Digital Half Toning - Ordered Dithering - MATLAB Code Bayer/ Ulichney December 23, 2016 Digital Half-toning is a technique to convert the gray scale / color image (in the range 0-255) to binary images (in the range 0-1) that is useful for printing (especially black and white printers). Gaussian noise tends to be represented by small values in the wavelet domain and can be removed by setting coefficients below a given threshold to zero (hard thresholding) or shrinking all coefficients toward zero by a given amount (soft thresholding). You can convert your RGB image to grayscale before PSNR calculation to solve this issue. /PSNR to calculate PSNR. program calculates performance metric RMSE, PSNR and Compression Ratio. calculate PSNR and MSE for image embeding and extraction. For color images with three RGB values per pixel, the definition of PSNR is the same except the MSE is the sum over all squared value differences divided by image size and by three. Cyber Investing Summit Recommended for you. Her code just uses one image, and she makes the common beginner mistake of thinking the standard deviation of gray levels in an image is all due to noise. The higher the PSNR, the better the quality of the compressed, or reconstructed image. 7335 Published with MATLAB® R2015b *Note: All matlab functions must be under same directory and make sure it is your working directory. @Amir Matin I guess Matlab code applies the process using a sliding window that convolves through the image and the final result is the average of this window.
