  1. Derived a New Algorithm for Optimizing FIR Decision Feedback Equalizer Giving Low Complexity and Better Performance Fast Optimization of FIR Decision Feedback Equalizer

  2. Syllable-based One-pass Search t Acoustic Models Syllable Lattice P(w1)P(w2 |w1)...... P(w1)P(w2 |w1)...... w1 w2 Word Graph w1 w2 Language Models Lexicon • Finding the Optimal Sentence from an Unknown Utterance Using 3 Knowledge Sources:Acoustic Models, Lexicon and Language Model • Based on a Lattice of Syllable Candidates

  3. unknown known verified u/k/v: unknown, known, or verified c/e/x: correct, error, or don’t care (v,c) (k,c) (u,x) (k,e) (v,e) slot lost Random Tests Rl, Rm slot i slot i User System slot j (error) Random Select j no misunderstanding Statistical Formulation and Analysis for Spoken Dialogue Systems • A Spoken Dialogue System Formulated as a Process of Transmitting a set of Semantic Slots from the User to the System • Finite State Machine Representation • Channel Model for Slot Transmission • slot lost rate Rl : desired slots lost • slot misunderstanding rate Rm : wrong slots received causing misunderstanding

  4. 建立一個「網路音樂會」的架構： 一、合成音效 二、虛擬電子琴 三、CSocket網路通訊（Server-Client） 四、網路與音樂控制的結合 網路音樂會雛型之設計與實作

  5. Flashlight Homogenous white and bright Low variance Unusual Intra-coded MB in B frame Unusual consecutive two abrupt scene change Flashlight detection

  6. This project aims to develop a novel human-computer interface system controlled by eye movements With an infrared optical sensor array, position of pupil can be detected and used for cursor control (ROC patent) A software system is built for routine PC window environments Optical Mouse by Eye Movements

  7. Principles of Detection (a) (b) (a)IROG方式之紅外線光打在眼球的位置， (b)輸出電流與眼球運動角度之轉換曲線關係

  8. Cursor Control 視動滑鼠不反應區之電腦畫面︰中間灰色框框為不反應區，眼球可在中間注視休息而不影響電腦游標之位置。正常操作時，此框框會消失隱藏於於幕後，以免妨礙使用者選項。

  9. Scalable – The ability of decoding visual information at varying rates from a single compressed bitstream. Scalable Codec Football: 1.5M bps, 16 fps S=3 (352x288) S=1 (88x72) S=0 (44x36) S=2 (176x144)

  10. Error – Resilience Video The Result Without/With Error-Resilience Technique

  11. construct panoramic images automatically in real-time from capturing a scene over 360 degrees static stripe of MPEG-4, museum, house, travel, etc. VideoVR

  12. protect the ownership of images and their associated software resist various attacks: compression, pixel-shifting, cropping, etc. VideoVR + Watermark

  13. Computational ALU MAC SFT CMP Data Movement Program Flow Special instructions Total 92 instructions ! Instruction Types

  14. CMAC/CMUL, SQS Complex MAC/MUL I*I+Q*Q ACS Dual Add-Compare-Select operation TRCBK Traceback FIR2 Two FIR operations in one cycle Special Instructions

  15. DSP Simulator Interface • Step/Free Running • Run # clocks • Run to PC=# • Monitor Register • Monitor Memory • Interrupt Generation
