The negative of an image is achieved by replacing the intensity i in the original image by i-1, i.e. the darkest pixels will become the brightest and the brightest pixels will become the darkest. Image negative is produced by subtracting each pixel from the maximum intensity value.
Lets do it import cv2. import matplotlib.pyplot as plt. imgpath = test.tiff img = cv2.imread(imgpath) img = cv2.cvtColor(img, cv2.COLORBGR2RGB) gray = cv2.imread(imgpath, 0) colorednegative = abs(255-img) graynegative = abs(255-gray) imgs = [img, gray, colorednegative, graynegative]
Image Negative is a typical grey scale transformations that does not depend on the position of the pixel in the image. compressing the darker-level values. The picture will become darker.
You have now captured an image on your film. When that film is processed, it reverses the tones of the subject. In simple terms, the image is dark where the subject was light, and light where the subject was dark. That resulting image is known as a negative.
A negative image is a total inversion, in which light areas appear dark and vice versa. A negative color image is additionally color-reversed, with red areas appearing cyan, greens appearing magenta, and blues appearing yellow, and vice versa.
The negative transformation is given by s=L-1-r. When an image is inverted, each of its pixel value r is subtracted from the maximum pixel value L-1 and the original pixel is replaced with the result s. Image inversion or Image negation helps finding the details from the darker regions of the image.
