This is my final year project associated with The Husky Lab under the supervison of Prof.James Cheng. In this project, I built an Image Retrieval System using LoSHa, a A general framework for scalable Locality Sensitive Hashing (LSH). This research project shows more salability and a 15% increase in speed when compared to OpenCV FLANN.
Here I excerpt some of the main concepts of the project. What I aim to do is to look for the original piece of image within a directory full of images given part of the image that could have been altered and cropped.
- Husky & LoSHa
Overview & Results
There are three steps to complete the process:
- Create Image Binary
- Run nearest neighbor search (NNS)
- Match image
With the contrast and lightening altered duck.jpg, we can correctly find the original image within the directory.
