| V.I.P.Scilab 1.0 User Guide Welcome to the image world of V.I.P.Scilab. • Installation 1.Systerm Requirements: V.I.P.Scilab 1.0 can work with any machine that has Scilab-2.7, Windows Media Player under Windows or Mplayer under Linux. We suppose that you install the player under the default path:

Windows: ¡®C:/Program Files/Windows Media Player/wmplayer.exe'

Linux: /usr/local/mplayer

And we suggest that you have 256M EMS memory, then I am sure you will run it perfectly.

V.I.P.Scilab 1.0 is for Scilab-2.7. Its interface is writen in TCL/TK, which is installed with Scilab. If TCL/TK doesn't exist, you could get it from tcl.sourceforge.net , and then install TCL/TK 8.0 or higher version.

V.I.P.Scilab 1.0 has Linux version and Windows version, which can run separately under Windows and Linux. You may find that they both have a proper colorstyle to match with its operating system for good display.

2.Installment for Windows:

Run Setup.exe of V.I.P.Scilab, and follow the installment wizard. After you finish the installment, you will find under the directory of V.I.P.Scilab, there are SIP , ImageMagick, SIP_INSTALL.txt and other files. SIP and ImageMagick are packed with Scilab, so you can use them directly without the step to download them. You should browse SIP_INSTALL.txt, which tells you how to use SIP and ImageMagick under Scilab.

3.Installment for Linux:

Unzip and untar the given package. This package does nothing more than release it under your Scilab-2.7 directory. If you want to install it manually as follow:

¡¡¡¡¡¡¡¡$gunzip ¨Cc VIPScilab.tar.gz | tar ¨Cxvf ¨C

• Getting Start

Read the User Guide in the given package. Start Scilab-2.7 and execute the file imScilab.sce under the directory of V.I.P.Scilab,then a nice and user-friendly GUI is presented before your eyes. Hope you like it.

• How to use V.I.P

1.First Step
Open image files: Pay attention to the left bottom of the main window, here we make every picture one shortcut button . Click it to open relevant image, make the image active in every processing and the brief information of the image will be shown in the message bar.

2. Filter-window

After opening a picture, you could filter it like 'menu->filter-> Thresholding->im2bw', or process it directly like 'menu->image->mode->GRAY Color'.

Having looked through the simple introduction above, you should know that the enabled image will first be processed. Suppose you have opened two pictures, and make the second picture enabled, then you open the 'im2bw' window, it will show the second picture as default.

Set data and click button 'preview' to get a view of your processed picture.

Being a special option, 'all' can filter every existing picture with the same processing.

Buttons 'Insert, default, help' are three useful buttons. Click the first button to insert your every processing step orderly in the code-editor(introduced below), the second helps you set default data in case you still are not familiar with the function, and the last shows you the function introduction .

Special Effect(only for Linux) :

The below window is different from Filter-window and video-window. It appears only under Linux , because the function 'mogrify' can now be used only under Linux. It appears when we click menu [Filter]->[Special Effect]->[Special Effect] . As the graphics show, the right part is so simple that we can know how to operate it easily. Although the left part is a little different, it's easy to use too: just choose one operation type by pressing one of the eight buttons placed above, and set the data in relevant form below.

3.Code-Editor

As an open-source software, V.I.P.Scilab offers you the ability to operate the codes directly in the code-editor window.

But it is not perfect, here you can open .sci files, .txt files and even tcl script. You can edit codes, run codes and save them. Buttons 'Find/Replace' and 'SetFont' also provide convenience to you to edit code.

4.Video Processing

From now on, you will enter the domain of video processing. Here you can process AVI format movie and play it, or choose one frame from the AVI file, then filter it like normal picture. When you want to save video streams, you should choose which frames you want to be filtered and to be saved.

Another three buttons are our special Video Processing:

• Temporal Differencing

• Background Substraction

• Demo-Moving maritime Objects detection

First two have the same usage. Choose two frames and show them separately at left label and right one, Set parameters, click 'confirm' and then check the result at left label.

The last is a independent demo, which is composed of several functions to achieve a great goal-- Moving object detection. I guarantee it will make you impressive.

• Write before use

If you find any bugs or have any suggestions, please let us know, we are glad to hear from you.
