write code that applies gamma to an image using intergation in matlab

To apply gamma correction to an image using integration in MATLAB, you can follow these steps:

  1. Read the image from file using the imread function:
    image = imread('image.jpg');

33 chars
2 lines
  1. Convert the image to double to ensure accurate calculations:
    image_double = im2double(image);

37 chars
2 lines
  1. Normalize the intensities to the range [0, 1]:
    image_normalized = image_double ./ max(image_double(:));

61 chars
2 lines
  1. Define the gamma value you want to apply:
    gamma = 2.2;  % You can adjust the gamma value as desired

62 chars
2 lines
  1. Perform gamma correction by raising the intensities to the power of the gamma value:
    image_gamma_corrected = image_normalized .^ gamma;

55 chars
2 lines
  1. Rescale the intensities back to the original range [0, 255]:
    image_gamma_corrected = image_gamma_corrected .* 255;

58 chars
2 lines
  1. Convert the image back to uint8 data type:
    image_gamma_corrected = uint8(image_gamma_corrected);

58 chars
2 lines
  1. Display the original and gamma corrected images:
    figure;
    subplot(1, 2, 1);
    imshow(image);
    title('Original Image');

    subplot(1, 2, 2);
    imshow(image_gamma_corrected);
    title('Gamma Corrected Image');

9 lines

Remember to save the gamma corrected image if you want to use it further:

    imwrite(image_gamma_corrected, 'gamma_corrected_image.jpg');

2 lines

This code will apply gamma correction to the input image using integration in MATLAB.
