    • This invention is a method applicable to an image processing device, which includes the steps of providing a preprocess module for extracting a high-frequency portion of an image inputted into the device, extracting a gradient of the image and decomposing the image into plane and edge regions according to a predetermined fixed threshold, and providing a composite up-scaling module for executing the magnification processes on the image and the high-frequency portion thereof respectively, wherein the magnification process of plane regions of the image and the high-frequency portion is based on a simple interpolation while the edge regions of the image and the high-frequency portion is based on both a smart interpolation and the simple interpolation. The magnification results of the image and the high-frequency portion are then processed by a fusion process, so as to output an image having sharp but not blocky edges, rich details and strong contrast.
    • 本发明是适用于图像处理装置的方法,其包括以下步骤:提供用于提取输入到装置中的图像的高频部分的预处理模块,提取图像的梯度并将图像分解成平面和边缘 区域,并且提供用于分别对图像和高频部分执行放大处理的复合上调模块,其中图像和高频部分的平面区域的放大处理是 基于简单的插值,而图像和高频部分的边缘区域基于智能插值和简单插值。 然后通过融合处理处理图像和高频部分的放大结果,以便输出具有锐利但不块状边缘的图像,丰富的细节和强烈的对比度。

    • A method for detecting a facial expression and repairing a smile face of a portrait photo includes the steps of: detecting a location and a range of a mouth region in an inputted portrait photo; capturing a patch in the mouth region and a predetermined peripheral range thereof; executing a comparison process to a smile state or a stiff state of the mouth region in the patch by a mouth state classifier; executing a calculation process to a repaired region of the mouth region when the mouth region is determined to be in the stiff state, in order to calculate a location of a plurality of feature points in the repaired region of the mouth region; and executing an image warping process to the location of the feature points and adjacent pixels thereof, for generating a portrait photo showing a smile state.
    • 用于检测人脸照片的脸部表情和修复微笑脸部的方法包括以下步骤:检测所输入的肖像照片中的口部区域的位置和范围; 在嘴区域和其预定的周边范围内捕获贴片; 通过嘴状态分类器对贴片中的口部区域的微笑状态或僵硬状态执行比较处理; 为了计算口部区域的修复区域中的多个特征点的位置,对嘴部区域的判定为处于刚性状态的口部区域进行计算处理, 以及对其特征点和相邻像素的位置执行图像变形处理,以产生显示微笑状态的肖像照片。

    • A WTRU configured to receive a multicast, a unicast or mixed signal. A multimedia signal may be a Multimedia Broadcast Multicast Signal (MBMS). The WTRU switches between an MBMS and a mixed signal and determines optimal time to switch between the MBMS and mixed signal. The WTRU switches between receiving the MBMS and mixed signal in an adaptive or semi-static pattern. A flat broadcast channel (BCH) structure in an MBMS dedicated cell is provided, eliminating need for a dedicated broadcast channel (D-BCH). An MBMS-dedicated cell uses a single paging channel for both paging-indicators and paging-record-blocks. A system information broadcast indicates flexible resource usage and paging-record-block limits. Tracking area (TA)/cell association is provided for an MBMS-dedicated cell and geographically co-located non-MBMS-dedicated cells. MBMS-dedicated cell system information is broadcast to regulate WTRU operation while receiving MBMS within said cell. Generic Access Profile (GAP) definitions is part of system information.
    • WTRU被配置为接收多播,单播或混合信号。 多媒体信号可以是多媒体广播多播信号(MBMS)。 WTRU在MBMS和混合信号之间切换,并且确定在MBMS和混合信号之间切换的最佳时间。 WTRU在以自适应或半静态模式接收MBMS和混合信号之间切换。 提供MBMS专用小区中的平坦广播信道(BCH)结构,消除对专用广播信道(D-BCH)的需要。 MBMS专用小区对寻呼指示符和寻呼记录块使用单个寻呼信道。 系统信息广播指示灵活的资源使用和寻呼记录块限制。 针对MBMS专用小区和地理上位于非MBMS专用小区的跟踪区域(TA)/小区关联提供。 广播MBMS专用小区系统信息以在所述小区内接收MBMS时调节WTRU操作。 通用访问配置文件(GAP)定义是系统信息的一部分。
