声音档和Video档的读与写byMatlab 聲音檔和Video檔的讀與寫(byMatlab)作者：丁建均 國立台灣大學電信工程學研究所 1 一、聲音檔(*.wav)的讀取 •電腦中，大部分的聲音檔都是*.wav的型態•讀取：wavread •例：[x,fs]=wavread('C:\WINDOWS\Media\ringin.wav');可以將ringin.wav以數字向量x來呈現。
Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. Cite As Alfred...
current_image = readFrame(vid); edge(current_image); 動画処理は、エッジ検出を使用した例のように非常に単純な場合もあれば、前のフレーム内のオブジェクトの位置を考慮する必要がある追跡アルゴリズムのように、非常に複雑な場合もあります。 高度な動画処理の詳細については、以下の例を参照...
video = read(v,index) 只读取 index 指定的帧。 video = read(___,'native') 以 VideoFormat 属性指定的格式返回数据,并且可以包含上述语法中的任何输入参数。 创建一个视频读取器对象,并使用帧索引读取一个或多个视频帧。为示例影片文件 abc.mp4 创建一个VideoReader 对象。 v = VideoReader('abc.mp4')...
