A few projects, done as part of the course work for Digital Image Processing, IIIT-D.

Digital-Image-Processing

Assignment 1

• Q3 --> Bilinear Interpolation
• Q4 --> Geometric Transformation using bilinear interpolation
• Q5 --> Restoring an unregistered image using a reference and manually providing pivot points.

Assignment 2

• Q3 --> Histogram Equalization
• Q4 --> Histogram Matching
• Q5 --> Spatial Convolution

Assignment 3

• Q1 --> Filtering in Fourier Domain (Butterworth example for demo)
• Q3 --> Filtering in Fourier Domain when filter in spatial domain (assuming top-left point as origin).
• Q4 --> Observing a noisy image in Fourier Domain, suppressing noisy frequencies to restore the corrupt image.

Assignment 4

• Q1 --> Attempting to restore an image using Constrained Least Squares Filter.
• Q3 --> Histogram Equalization of a color RGB image by converting it to the HSI space.
