亲亲,这里是一个使用 MATLAB 处理图像的常见示例代码,用于读取图像并对其进行一些基本操作(转换为灰度图像、对比度增强、二值化):```matlab% 读取图像img = imread('your_image.jpg');% 将图像转换为灰度gray_img = rgb2gray(img);% 调整图像对比度high_contrast_img = imadjust(gray_img);% ...
将'path_to_save_contrast_adjusted_image.jpg'和'path_to_save_brightness_adjusted_image.jpg'替换为你想要保存图像的路径和文件名。 通过以上步骤,你可以在MATLAB中轻松地调整图像的对比度和亮度,并显示或保存调整后的图像。

LOW_HIGH = STRETCHLIM(I,TOL) returns a pair of gray values that can be % used by IMADJUST to increase the contrast of an image. % % TOL = [LOW_FRACT HIGH_FRACT] specifies the fraction of the image to % saturate at low and high pixel values. % % If TOL is a scalar, TOL = LO...
image(x,y,C) 在(x,y)确定的位置上画C的元素。其中x,y都为2维矩阵,分别指定x轴与y轴的范围,其效果与image(C)相同,只不过是进行了恰当的比例缩放。 image(x,y,C,'PropertyName',PropertyValue,…) 该形式为指定属性名/属性值的高级使用形式,在执行该命令之前,先执行命令newplot。
The code tries to enhance the low contrast image by making its histogram modified so that it matches the histogram of high contrast image. Cite As AliArshad Kothawala (2025).

1. 'Contrast' : 对比度。返回整幅图像中像素和它相邻像素之间的亮度反差。取值范围:[0,(GLCM行数-1)^2]。灰度一致的图像,对比度为0。2. 'Correlation' : 相关。返回整幅图像中像素与其相邻像素是如何相关的度量值。取值范围:[-1,1]。灰度一致的图像,相关性为NaN。3. 'Energy' : 能量...
你可以直接在命令行里输入 help stretchlim 获得图像对比度拉伸范围 应用举例:clc; clear all; close all;I = imread('pout.tif');J = imadjust(I,stretchlim(I),[]);figure;subplot(1, 2 ,1); imshow(I); title('原图像');subplot(1, 2, 2); imshow(J); title('结果图像'); book...
