A new vector coding for natural image, which has a compressive algorithm, is presented and the image features showed in this method are described. The pixel-value-boundary contours on RGB or YCrCb planes of natural images are expressed by function approximation and then their contour shapes are predicted from similar contours in the decoder side. The proposed vector coding method has two main merits: one is to meet the demands of expansion and reduction of images, the other is to suit content distribution because the image quality can be kept even under the repetition of editing due to representation of function approximation. To put vector coding for natural images to practical use, we compress the data by using the characteristics in three-dimensional representation of images.
