“output” is the negative of the input image and the same displaying and writing is done. After that a new window is created, image is displayed with title “grayscale image” and written as “original.jpg”. Now image is read and converted to grayscale.

The first 3 lines clears the variables in memory, closes all opened windows and clears the terminal. Now let’s implement this in Matlab: clear all % clear all variables close all % close all figures clc % clear command window % import image package pkg load image % read image img = imread(“lena.png”) % convert image into gray and then from uint8 to double grayscale_img = rgb2gray(img) % show grayscale image figure imshow(grayscale_img) title(“grayscale image”) imwrite(grayscale_img, “original.jpg”) # calculate negative of the image output = 255 - grayscale_img % show output image figure imshow(uint8(output)) title(“output image”) imwrite(uint8(output), “negative_tansformation.jpg”) Where, L-1 = 255, for gray image and I is the image pixels. The negative of an image is just the subtraction of pixel values from 255 for a gray image. Where, (x, y) are the coordinates of the pixels, F is the input image, G is the enhanced image and T is an operator on F. In spatial domain the image manipulation is done directly on the pixels of an image. Image enhancement approaches fall into two broad categories: Spatial domain and Frequency domain. The motive of enhancement is to process an image so that the result is more suitable than the original image for a specific application. RGB → HSV: hsv_image = rgb2hsv(rgb_image) Image Enhancement RGB → Gray: gray_image = rgb2gray(rgb_image) Additional functions in Matlab/Octaveįirst, we’ll see how to read/write images in Matlab and display them.įor converting between images there are built-in functions in Matlab, such as:
and/or other countries.Here, you can see that the deeper in the cone towards bottom, the darker is the color(value), on the edges of the cone the color is the brightest (Saturation) and about the circumference you can see different colors (Hue).
