Final Project

Computer Vision

Topics 1. Stereo Matching Improvement

- 수업시간에 배운 방식으로 최적의 성능 내기 + Dynamic Programming 추가

- 기타 새로운 문제 해결 방식 추가: Occlusion, Hole filling, Boundary noise, thin object, non-textured region

Dataset: http://vision.middlebury.edu/stereo/data/scenes2014/

2. Panorama using Homography

- 신뢰도 높고 더 많은 Matching point pair 찾기: ex) SIFT, etc

- Homography 계산 정확도 향상, tone mapping

Dataset: use your own pictures (more than 10 images)

3. Change Detection

- 개선된 Detection Result

- 노이즈 제거, Clutter 제거, Morphological post procession

Dataset: http://jacarini.dinf.usherbrooke.ca/static/dataset/badWeather/skating.zip

4. CNN based Classification using Tensorflow and MNIST

- 개선된 Classification Result on distorted (affine, occlusion, noisy) test images

제출 내용: Commented Source Code, Result Images, Report Document
