self.btn_convert["state"] = "disabled" 接下来就是转换图像的部分,我们定义一个convert_image方法: 打开用户选择的图片文件,将其转换为灰度图像,然后将图像的灰度值转换为矩阵,并使用numpy.savetxt将矩阵保存为文本文件。保存的矩阵文件名格式为原始文件名_matrix.txt,保存的格式为每三个数字以逗号分隔。如果转换...
gray_image = image.convert('L') 将灰度图像转换为NumPy数组 gray_image_matrix = np.array(gray_image) print(gray_image_matrix) 使用OpenCV库将图片矩阵转换为灰度图像 import cv2 读取图片 image = cv2.imread('path_to_image.jpg') 将图片转换为灰度图像 gray_image = cv2.cvtColor(image, cv2.COLOR_...
print(gray_image_matrix) 五、将图片矩阵转换回图片 有时,我们需要将处理后的图片矩阵转换回图片,可以使用Pillow、OpenCV和scikit-image库实现这一点。 使用Pillow库 from PIL import Image import numpy as np 创建一个随机矩阵 matrix = np.random.randint(0, 256, (100, 100, 3), dtype=np.uint8) 将矩...
下面是一个简单的类图,展示该类的结构: ImageConverter+load_image(file_path: str)+convert_to_matrix()+display_matrix_info() 在ImageConverter类中,我们定义了三个公开方法:load_image()用于加载图像,convert_to_matrix()用于转换为矩阵,以及display_matrix_info()用于显示矩阵的信息。 项目计划 实现图像转换过...
