Description: CELP
The most common Speech coding scheme is Code-Excited Linear Predictive (CELP) coding, which is used for example in the GSM standard. In CELP, the modelling is divided in two stages, a linear predictive stage that models the spectral envelope and code-book based model of the residual of the linear predictive model.

Description: 这份报告概述了项目修改语音信号与各种不同的效果。实现的效果是一个呼应,相移和残余阈值剪裁。的分析过程和技术参与实施这些技术也提供了一个洞察整个项目选择背后的原因。这份报告将细分一个语音信号的分解步骤,将段到频域,估计谱包络,操纵信号以不同的方式,然后回到回放的时间域。附录中提供一份项目以及示例输出结果。还提到可能的扩展项目,可能会增强其功能和团队的建议进行这些增强功能。-This report outlines a project to modify a speech signal with various different effects. The effects implemented were an echo, a phase shift and a residual threshold clipping. An analysis of the process and techniques involved in implementing these techniques is also offered with an insight into the reasons behind the choices made throughout the project. This report will break down the steps of segmenting a speech signal, transferring segments into the frequency domain, estimating the spectral envelope, manipulating the signal in various ways, then returned to the time domain for playback. A copy of the project is provided in the appendix as well as sample output results. Also mentioned are possible expansions on the project that could enhance its functionality and the team’s recommendations in proceeding with these enhancements. Platform: |

Description: 《Saliency Detection: A Spectral Residual Approach》是上交高材生侯晓迪在07年的CVPR上发表的一篇论文，这篇文章提出了一个图像视觉显著性的简单计算模型，这个模型和Irri提出的模型是两个截然不同的模型，Irri模型对于图像视觉显著性主要关注整幅图片突出的部分，通过各种特征的融合提取显著性图，而Hou的这个模型一上来关注的点就不在一张图片里突出的地方，而是背景，观察是否大部分图片的背景在某个空间上都满足什么变化，最后剔除背景，自然就只剩下图片突出的部分了-" Saliency Detection: A Spectral Residual Approach" is turned on in the top students HOU Xiao Di 07 years CVPR paper published, this article presents a significant visual image of a simple calculation model, the model and the model proposed is two Irri distinct model, Irri model for the image saliency focused on the entire picture projecting portion extracted by the integration of the various features saliency map, and Hou this model up a point of interest in a picture is not prominent in place, but the background to observe whether the majority of the background image on a space to meet any changes, and finally removing the background, naturally, only the image projecting part Platform: |

Description: 首先对输入音频PCM信号进行时频分析，决定MDCT的长度，即加窗，然后进行MDCT变换；同时对原始音频信号要进行FFT分析。两种变换的频谱系输入给心理声学模型单元，MDCT系数用于噪声掩蔽计算，H可结果用于音调掩蔽特性计算，共同构造总的掩蔽曲线。然后根据MDCT系数及掩蔽曲线，对频谱系数进行线性预测分析用LPC(Linear Prediction Coefficience，线性预测系数)表示频谱包络，即基底曲线(Floor Curve)；或通过线性分段逼近方式获得基底曲线。从MDCT系数中去掉频谱包络则得到白化的残差频谱(Residue)，由于残差频谱波动范围明显变小，从而降低量化误差。之后可以选择是否采用声道耦合(Channel Coupling)技术进一步降低冗余度，耦合主要是将左右声道数据从直角坐标映射到平方极坐标；最后对白化的残差信号有效地以矢量量化表示。最后将要传输的各种信息数据按Vorbis定义的包格式组装，形成Vorbis压缩码流。-First, the input audio PCM signal time-frequency analysis to determine the length of the MDCT, that windowing, then MDCT transform while the original audio signal to FFT analysis. Two Transformations spectral line input to the psychoacoustic model unit, MDCT coefficients used to calculate the noise masking, H can be used to tone masking characteristic calculation result, the overall structure of the common masking curve. Then according to the MDCT coefficient and the masking curve, spectrum analysis using linear prediction coefficients LPC (Linear Prediction Coefficience, linear prediction coefficients) represent the spectral envelope, ie the base curve (Floor Curve) or approaching the base curve obtained by linear segments. Removed the MDCT coefficients in the spectral envelope of the residual spectrum obtained albino (Residue), since the fluctuation range of the residual spectrum significantly smaller, thereby reducing the quantization error. Then you can choose whether to use cha Platform: |
