Abstract: An image processing method includes the following steps. A plurality of facial landmarks of a face frame are analyzed. A feature width is calculated according to the facial landmarks, and a head pose is analyzed according to the facial landmarks. The head pose is utilized to update the feature width to generate an updated width. A scale ratio of the updated width to an initial width is calculated. An object distance of a virtual camera is controlled according to the scale ratio. A two-dimensional image is captured from a virtual scene according to the object distance of the virtual camera.

Said humanized antibody also has high affinity and low immunogenicity. Said AXL antibody-drug conjugate has markable performance against tumors having high AXL expression.

Abstract: IMS gateway systems and methods are disclosed for providing budget control in an IMS network. IMS networks allow for media changes (e.g., audio to audio/video) during an IMS session. An IMS gateway system described herein receives a session control message (e.g., SIP INVITE message) responsive to the media change during the session. The IMS gateway system identifies media information for the new media in the session control message. The IMS gateway system generates a corresponding charging request message, and includes media information for the new media in the charging request message. The IMS gateway system then transmits the charging request message to an online charging system (OCS) to provide for charging of the session based on the new media for the session.

Abstract: IMS gateway systems and methods are disclosed for providing online charging for IMS sessions. An IMS gateway system described herein operates based on a state machine to provide charging triggers and IMS session control. For one charging trigger, the IMS gateway system transmits an initial credit control request message to an online charging system (OCS) responsive to receiving a session initiation message from a first subscriber of a session. For another charging trigger, the IMS gateway system transmits an update credit control request message to the OCS responsive to receiving a session acceptance message from a second subscriber of the session. For another charging trigger, the IMS gateway system transmits a termination credit control request message to the OCS responsive to receiving a session termination message. The IMS gateway system may trigger on other session control messages or charging messages from the OCS to provide online charging.

Abstract: Charging systems and associated methods are disclosed that provide correlation across network domains. The charging system includes a plurality of charging functions connected to one or both of an IMS domain and a packet bearer domain, such as a GPRS domain. A first one of the charging functions identifies the charging records for a particular session in the IMS domain based on a charging identifier. The first charging function then selects one of the charging functions on a per-session basis as a correlation charging function for the session, and forwards the identified charging records for the session in the IMS domain to the correlation charging function. A second one of the charging functions selects one of the charging functions on a per-session basis as the correlation charging function for the session, and also forwards charging records for the session in the packet bearer domain to the correlation charging function.

Abstract: IMS networks and methods are disclosed for charging for a session of a dual mode device that is transferred (seamless handover) from a first access network to a second access network. When a session is transferred between access networks, multiple charging identifiers (e.g., ICID) are assigned to the session. One or more network elements in the IMS network identify both an original ICID and a handover ICID for the session, and insert the original and handover ICID in a charging message that is transmitted to a charging system. The charging system then inserts the original ICID and the handover ICID in a CDR for the session. When the session ends, the charging system may use the original ICID and the handover ICID to correlate multiple CDRs for the session. Thus, even if CDRs for the same session have different ICIDs, the charging system is able to correlate the CDRs.

Abstract: IMS gateway systems and methods are disclosed for providing notification to an IMS subscriber. An IMS gateway system described herein includes a session manager and a notification database. The notification database stores a plurality of notification definitions for pre-session, mid-session, and/or post-session notifications. The session manager identifies a triggering event for a session of an IMS subscriber. A triggering event may be the initialization of a session, the account balance of the IMS subscriber running low, the termination of a session, or any other event as defined for the session manager. The session manager identifies at least one notification definition for the triggering event from the notification database, and provides notification (e.g.

Abstract: IMS gateway systems and methods are disclosed for providing online charging in an IMS network. A call control system of the IMS gateway system receives a message from a CSCF for a call session. The call control system identifies an OCS routing address from the message, and identifies a corresponding OCS routing address from the subscriber database. The call control system compares the OCS routing address from the message with the OCS routing address from the subscriber database. If the two OCS routing addresses match, then the call control system validates the OCS routing address from the message and/or the subscriber database, and transmits a charging request to the appropriate OCS based on the validated OCS routing address. If the two OCS routing addresses do not match, then the call control system transmits a charging request to the appropriate OCS based on the OCS routing address from the subscriber database.
