WebMar 21, 2012 · logaritmic transformations (using c*log (1+f)) usually, logarithmic transformation used to brighten the intensities of an image of lower intensity values. its function in matlab can be shown as, g = c*log (1+double (f)) . here, we paste some matlab code example for logaritmic transformation :) >> I = imread ('tire.tif'); >> I2=im2double (I); WebEDIT: If you want to convert your indexed image to a grayscale image, matlab provides the ind2gray function, e.g.: [img, map] = imread ('lena.bmp'); img_gray = ind2gray (img, map); This is probably what you need if you mean to process pixel values as intensities. Share.
WebJan 26, 2024 · Like log transformation, power law curves with γ <1 map a narrow range of dark input values into a wider range of output values, with the opposite being true for higher input values. Similarly, for γ >1, we get the opposite result which is shown in the figure below This is also known as gamma correction, gamma encoding or gamma compression. WebConsider the general problem of contrast enhancement, one of the principal applications of intensity transformations.We can state the process of enhancing the contrast of a gray-scale image using the following rules: IF a pixel is dark, THEN make it darker. IF a pixel is gray, THEN make it gray. IF a pixel is bright, THEN make it brighter.
