Introduction Security is a major aspect in todays life…

Every where in every field we need to be secure or provide

security so as to avoid any major losses…

Our project is based on security that is used to monitor the moving objects and store the images …

notify the owner about the slight changes by sending a message to the owner on his/her mobile phone …

For this we are making use of BACKGROUND SUBTRACTION METHOD

Background subtraction: background subtraction is the process of

separating out foreground objects from the background in a sequence of image frames. 

Background subtraction is a widely used approach for detecting moving objects from static cameras.

FUNDAMENTAL LOGIC

Fundamental logic for detecting moving objects from the difference between the current frame and a reference frame, called “background image” and this method is known as FRAME DIFFERENCE METHOD

CHALLENGES!!

challenges are associated with background modeling.

Dynamic backgrounds Gradual illumination changes Sudden illumination changes Shadows Another challenge is that many

moving foregrounds can appear simultaneously with the above non-static problems.

DIFFERENT BGS ALGORITHMS

Name Background subtraction algorithm

CB codebook-based technique in the paper

MOG mixture of Gaussians by Stauffer & Grimson (1999)

KER and KER.RGB* non-parametric method using Kernels by Elgammal et al. (2000).

UNI unimodal background modeling by Horprasert et al.(1999).

The goal: detecting moving object by a low-cost intelligent mobile phone-based video surveillance solution using background subtraction .

Existing System CCTV cameras are used.

There is a need for human to interact for knowing about the changes in the current surveillance systems.

It is not a fast secured monitored due to the time delay taken for human interaction.

Due to time delay there is a problem in updating of information.

Disadvantages

The various disadvantages of Existing System are listed below :

Highly hardware cost so cost effective and Less secure.

Needs human interaction for monitoring.

Lacks computation capability while monitoring

Proposed system

The system provides a low-cost intelligent mobile phone-based video surveillance solution using moving object recognition technology.

A self-adaptive background model that can

update automatically and timely to adapt to the slow and slight changes of natural environment is detailed.

the mobile phone will automatically notify the central control unit or the user through SMS or other means

Here svm and canny edge detection combined

Advantages

Low maintenance cost

The key of this method lies in the initialization and update of the background image/video.

Effective method to initialize the background, and update the background in real time.

This system usage for capture accurate image/video.

Description

Background modeling and subtraction is a natural technique for object detection .

We propose a pixel wise background modeling and subtraction technique using multiple features, where generative and discriminative techniques are combined for classification.

•A pixel wise generative background model is obtained for each feature efficiently and effectively by Kernel Density Approximation (KDA).

•Background subtraction is performed in a discriminative manner using a Support Vector Machine (SVM) over background likelihood vectors for a set of features.

The proposed algorithm is robust to shadow, illumination changes, spatial variations of background.
