Abstract - DNA microarray images are experiments that allow the identification of the function and regulation of a large number of genes in a single experiment. These micrarray experiments consist of a pair (green and red channel) of 16 bits per pixel grayscale images. This paper addressed a lossless method to compress these kind of images, using a mixture of finite-context models and arithmetic coding. We use a 3D context configuration, expectation-based bitplane coding and also a typical image context template in the mixture. We conclude that using a mixture of finite-context models we are able to improve the compression results.
