Abstract - In this paper we present a rate-distortion study on microarray image compression. We evaluate two image coding standards (JBIG and JPEG2000), a method based on bitplane decomposition, and a method recently proposed based on binary-tree decomposition. According to the results obtained JPEG2000 attains the worse compression results particularly for higher bitrates. On the other hand, the method based on binary-tree decomposition outperformed all the other compression methods in terms of L2-norm and L∞-norm. The results attained for the binary-tree decomposition method can be explained due to its nature, consisting on coding each node of the tree with the goal of minimizing the L∞ error.
