Description: There are many approaches for motion detection in continuous video streams. All of them are based on comparison of current video frame with one from the previous frames or with something that we ll call background. In this article I ll try to describe some of the most common approaches. In describing the algorithms, I ll use an image processing library I ve described in my previous article. So, if you are common with it, it will only help. The demo applications support the following types of video sources: AVI files (using Video for Windows, interop library is included) updating JPEG from internet cameras MJPEG (motion JPEG) streams from different internet cameras MMS Stream - Microsoft Media Services local capture device (USB cameras or other capture devices).-There are many approaches for motion detection in continuous video streams.

Description: This toolbox provides some functions for manipulating planar, closed splines to implement image or video segmentation by means of deformable (or active) contours. Contour topology is managed in a way that should allow changes similar to what can be observed with level sets (merging and splitting but no hole creation). Several objects can be segmented simultaneously in several frames. -This toolbox provides some functions for m anipulating planar. closed spline to implement image or video segm entation by means of deformable (or active) con tours.

Description: 智能交通监视系统中基于边缘的运动目标提取算法
本文的算法是基于C++和OPEN CV实现的，要运行此程序首先要安装这两个软件
由于本文在采集图像时用到的视频图像较大 ，要100多兆，所以演示程序采用另一个视频，以观其效果
本程序中采用视频序列的前四十帧的奇数帧提取出背景边缘，用参数backframes来控制，backframes/2
即是采用的帧数。
cedge_thresh1和cedge_thresh2来控制做背景检测是用到的CANNY算子的两个阈值。
edgesum_thresh控制来背景边缘提取时去掉运动目标边缘的阈值。

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: Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos. Platform: |

Description: 以镜头光圈分类 镜头有手动光圈（manual iris）和自动光圈（auto iris）之分，配合摄象机使用，手动光圈镜头适合于亮度不变的应用场合，自动光圈镜头因亮度变更时其光圈亦作自动调整，故适用亮度变化的场合。-This paper describes an end-to-end method for extracting
moving targets from a real-time video stream, classifying
them into predefined categories according to imagebased
properties, and then robustly tracking them. Moving
targets are detected using the pixel wise difference between
consecutive image frames. A classification metric is applied
these targets with a temporal consistency constraint
to classify them into three categories: human, vehicle or
background clutter. Once classified, targets are tracked by
a combinationof temporal differencing and templatematching. Platform: |
