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
