Abstract
This paper presents an approach to image compression for solid color pictures using
segmentation and solid color image. An approch is presented that targets the solid color regions
in the image as the source of redundancy and attempts to minimize this redundancy. The approch
works by identifying regions in the image having pixels with similar color characteristics
with respect to the specified tolerance level. To identify the solid color regions in the image,
breadth-first traversal algorithm is used. The abbreviated form of these regions with necessary
information is stored in the encoded image using recursive boundary splitting and the image is
decoded using polynomial interpolation. In order to measure the quality of the image we have
incorporated stretch factor. The results procured have been very satisfying and encouraging
as it clearly has a sizeable lead over other conventionally used compression techniques.
