Video-Analysis-for-Surveillance

Analyzing CCTV videos to find timestamps of interesting events using deep learning

Description

Performed this analysis using image/video processing and deep learning algorithms.

The Project consist of three steps :

1.) Extracting frames from a video at regular intervals
2.) Detecting change in every two consecutive frames in a sequence
3.) Reporting timestamp for every change

Prerequisites

Software

Python-opencv
Tensorflow v 1.0 or later
Python 3.6.0 |Anaconda 4.3.0 (64-bit)|

Tested on Ubuntu 16.04 LTS amd64 xenial image built on 2017-09-19 8-core CPU

Installation

Simply clone the repository
Paste your video/videos in "videos" folder
Done

Running

Simply run this command from root directory.

python extract.py ./videos -o ./images --skip 75

NOTE : Video should be present in "videos" folder
: Frames will be extracted in "images" folder
: --skip = 3*FPS
: The provided video "05_05.mp4" has 25FPS , so skip = 75
