This project aimed at retrieving and localizing objects of interest from pictures taken by a smart phone. We have clean poster images in the dataset. Given an query image taken by a camera or a smartphone, we want to find the corresponding images in the dataset based on the content of the image. The technique can be used for product search, content based information retrieval/indexing.

Problems we want to solve
Problem 1. Feature representation local patterns are not efficient in discriminating images which have similar local appearance.
Problem 2. Same local features have different importance in different images. Figure 4 shows an example. The descriptor in the wild is less important than the grass descriptor in a book cover.
