This paper presents high compression rate image coder based on Dictionary of Base Functions. Dictionary of Base Functions - BFB is a main part of proposed image compression. Proposed BFD has a ability to capture the characteristic of input images especially in high compression rates. Proposed image coder will be compared to the existing still image compression standard.
