In this paper, we propose an embedding algorithm, of high visual quality, that can adaptively embed a binary message into an image. The binary message to be embedded is divided into two segments, each of which is then decomposed into n+1 or n types of sub-messages (where n ^(3) 3 enables each pixel to embed a sub-message), respectively, according to the desired embedding capacity. Embedding is done by leaving the pixel value unchanged or changing it into one of its n or n-1 neighboring values according to the type of the sub-message. From the results of this study, each pixel may not embed a fixed number of message bits and the adjustment of the pixel value is minimal, thus the image quality is significantly improved by adaptively decomposing the message into sub-messages and embedding them into the host image.
