The redundancy in digital image representation can be classified into two categries: local and global. In this paper, we propose a new lossles binary image compression processing scheme which increases local redundancy for more compression efficiency. The algorithm consists of reordering rows and columns of image data for assembling data that has a same value: '0' or '1' merging each matrix ele...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

This paper proposes adaptive Boolean lters for realizing the prediction stage in lossless compression of greylevel images. The adaptation of Boolean lters is performed using local information about the presence and orientation of edges (high local amplitude variations) of the pixels inside the prediction mask. It is shown that adaptive predictors improve the performance of optimal Boolean predi...
