17 results about "Group code" patented technology

In coding theory, group codes are a type of code. Group codes consist of n linear block codes which are subgroups of Gⁿ, where G is a finite Abelian group. A systematic group code C is a code over Gⁿ of order |G|ᵏ defined by n-k homomorphisms which determine the parity check bits. The remaining k bits are the information bits themselves.

A bulletin board interaction pickup method and system based on block coding

The application relates to the technical field of graphics processing, and particularly discloses a bulletin board interaction pickup method and system based on grouping coding. In view of the problem that a traditional bulletin board pickup scheme needs to repeatedly render or additionally use 32-bit textures, resulting in large GPU performance loss and poor real-time performance in a massive bulletin board scene, the application first continuously divides bulletin boards B1 to Bn into at most 256 groups, and batch renders the bulletin boards to a texture T0, wherein the R, G and B channels store colors, and the A channel stores group IDs; then the dynamic bulletin board is redrawn, the A channel of a T0 point selected pixel is sampled to obtain a group ID, the absolute bulletin board ID is calculated by combining the relative number, the position information is called according to the absolute ID, the position information is rendered to 1x1 pixels and is subjected to a depth test to retain the nearest ID, and finally, the CPU reads and decodes the ID to complete the pickup. The method does not need additional textures or repeated rendering, greatly reduces the GPU load, improves the pickup accuracy and real-time performance, and adapts to the interaction demand of massive bulletin boards in a BIM scene.
