Objectives:
SURVEC is a tool wich enables to use webcams (1 or 2) for monitoring basically a screen but also everything coming from webcam pictures. The software enables to trigger alarms when a change is detected in a Region Of Interest (ROI) in the webcam video stream. The detection could be defined on 4 differents types:

• Color: the average color of the ROI is extracted and compared to a target color
• Text: the text of the ROI is readed with an OCR technology (Tesseract) and compared to the target text
• Numeric: works like the text but with a numerical conversion and a comparison to a target value (comparison could be equals, greater than or lower than)
• Symbol: the symbol is a picture recorded from an initial ROI. The comparison works with a comparison image to image with sturctual similarity process (SSIM).

Dependances
SURVEC needs others libraries for working:

• OpenCV2.4.10 : used for image processing
• Tesseract3.02 and Leptonica1.71 : used for OCR processing
• QT5 : used for GUI

Licences
SURVEC licences is LGPL v2.
