tf–idf, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.[1]:8 It is often used as a weighting factor in information retrieval and text mining. The tf-idf value increases proportionally to the number of times a word appears in the document, but is offset by the frequency of the word in the corpus, which helps to control for the fact that some words are generally more common than others. Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document s relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields including text summarization and classification. One of the simplest ranking functions is computed by summing the tf–idf for each query term many more sophisticated ranking functions are variants of this simple model.

说明：  多媒体播放器是一个多媒体应用，能够播放声音、视频剪辑和图形图像。 该应用程序还可以录制和播放高通PureVoice音频剪辑。 该播放器包括标准的MediaPlayer控制，如播放，快进，快退，停止，暂停和录制。 多媒体播放器支持各种各样的音频，视频和图形格式， 包括MPEG-3，MIDI，BREW的压缩图像（BCI），位图（BMP）和分组模式数据（PMD）。 (MediaPlayer is a multimedia application capable of playing sound and video clips, and displaying still graphic images. The application can also record and play back QUALCOMM PureVoice (QCP® ) audio clips if you have the appropriate CMX® DLLs loaded. Up to 32 multimedia files can be stored for use with this application. MediaPlayer includes standard controls, such as play, fast forward, rewind, stop, pause, and record. MediaPlayer supports a wide variety of audio, video, and still graphic formats including QCP, MPEG Audio Layer 3 (MP3), Musical Instrument Digital Interface (MIDI), BREW Compressed Image (BCI), Bitmap (BMP), and Packet Mode Data (PMD), which contains both audio and video.)

边缘检测，用matlab编程。边缘检测是图像处理和计算机视觉中的基本问题，边缘检测的目的是标识数字图像中亮度变化明显的点。图像属性中的显著变化通常反映了属性的重要事件和变化。(Edge detection, using matlab programming. Edge detection is an image processing and computer vision in the basic problems, edge detection is to identify the purpose of the digital image brightness variations obvious point. Image attribute significant changes usually reflect important events and changes in properties.)
