Abstract
Decomposing a computer display image into different layer types and associated masks based on the unique nature of the image is disclosed. These types include text, objects, background and pictures. A set of image masks is used to uniquely identify different layer types within an image, where each layer type includes none, some or all of the pixels of the original image. Each layer of the image is processed prior to transmission (i.e. compressed) using a method appropriate for the characteristics of that layer.
