Existing compression schemes usually scan an image by a fixed way.However,each image has its own characteristics,which makes it difficult to obtain a good coding performance with a fixed scanning manner.To solve this problem,an adaptive scanning-based compression method is proposed.Firstly,the wavelet transform is performed.Then the scanning order among the subbands is determined by the content of the image.Secondly,for the scanning of a subband,in order to preserving the texture information as much as poss...
