Abstract

There exist many lossy image compression techniques, some of which are based on dimensionality reduction. In this paper, a method for lossy image compression is introduced which utilizes the dimensionality reduction technique known as Random Projection. Random Projection has proven itself as an effective technique for reducing the dimensionality of data, particularly when dimensionality d is moderately high (e.g., d
