Fun with frequencies

Castro Cabrera, Ramses


1. Description of the project

The objective of this project is to generate different images "playing" with the frequencies, specifically with the low-frequencies and high-frequencies in order to get a new image or a combination of multiple images. This project looks to make the student understand the importance of the different frequencies in the image processing.

Part 0: Warmup

Alebrije



Radius: 2
Amount:3


Orangutan



Radius: 3
Amount:1


Part 1: Hybrid Images

Chewbacca & Harry


Chewbacca taken from this page (Harry came from nowhere, I already had it)

Transition 1


After this process, the choice of the best image was made

cutoff1 base: 1
cutoff2 base: 0.2
(x2 for each iteration)

figure 2: cutoff1=2; cutoff2=0.4
figure 3: cutoff1=4; cutoff2=0.8
(I chosed figure 3)
figure 4: cutoff1=8; cutoff2=1.6


Transition 2


After this process, what was done is to change de values of cutoff1 and cutoff2
base so it could change with the iteration

cutoff1 base: 0.5
cutoff2 base: 0.3

figure2: cutoff1=1; cutoff2=0.6
figure3: cutoff1=2; cutoff2=1.2

Chosen image:


After this process, it was made the frequency analysis

Harry

Chewbacca

Harry low F

Chewbacca high F

"Churry"



Part 2: Gaussian and Laplacian Stacks

Lincoln & Gala


Transition Lincoln & Gala


After this process, the choice of the best image was made

cutoff1 base: 1
cutoff2 base: 0.3
(x2 for each iteration)




"Churry"


Transition Churry



cutoff1 base: 0.5
cutoff2 base: 0.4
(x2 for each iteration)

Part 3: Multiresolution Blending

The orple (In fact three)




Dog "Malt-naucher"


left: My dog
right: A dog from this page

Irregular mask

Dog "Thug baby"



Dog "Gatoso"



Personal images

Dog "Assassin"



Dog "Stormtrooper"



For this part I've found difficult to resize the image to a convenient size, using the allingn tool makes easy to put in position an image but doesn't solve the problem of the size so I've had to "play" with the reference point of each image to meke them fit
