … WebMar 13, 2024 · 下面是使用 Python 实现灰度图的直方图均衡化的代码： ```python import cv2 import numpy as np # 读入图像 img = cv2.imread('image.jpg', cv2.IMREAD_GRAYSCALE) # 计算图像的直方图 hist = cv2.calcHist([img], [0], None, [256], [0, 256]) # 计算累计分布函数 cdf = hist.cumsum() cdf_normalized = cdf * hist.max() / cdf.max() # 用累计分布函数计算 …
