matlab处理图像的一些基本方法。其中有一部分mex程序需要安装编译

Image Contours

	The ALEX image contour anlysis can be performed in Automatic
	or Manual mode and the image contour matrix C can be saved
	in a file (Matlab or ascii format).
	
	- Automatic
	  The number of contour line can be specified. No more than 10
	  are allowed.
	- Manual
	  The levels of each contour line can be specified. The number
	  of contour lines in this case is equal to the number of levels
	  specified. Values higher or lower the image zrange will be dropped.
	  Performing the contour analysis in Manual mode but with no 
	  level values in the editor, an automatic contour analysis
	  will be done and the resulting levels will be sended
	  to the editor.
	  
	The Image flag allows to make the image visible or not.
	The Labels flag allows to display labels that identify the contour
	level.
	The Filled flag determines if the contours will be filled with
	the same color as the lines.
	
	The line parameters as well as the text parameters can be modified
	by the Options menu command. By default the lines color will be
	selected from the Extramap global matrix as well as for the labels.
	
	The Execute push button computes the contours with the specified
	parameters.
	The Clear push button clear the lines, labels, and the global matrix
	C that contain the last contour calculation.
	
	The Autoname flag determines the file name of the file to save.
	If on the extansion 'Fcontourext' defined in the alex m file
	will be appended to the image file name. If off a file name will
	be asked through the getfile utility.
	
	The Ascii file flag determines the file format.
	
	The Save push button saves the C global variable with the
	specified format and name.
	
	The Done push button clear the lines, labels, and C
	and close the command box.
