Computer Vision Study and Research Notebooks

This is a self reference repository for all my trial solutions for computer vision problems.

Most of the notebooks in this repository are not complete or left abandoned due to the lack of any further success in what I was trying to get to.

Some working ones

Algorithms

Process of Harris Corner Detection Algorithm.ipynb

Harris corner detector

Principal Component Analysis from scratch for 2 dimensional dataset

Principal Component Analysis from scratch for 3 dimensional dataset

Applications

Algorithm for detecting and extracting number plates from images of cars.ipynb

Find subimage through template matching

Various ways of converting an image to grayscale.ipynb

color quantization using kmeans

haars face detection

median cut color quantization.ipynb
