Abstract
We show a simple, yet effective, method for storing images, such that retrieval of nearby images is both fast and accurate. The main ingredients are discrete Fourier transforms to extract low frequency components, principal components analysis (PCA) for further compression, and storage in k-D trees. We illustrate the quality of results on the MNIST digit suite and also apply it to chromosome segments.
