CS 194-26 Project 3 - Fun with Frequencies and Gradients!

By Jennifer Thakar

Part 1.1: Warmup

Original image, Sharpened (sigma = 10, alpha = 0.7)

Part 1.2: Hybrid Images

Hilfnero Hybrid (sigmas 1 and 3) Left to right: Hilfinger, Hilfinger low passed, DeNero, DeNero high passed, Hilfnero Frequency analysis for Hilfnero Left to right: Hilfinger, Hilfinger low passed, DeNero, DeNero high passed, Hilfnero Tenzinberg Hybrid (sigmas 4 and 12) Left to right: Tenzin, Walter White, Tenzinberg Failure Case: Derek/Nutmeg Hybrid (sigmas 3 and 10) Left to right: Nutmeg, Derek, Hybrid Failure most likely due to bad sigma values.

Part 1.3: Gaussian and Laplacian Stacks

All stacks show Gaussian on top and Laplacian on bottom Lincoln in Dalivision Stacks Mona Lisa Stacks Hilfnero Stacks

Part 1.4: Multiresolution Blending

Oraple Left to right: Apple, orange, multiresolution (7 levels) blended oraple Oraple Process Top to bottom: Gaussian stack of mask, Laplacian stack of apple, Laplacian stack of orange, combined Lapacian stack Soccer Globe Left to right: Soccer, globe, multiresolution (7 levels) blended image Sunset Eagle Left to right: Sunset, eagle, multiresolution (5 levels) blended image

Part 2.1: Toy Problem

Original Reconstructed

Part 2.2: Poisson Blending

Best Result: Sunset Eagle The poisson blending corrects for the different light under which the two photos where taken. Compare to multiresolution blending result above and direct paste below. The poisson blending works much better here. Pool Shark Penguins This is somewhat of a failure case, as it is actively snowing in the penguin picture, but not in the main picture.
