How to Use VideoFinder 

Initially, you will need the following steps for video matching:

	0. Initialization (Only Once after starting the software)
	1. Select Library (Source button)
	2. Get Library Signatures (source.txt)
	3. Select Key (Key button)
	4. Get Key Signatures (key.txt)
	5. Create Library File (lib1.txt)
	6. Load Library (lib1.txt)
	7. 1:N Matching (Match/1:N Match menu item)
	8. First Results (2nd F button)
	9. Next Results (2nd > button)

Later, you do not have to create a library each time:

	0. Initialization (Only Once After Starting the Software)
	6. Load Library (lib1.txt)

	3. Select Key (Key button)
	4. Get Key Signatures (key.txt)
	7. 1:N Matching (Match/1:N Match menu item)

	3. Select Key (Key button)
	4. Get Key Signatures (key.txt)
	7. 1:N Matching (Match/1:N Match menu item)

	…



0. Initialization (Only Once After Starting the Software)

	This step initializes the software. This step is implemented by clicking:

	·	“Beginner/0. Initialization (Only Once)” menu item, OR
	·	“Init” button. 

1.	Select Library (Source button)

	A video clip is converted into a video clip signature. A set of video clip signatures forms a library. 
	A set of video clips will be placed in a directory and the directory path 
	(for example, “c:\abc\def\”) will be entered into the VideoFinder.

	This step selects a video clip directory. This step is implemented by clicking:

	·	“Beginner/1. Select Library (Source button)” menu item, OR
	·	“Source” button. 

	The video clips in the selected directory will be displayed in the second picture box (labeled ‘Library’). 
	Use the “Play” and “Stop” buttons to play the video clip. 
	Use the “F” button to select the First video in the directory; use the “>” button to select the next video clip; 
	and use the “<” button to select the previous video clip.



2. Get Library Signatures (source.txt)

	This step converts all video clips in the selected directory into signatures and saves them to the file, 
	“source.txt”. This step is implemented by clicking:

	·	“Beginner/2. Get Library Signatures (source.txt)” menu item, OR
	·	“Signature/Library Signatures” menu item. 

3. Select Key (Key button)

	A key is a newly obtained video clip. The video clip is converted into a signature. The key 
	(for example, “c:\abc\def\ghi.avi”) will be entered into the VideoFinder. 

	This step selects a key. This step is implemented by clicking:

	·	“Beginner/3. Select Key (Key button)” menu item, OR
	·	“Key” button. 

	The selected key will be displayed in the first picture box. Use the “Play” and “Stop” buttons to play 
	the video clip.

 

4. Get Key Signatures (key.txt)

	This step converts a key video clip into a signature and saves them to the file, “key.txt”. 
	This step is implemented by clicking:

	·	“Beginner/4. Get Key Signatures (key.txt)” menu item, OR
	·	“Signature/Key Signature” menu item. 

5. Create Library File (lib1.txt)

	Before matching, you will need to select a library and load it to the VideoFinder. The library to be 
	loaded is fixed to the file, “lib1.txt”. We have created a library file, “source.txt”; now we will 
	simply copy it to the loading-library file, “lib1.txt”.

	This step is implemented by clicking:

	·	“Beginner/5. Create Library File (lib1.txt)” menu item, OR
	·	“Library/Copy source.txt to lib1.txt” menu item. 

6. Load Library (lib1.txt)

	Before matching, you will need to select a library and load it to the VideoFinder. This step is implemented 
	by clicking:

	·	“Beginner/6. Load Library (lib1.txt)” menu item, OR
	·	“Library/Load (lib1.txt)” menu item. 

7. 1:N Matching  (Match/1:N Match menu item)

	“1:N Matching” (read as 1 to N matching) compares “1” (i.e., the new video clip) with “N” 
	(i.e., the previously stored video clips).  This step is implemented by clicking:

	·	“Beginner/7. 1:N Matching” menu item, OR
	·	“Match/1:N Matching” menu item. 



8. First Results (2nd F Button)

	The 1:N matching results are also displayed in the third picture box (labeled ‘Results’). 
	To select the first retrieved video clip, use: 

	·	“Beginner/8. First Results (2nd F Button)” menu item, OR
	·	Second “F” button. 

	Use the “Play” and “Stop” buttons to play the video clip.

9. Next Results (2nd > Button)

	The 1:N matching results are also displayed in the third picture box (labeled ‘Results’). 
	To select the next retrieved video clip, use:
 
	·	“Beginner/9. Next Results (2nd > Button)” menu item, OR
	·	Second “>” button. 

	Use the “Play” and “Stop” buttons to play the video clip.
