![]() ![]() This is because Laplacian pyramid keeps blurring the mask so that at the uppermost layer the mask results in the algorithm taking an average of the target and source images, and the pixels values of the fireworks remains unmodified when blended into the background because the mask is sharp at lower levels. It is observed that Laplacian pyramid blending achieved similar result on the second example, but is different on the first, that the overall image became darker but the color of the fireworks are better preserved. (Pyramids have depth 6 Gaussian pyramid uses 4px standard deviation, Laplacian pyramids 2px) (Pyramids have depth 20 Gaussian pyramid uses 6px standard deviation, Laplacian pyramids 2px) Blend keisatsu's notice via Laplacian pyramid The Laplacian pyramid image blending technique was introduced in Project 2 Bells and Whistles section, and comparison to Poisson image blending is made with the monument and keisatsu's notice examples. Original picture: Raja Ampat Flattened Raja Ampat Laplacian Pyramid Blending \īelow is a result from this technique with \(\alpha = 8\). Let \(v_i\) denote the pixel values that would be copied to location \(i\) in the background for each \(i\in M\) after optimization, then \(v\) is the solution to When outputting in CMYK, the gray image is calculated using a built-in color-to-grayscale conversion in InDesign. ![]() It allows you to convert placed color photos to grayscale without modifying the original color image. Let \(i\in\times\) denote the coordinates within the background image, \(t_i\) and \(s_i\) denote the pixel values of the background and aligned source image, and \(M\subset \times\) denote the mask, so that the goal is to blend pixel values \(s_i\) to location \(i\) in the background image for each \(i\in M\). Color2Gray version 2.0.3 is now available and supports InDesign CS6.
