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: 该代码在matlab环境下实现人脸检测。核心代码采用c语言编写，可直接用于matlab环境下。目前，该代码可有效检测视频或图像中的单个人脸，可以作为研究者入门和学习编写代码之用。-This code written in Matlab is used to realize face detection. The key code is written in C and can be applied in Matlab environment directly. Recently, it can only detect one face existing in video or image. So, it can be used to learn how to write code for face detection in Matlab environemtn. Platform: |

Description: 静态图像显著性分析程序，利用matlab开发。加州理工三位教授所写。-Software] Saliency Map Algorithm : MATLAB Source Code
Below is MATLAB code which computes a salience/saliency map for an image or image sequence/video (either Graph-Based Visual Saliency (GBVS) or the standard Itti, Koch, Niebur PAMI 1998 saliency map). See the included readme file for details. I also have a newer, simpler version implementing only the Itti algorithm (see simpsal/readme.txt).
Please try it out and email me if you have any questions.
Download:
Please select one of the following to download:
[gbvs.zip]
This package includes an implementation of the full GBVS algorithm. It also lets you compute an Itti, Koch, Niebur saliency map. It includes a function for computing the ROC score between eye-movements (provided as x,y fixation points) and a saliency map, and a function for displaying a saliency map overlayed on top of an image (as in the screenshot below).
Right after you download the zip file, you must change into the gbvs/ directory and run:

Description: Orthogonal frequency division multiplexing (OFDM) is becoming the chosen
modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
countless applications. Here, at the Georgia Institute of Technology, one of such
teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part
of the Georgia Center for Advanced Telecommunications Technology (GCATT).
The purpose of this report is to provide Matlab code to simulate the basic processing
involved in the generation and reception of an OFDM signal in a physical
channel and to provide a description of each of the steps involved. For this purpose,
we shall use, as an example, one of the proposed OFDM signals of the Digital
Video Broadcasting (DVB) standard for the European terrestrial digital television
(DTV) service.-Orthogonal frequency division multiplexing (OFDM) is becoming the chosen

Description: 图像处理 并行处理 matlab Since images can be represented by 2D or 3D matrices and the MATLAB processing engine
relies on matrix representation of all entities, MATLAB is particularly suitable for implemen‐
tation and testing of image processing workflows. The Image Processing Toolbox
™
(IPT)
includes all the necessary tools for general-purpose image processing incorporating more than
300 functions which have been optimised to offer good accuracy and high speed of processing.
Moreover, the built-in Parallel Computing Toolbox
™
(PCT) has recently been expanded and
now supports graphics processing unit (GPU) acceleration for some functions of the IPT.
However, for many image processing applications we still need to write our own code, either
in MATLAB or, in the case of GPU-accelerated applications requiring specific control over
GPU resources, in CUDA (Nvidia Corporation, Santa Clara, CA, USA).-the first part is dedicated to some essential tools of the IPT that can be used in
image analysis and assessment as well as in extraction of useful information for further
processing and assessment. These include retrieving information about digital images, image
adjustment and processing as well as feature extraction and video handling. The second part
is dedicated to GPU acceleration of image processing techniques either by using the built-in
PCT functions or through writing our own functions. Each section is accompanied by MAT‐
LAB example code. Platform: |
