The conception of universal combinatorial coding is proposed. Relations exist more or less in many coding methods. It means that a kind of universal coding method is objectively existent. It can be a bridge connecting many coding methods. Universal combinatorial coding is lossless and it is based on the combinatorics theory. The combinational and exhaustive(More)
The parallel computing method of max ordinal number in universal combinatorics coding based on GPU is advanced in this paper. The core of universal combinatorics coding computing is ordinal number computing while the calculation of ordinal number depends on the value of max ordinal number. The calculation of max ordinal number is divided into two parts,(More)
Combinatorial encryption algorithm is advanced. Combinatorial encryption method makes use of the variety of ordinal in universal combination code. Firstly, the theory of universal combinatorial coding is expatiated. Secondly, researches are done in combinatorial encryption characteristic, key generating method, encryption and decryption algorithms. At last,(More)
Changes in the appearance of retinal blood vessels are an important indicator for various ophthalmologic and cardiovascular diseases, including diabetes, hypertension, arteriosclerosis, and choroidal neovascularization. Vessel segmentation from retinal images is very challenging because of low blood vessel contrast, intricate vessel topology, and the(More)
Universal combinatorics coding is a new kind of coding method and whole ordinal plays an important role in universal combinatorics coding. Whole ordinal GPU parallel algorithm is proposed in this paper. Whole ordinal computing is implemented by combining the advantage of GPU in aspect of complicated and vast parallel computing with CPU technology, and(More)
