Machu Picchu, Perú

1. Image Representation and Visualization

## Digital Image

--

## Fourier Transform

-
DFT of original image ------------ DFT of the Roberts kernel

Multiplication of both DFTs -------- Inverse-DFT

2. Image Enhancement

## Contrast Enhancement

--
Original image ---------------- Logarithmic enhanced

## Edge Detection

##
Left: Original, Right: Sobel operator

Left: Prewitt operator, Right: Isotropic operator

## Pseudo Color

--
--
Rainbow colortable ------------- SApseudo colortable

## Median Filter

-
Original image --------------- Shot Noisy image at 10%

-
Median Filtered: Left: 3x3 window, Right: 5x5 window

## Image Sharpening

Top Left: Original image
Top Right: Laplacian filtered image
Bottom Left: Sharpened image, Adding the original with the Laplacian
Bottom Right: Frequency response of the Laplacian filter.

## Magnifying (interpolation)

3. Image Restoration

## Wiener Filter

-
Left: blurred byte type image, Right: its spectrum

-
Left: frequency response of the Wiener filter,
Right: Result of the Wiener filter

4. Image Analysis

## Image Segmentation: Threshold

--
Original image ---------------- Threshold: 118

## Area Measurement and Display

Random pseudocolor: labeled image

Intensity is proportional to area of each connected regions

## Pattern Classification

Original binary image

Classified image
