Description: The application works with non-compressed grayscale AVI files. Run mainGUI.p. Load AVI file first using "Load". To process the next frame use "Step". To run the application until stop, use "Run" and "Stop". You can draw the tracking object using mouse at any step. You can use the function on_threshold separately:
thresholded image = on_threshold(double( grayscale image ),1,number of thresholds)
thresholds value = on_threshold(double( grayscale image ),0, number of thresholds)
All the code provided is written in Matlab language (M-files and/or M-functions), with no dll or other protected parts of code (P-files or executables). The code was developed with Matlab 14 SP1. Matlab Image Processing Toolbox is required. Platform: |

Description: Description: This Program Performs the following:
(1) Animates the movement of a Billiard Ball on a table that has a surface friction (mu) and coefficient of restitution (e) for the sides and saves it as an AVI file.
(2) Outputs series of rows and columns that displays the stream data of (Time),(X),(Y),(V), and (th) to screen.
(3) Outputs the initial X-Y coordinates along with the final coordinated when the speed of the ball reaches zero.-Description: This Program Performs the following: (1) Animates the movement of a Billiard Ball on a table that has a surface friction (mu) and coefficient of restitution (e) for the sides and saves it as an AVI file.

Description: This library contains helper functions to read image frames into matlab from Video
file using DirectShow. This library has borrowed codes from Ashwin Thangali s
"DirectShow (DirectX) based AVI file reader", and it can read multiple video formats besides avi.
Features:
a) can read frames from rmvb, avi, etc.
b) handles most codecs installed on the system
d) its implementation is only based on the IMediaDet interface
-- Depending on your Matlab version, the .mexw32 files may need to be renamed as .dll
-- The library usage is as follows,
[avi_hdl, avi_inf] = dxVideoOpen(avi_filename)
pixmap = dxVideoReadMex(avi_hdl, frame_num)
img = reshape(pixmap,[avi_inf.Height,avi_inf.Width,3])
dxVideoCloseMex(avi_hdl)
-- recompile the library
I have compiled the code with the DirectShow lib in Microsoft DirectX 9.0 SDK Update (December 2004)
-- known limitation
a)only works for windows :(
b)may be slow for big image frames and some codecs. -This library contains helper functions to read image frames into matlab from Video

Description: 功能列表= mmwrite(文件名,选择... ...)
mmwrite是能写的AVI,WMV,的WMA,ASF文件。对于AVI文件,您可以选择从现有的编解码器压缩的音频和视频流。
对于WMV,WMA和ASF的编码默认为16位的Windows Media 9率为44100Hz立体声为98%质量的音频和Windows媒体视频9 98
质量。质量可以指定音频和视频。
环绕声,似乎只与AVI和多通道编码不支持。编写任何其他文件类型不支持。本使用Windows的DirectX基础设施,以便其他操作系统是出于运气。
输入:
    文件名:这一定是第一个参数,并指定文件名写。
    影片结构:视频结构相匹配的mmread输出。在最低限度,必须有4个领域的“框架”,“时代”,“高度”和“宽度”。该“框架”字段必须是一个结构与一个字段数组“的CDATA”的原始框架,它包含由彩色编码的数据宽度高度(3)UINT8s。钍-function list = mmwrite(filename,...options...)
mmwrite is able to write AVI,WMV,WMA,ASF files. For AVI files you can choose from the available codecs to compress the audio and video streams.
For WMV,WMA and ASF the encoding defaults to Windows Media 9 44100Hz 16bit stereo 98 quality for the audio and Windows Media 9 Video with 98
quality. The quality can be specified for both audio and video.
Surround sound only seems to work with AVI and multi-pass encoding is not supported. Writing any other file type is not supported. This uses Windows DirectX infrastructure, so other OSs are out of luck.
INPUT:
filename: This must be the first parameter and specifies the filename to write.
video structure: The video structure matches the output of mmread. At a minimum it must have 4 fields "frames", "times", "height" and "width". The "frames" field must be a struct array with a field "cdata" that contains the raw frame data encoded as height by width by color(3) as UINT8s. Th Platform: |

Description: Real time optical flow, and video processing, with support for camera input in Matlab.-Start by running "runMe.m"
Supports input through:
a) synthetically generated test images
b) reading avi-file
c) camera input (requires image aquisition toolbox)
Calculates optical flow by 4 different local methods(all moment based), 2 implementations of Lucas and Kanade, and 2 implementations of point-line flow.
Can process easily hundreds of frames per second on a laptop for resolution 200x200 images. Platform: |

An AVI file is read and it is decomposed into R, G and B components. Various operations are carried out and the moving objects are detected. Thresholds at various phases are decide the possibility of identifying the moving object of certain sizes. Moving objects also tracked in it. MATLAB is used for implementation of the algorithm. The algorithm is tested with input avi format video files consisting of 120 frames. Various applications of these algorithms are studied and implemented. Main focus is given on (unmanned aerial vehicle) UAV based and automatic traffic estimation applications) Platform: |
