$image->writeImage($_SERVER."/test/equalizeImage.png") Īssume that the following is the input image (image. Found 17 RPM for histogram.so Package, Summary, Distribution ImageMagick-6.7.5., An X application for displaying and manipulating images. The final output image is obtained in the format ‘equalizeImage.png’. ImageMagick® is a free and open-source software suite for displaying, converting, and editing raster image and vector image files. The input image is read after creation of imagick object and then ‘equalizeImage()’ function is applied on that input image. This example shows the implementation of ‘equalizeImage()’ function in PHP. It takes an image as input and produces the equalized image as output. In this section, you will be learning to equalize an image using the ‘equalizeImage()’ function provided by Imagemagick. In this process, the contrast can either be increased or decreased based on the histogram equalization which is a computer image processing technique. Equalizing can help bring out details in shadows and highlights, as well as improve color accuracy and reduce noise. So the best you could do would be: convert penguinsonice. $image->writeImage($_SERVER."/test/enhanceImage.png") Īssume that the following is the input image (image.jpg) in the program − Output Equalizing imagesĮqualizing images is a process of adjusting the contrast and brightness in an image to make it look more balanced. 1) IM can only create histograms for up to 1024 colors.
