The benefits of fewer colors include simpler screen displays and faster download times. Conclusions There are many computer processes that have been automated. For instance, as discussed above, the conversion of JPG to WBMP can be automated. However, for image display on a Palm VII there needs to be much human decision making in the process of creating the image. In this way, the scientist can better control what is displayed by the four colors.
Unsupervised classification does a reasonable job classifying the image into four colors.
However, a human needs to decide what the produced classes mean. When classifying an image and reducing the spatial resolution, information is lost in the process. There needs to be a human who decides what information is lost. For example, in this experiment, urban areas were combined with grassy areas. Also, wetlands were combined with forest.
