    • A texture-based text localization system proceeds directly in the compressed domain for DCT compressed JPEG images or MPEG videos. The DCT coefficient values in JPEG images and MPEG videos, which capture the directionality and periodicity of local image blocks, are used as texture feature measures to classify text areas. Each unit block in the compressed images is classified as either text or nontext. In addition, post-processing in both the compressed domain and the reconstructed candidate text areas can be used to refine the results. For video frames that contain text, the displacement of text between two consecutive frames is estimated which gives the velocity of the moving text. This temporal displacement information is also used to further refine the localization results. The text is then processed to provide content or speech output.
    • 基于纹理的文本定位系统直接在DCT压缩JPEG图像或MPEG视频的压缩域中进行。 JPEG图像和MPEG视频中捕获局部图像块的方向性和周期性的DCT系数值被用作对文本区域进行分类的纹理特征量度。 压缩图像中的每个单位块被分类为文本或非文本。 另外,可以使用压缩域和重建的候选文本区域中的后处理来优化结果。 对于包含文本的视频帧,估计两个连续帧之间的文本位移给出了移动文本的速度。 该时间位移信息也用于进一步改善定位结果。 然后处理文本以提供内容或语音输出。

    • A method of interface communication between entities in soft switch system in NGN, and a method and apparatus for Gateway Control Protocol (GCP) message transmission are disclosed, so that H.248 messages can be transmitted between Media Gateway Controller and Media Gateway over MTP3B/ATM, hence full advantages of resources are taken in existing optical fiber networks and E1/T1 networks, so as to improve the networking flexibility and reduce the cost. The internal data transmission mechanism between MTP3B protocol layer and H.248 protocol layer is established via an M3H adaptation layer; load sharing between H.248 processing modules is enabled by establishing mapping between H.248 links and MTP3B signaling points; the adaptation relationship between MTP3B layer and H.248 layer is implemented by configuring and maintaining logic relationship between table of LinkSets, H.248-MTP3B mapping table, and table of H.248 processing modules, thus implementing the mechanism of bearing H.248 messages over MTP3B.

    • A method for protecting a Digital Subscriber Line Access Multiplexer (DSLAM) includes: capturing specific protocol packets at an XDSL port by hardware of an XDSL single service board; and sending the captured specific protocol packets to a CPU of the XDSL single service board; determining whether the traffic amount of the specific protocol packets in a time unit exceeds a predefined threshold, if the traffic amount does not exceed the predefined threshold, submitting the specific protocol packets to a CPU of the host; otherwise stopping submitting the specific protocol packets to the CPU of the host. The method and the XDSL single service board provided by embodiments of the present invention need not manually set Media Access Control (MAC) address or maximum MAC address learning number for each XDSL port, which cuts down the maintenance workload, and on the other hand, reduces the loss of important protocol packets and lowers the load of the CPU.
