Algorithms Implementation – Motion Detection Edge Input image Detection in i. Phone Edge Detection Edge Extraction Compare the difference Identifiy Motion

Algorithms Implementation – Motion Detection Face Input image Detection in i. Phone Face Detection Face Extraction Face Recognition Identifiy Human Motion

Algorithms Implementation – Motion Detection Pixel Difference Optimization

Optimization of Pixel difference detection Pixel Difference Level represents the sensitivity of the difference between two pixels

Optimization of Pixel difference detection Motion Points represents the number of pixels per particular area to compare with

Optimization of Pixel difference detection Motion Level threshold level indicates the percentage of the number of pixels difference counted over total “Motion Points”

Comparison of motion detection algorithms Pixel Difference Detection Edge Detection

Comparison of motion detection algorithms Algorithm Time to identify motion occurred Accuracy CPU/Memory Usage Edge Detection 1 – 2 second Low Medium Face Detection 3 – 5 second Medium High Pixel Difference (After optimization) Less than 1 second High Low Win !

Algorithms Implementation – Movement Detection

Algorithms Implementation – Surveillance Motion Start Surveillance Detection Mode Start Movement Detection Start Image Processing of Pixel Difference Detection Monitoring Mode Start Surveillance Send Email Notification regularly

Notification design – Email Notification SMTP Server Sender’s Outgoing SMTP Server Photo Attachment Receiver’s Incoming SMTP Server

Notification design – Alert Notification AVFoundation AVAudio. Player *_player; // Load the audio file NSURL *file. URL = [[NSURL alloc] init. File. URLWith. Path: [[NSBundle main. Bundle] path. For. Resource: @"Alarm" of. Type: @"m 4 r"]]; _player = [[AVAudio. Player alloc] init. With. Contents. Of. URL: file. URL error: nil]; if( is. Alarm. On && is. Motion. Detection. Mode) { [_player play]; }
