Wedgelet-based coding concept
Wedgelet-based coding in conjunction with the usage of coding blocks of varying size is rendered more efficient by the usage of a variable length coded syntax element having a prefix and a suffix, wherein the size of the suffix is dependent on the prefix and the size of the current coding block. By this measure, it is feasible to efficiently adapt the length of the variable-length coded syntax element which controls the bi-partitioning of the current coding block to the actual needs, namely the size, of the current coding block, and the variability of the bi-partitioning by varying the wedglet separation line, respectively. The greater the current coding block is, the longer the variable-length coded syntax element may be. This length dependency may even be sufficiently effective in terms of coding efficiency so that the variable length coded syntax element may be coded without context-adaptive entropy coding, but directly or using fixed-equal-probability binary entropy coding. |

An approach is provided for securing a network-accessible site such as a bank, financial institution, or a user's home system. A request is received from a user of the network-accessible site. While the request is from a user, the system further verifies that the user is the authorized user and not an imposter, such as a hacker. To this end, the approach transmits a state inquiry to a wearable device registered to the user. The current state of the user is received from the wearable device, such as whether the user is sitting, standing, walking, sleeping, etc. If the system determines that the current user state allows the action to be performed at the site by the user, then the action is performed. Likewise, if the system determines that the current user state disallows the action, then the system inhibits, or otherwise prevents, the action from being performed. |
