%STRETCHLIM Find limits to contrast stretch an image. % 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 h...
接下来,我们将使用以下代码示例来增加图像的对比度: importcv2importnumpyasnpdefincrease_contrast(image,alpha,beta):new_image=np.zeros(image.shape,image.dtype)foryinrange(image.shape[0]):forxinrange(image.shape[1]):forcinrange(image.shape[2]):new_image[y,x,c]=np.clip(alpha*image[y,x,c]...

This is often a good way to normalize image intensity before further processing and also a way to increase image contrast. The transform function is, in this case, a cumulative distribution function (cdf) of the pixel values in the image (normalized to map the range of pixel values to the...
