MATLAB与OpenCV图像处理基础** 图像处理是利用计算机对图像进行分析和处理,以提取有意义的信息。MATLAB和OpenCV是两个广泛用于图像处理的工具,它们提供了一系列功能强大的函数和库。 MATLAB是一个交互式技术计算环境,具有强大的矩阵操作能力。它提供了图像处理工具箱,其中包含用于图像读取、显示、增强、分割和特征提取的函数。 OpenCV是一个开源计算机视觉库,专注于实时图像处理。它提供了广泛的图像转换、操作、分析和识别功能。OpenCV通常用于嵌入式系统和实时应用程序,因为它高效且易于集成。 # 2. 图像处理算法与技术 ### 2.1 图像增强 图像增强是改善图像质量和可视性的过程,使其更适合特定任务或应用。 #### 2.1.1 直方图均衡化 直方图均衡化是一种图像增强技术,通过调整图像的直方图,使其分布更均匀。这可以提高图像的对比度,增强细节和特征。 ```matlab % 读取图像 image = imread('image.jpg'); % 计算图像直方图 histogram = imhist(image); % 进行直方图均衡化 equalized_image = histeq(image); % 显示原始图像和均衡化后的图像 figure; subplot(1,2,1); imshow(image); title('原始图像'); subplot(1,2,2); imshow(equalized_image); title('直方图均衡化后的图像'); ``` **逻辑分析:** * `imread` 函数读取图像文件并将其存储在 `image` 变量中。 * `imhist` 函数计算图像的直方图并将其存储在 `histogram` 变量中。 * `histeq` 函数执行直方图均衡化并返回均衡化后的图像,存储在 `equalized_image` 变量中。 * `imshow` 函数显示图像,`title` 函数设置图像标题。 #### 2.1.2 图像锐化 图像锐化是增强图像边缘和细节的过程。它可以提高图像的清晰度和可辨识度。 ```matlab % 读取图像 image = imread('image.jpg'); % 高斯滤波器去噪 gaussian_filtered_image = imgaussfilt(image, 2); % 拉普拉斯滤波器锐化 sharpened_image = imfilter(gaussian_filtered_image, fspecial('laplacian')); % 显示原始图像和锐化后的图像 figure; subplot(1,2,1); imshow(image); title('原始图像'); subplot(1,2,2); imshow(sharpened ```
