paper proposes real time Face detection for an ATM security using Raspberry Pi
and Image Processing. Today image processing is used in various techniques.
Raspberry Pi is a basic embedded system, which itself is a minicomputer of
credit card size and is of a very low price. The system is programmed in python
language. The Raspberry Pi camera module is used to capture images once the
motion is detected by the PIR Sensor. The captured image is checked with the
database images. If the image is matched with any of the database images it
gives access to the user else the captured image is sent to the mail-id and SMS
alert is sent to the authorised mobile number.

image processing is a form of signal processing where the input is an image,
or video frame, the output of an image processing may be either an image or
a video frame or a set of characteristics or
parameters related to the image. The Raspberry
Pi is based on the Broadcom BCM2835 system on a chip
(SOC) which includes an
ARM1176JZF-S Core (ARM V6K)700 MHz CPU processor,
Broadcom Video Core IV GPU
having 17 pins, 3.5W of power, and 512 MB of RAM
memory. The Raspberry Pi system has
Secure SD card reader (models A and B) or Micro SD
card reader (models A+ and B+) sockets
media and persistent storage. The system
provides Debian Linux operating system
Raspbian image for download. Python is used as main
programming language for raspberry
Concept of Image Processing:
general, any digital image processing algorithm consists of three stages:
input, processor and output. In the input stage image is captured by a camera.
It sent to a particular system to focus on a pixel of image that’s gives, its
output as a processed image.

Methodology / Flow chart:
However,they are many techniques for safety check,we
think these face recognition also one of the important tool.the image
processing is mainly done by the raspberry pie which is the powerful tool for
all these and it was successfully implemented.
