RoiCounters C++ Tango device

RoiCounters is a post process specific device

The Region-of-Interest to Counter operation is very useful to provide online statistics on some image areas.

The operation will calculate for each acquired image the :

• the average of pixels

• the standard deviation

• the sum of pixels

• the minimum pixel value

• the coordinates (X,Y) of the minimum pixel

• the maximum pixel value

• the coordinates (X,Y) of the maximum pixel

User can configure one or many Region Of Interest (32 Rois at Maximum)

User can also configure the order of this operation in the chain of operations already defined

Properties

Property name	Default value	Type	Description
NbRoiCounters	2		Fix the number of Region Of Interest.
__x	0 0		(Origin X) for each Region of Interest.
__y	0 0		(Origin Y) for each Region of Interest.
__width	10 10		(Width) for each Region of Interest.
__height	10 10		(Height) for each Region of Interest.

Attributes

Attribute name	Read/Write	Type	Description
version	R	String	Display the Version of the RoiCounters Device.
runLevel	W	ULong	Fix the execution order of this operation in the processing chain.
frameNumber	R	ULong	The frame number on wich the ‘roi counters’ computation were made.

Dynamic attributes (for each defined Roi)

Attribute name	Read/Write	Type	Description
x	R/W	DevULong	The x coordinate of the Roi
y	R/W	DevULong	The y coordinate of the Roi
width	R/W	DevULong	The width of the Roi
height	R/W	DevULong	The height of the Roi
coordinates	R/W	DevString	The full coordinates of the Roi: take a string of 4 numbers seperated by any other character and will parse them into x, y, width and height, in that exact order.
