ABSTRACT The third issues are compatibility and scalability. Different bitstreams, having multiple resolution versions of the image/video, are more desirable to different users with various computational capabilities. An efficient technique for hierarchical image coding is proposed, which divides an image into its multiple resolution versions with minimum hardware cost. Since the proposed techn...

This paper proposes a color image coding algorithm based on shape-adaptive all phase biorthogonal transform (SA-APBT). This algorithm is implemented through four procedures: color space conversion, image segmentation, shape coding, and texture coding. Region-of-interest (ROI) and background area are obtained by image segmentation. Shape coding uses chain code. The texture coding of the ROI is p...

This comparison paper scrutinizes image compression using Block Truncation Coding. Many algorithms were selected likely the original Block Truncation coding, Absolute Moment Block Truncation Coding, a comparison survey was executed. These above techniques are divided image into non overlapping blocks. They distinguish in the direction of choosing the quantization level in order to remove redund...
