Near real time Internet access of prepaid call history and replenishment data is provided via an Internet browser separate from the prepaid device to a user (e.g., the subscriber), allowing a subscriber to access call history and / or replenishment information nearly in real time (e.g., within a minute of the expense / credit) without requiring assistance from a customer service representative. A web based prepaid report page retrieves call history and / or replenishment information from the subscriber's service provider, and displays the same through a web browser for review by the subscriber. The requested call history and / or replenishment information may be bounded by date, date and time, or even within specific time range(s) within each day in a given range of days. The web based prepaid report page may also link the user to a replenishment application for the subscriber, to assist the subscriber in replenishing their account after having reviewed their call history and prepaid account status in near real time. The call history and account balance information is preferably updated in near real time after the completion of a call, which is then accessed by the web based prepaid report page. Substantially immediately after a prepaid call is ended, the web based prepaid reporting application formulates a Call Detail Record (CDR) and sends it over a TCP / IP link to the web based prepaid reporting application, which stores the CDR in a local database. Then, a user may access this CDR / RR information in near real time, after appropriate log-in with, e.g., a user ID of the subscriber (e.g., MIN number based), and perhaps a password. Once the requested information is entered, the web based prepaid reporting application queries its local database, formats an appropriate response to the user's request, and presents the call history and / or replenishment information to the web browser of the user.

A method for human face detection that detects faces independently of their particular poses and simultaneously estimates those poses. Our method exhibits an immunity to variations in skin color, eyeglasses, facial hair, lighting, scale and facial expressions, and others. In operation, we train a convolutional neural network to map face images to points on a face manifold, and non-face images to points far away from that manifold, wherein that manifold is parameterized by facial pose. Conceptually, we view a pose parameter as a latent variable, which may be inferred through an energy-minimization process. To train systems based upon our inventive method, we derive a new type of discriminative loss function that is tailored to such detection tasks. Our method enables a multi-view detector that can detect faces in a variety of poses, for example, looking left or right (yaw axis), up or down (pitch axis), or tilting left or right (roll axis). Systems employing our method are highly-reliable, run at near real time (5 frames per second on conventional hardware), and is robust against variations in yaw (±90°), roll(±45°), and pitch(±60°).

The invention provides a scalable video coding method where a region of interest has transmission priority. In the method, the region of interest is treated with default setting or optionally chosen by a user at a receiving terminal during coding. The bit stream of an enhancement layer is treated in different manners according to the fact that whether an instruction is received from the region of interest (ROI) when the instruction is sent. If the instruction from the ROI is not received, the encoded bit stream is packed according to a preset order and an obtained channel bandwidth; if the instruction from the ROI is received, a coding and recoding module recodes after coding according to the position and the size of the region of interest and has the transmission priority so as to ensure that the region of interest of the user at the receiving terminal is more clear to improve the subjective quality of the video. When an encoded video streaming media is transmitted or a quasi-real-time video is transmitted by the scalable video coding method of the invention, the user at the receiving terminal can optionally choose the region of interest and the video effect of the region of interest can be greatly improved, therefore, not only precious transmission bandwidth resources is saved, but also the subjective quality of the video is improved.
