摘要： An exemplar dictionary is built from example image blocks for determining predictor blocks for encoding and decoding images. The exemplar dictionary comprises a hierarchical organization of example image blocks. The hierarchical organization of image blocks is obtained by clustering a set of example image blocks, for example, based on k-means clustering. Performance of clustering is improved by transforming feature vectors representing the image blocks to fewer dimensions. Principal component analysis is used for determining feature vectors with fewer dimensions. The clustering performed at higher levels of the hierarchy uses fewer dimensions of feature vectors compared to lower levels of hierarchy. Performance of clustering is improved by processing only a sample of the image blocks of a cluster. The clustering performed at higher levels of the hierarchy uses lower sampling rates as compared to lower levels of hierarchy.

摘要： The invention provides an apparatus and a method for improving the control of access by a terminal device in a WLAN environment having an access point for determining whether the device utilizes an IEEE 802.1x protocol by the access point communicating to the device, a packet, whereby if the devices utilizes a IEEE 802.1x protocol the device appropriately responds and otherwise the access point determines that the terminal device protocol does not employ a IEEE 802.1x protocol and selects an authentication mechanism compatible with the terminal device. If the device is not an IEEE 802.1x client, an IP packet filtering is configured to redirect a user HTTP request to a local server, and when the HTTP requests are thereby redirected, the HTTP server presents the terminal device with information specifically related to the browser based authentication.

摘要： A wireless LAN provides access to a mobile terminal (MT) utilizing beacon frames to broadcast access point (AP) service specific information. The MT listens to the beacon frames and compares the broadcast service(s) and service parameters to a predetermined service profile stored in the MT. When the services offered by an AP matches the services designated in the stored service profile, the MT associates with that particular AP.
