Who am I?

● Chief System Architect of

● I teach Network Security and Linux System Administration

Why am I talking about computer vision?

I have a car :)

I have a car :)I have a Raspberry Pi

I have a car :)I have a Raspberry PiI know programming

So what did I wanted?

➢ Car High/Low beams detection

➢ Car High/Low beams detection➢ Car detection

➢ Car High/Low beams detection➢ Car detection➢ brand

➢ Car High/Low beams detection➢ Car detection➢ brand➢ position

why position?

➢ Car High/Low beams detection➢ Car detection➢ brand➢ position

why position?➢ to point the LIDAR in that direction and get the distance to that car

➢ Car High/Low beams detection➢ Car detection➢ brand➢ position

why position?➢ to point the LIDAR in that direction and get the distance to that car

➢ Traffic signs detection

How I started all that?

How I started all that?

➢ NO GOOGLE was involved in these steps :)

How I started all that?

➢ NO GOOGLE was involved in these steps :)➢ ffmpeg for grabbing frames from rtsp stream

How I started all that?

➢ NO GOOGLE was involved in these steps :)➢ ffmpeg for grabbing frames from rtsp stream➢ ImageMagick for converting them to grayscale

How I started all that?

➢ NO GOOGLE was involved in these steps :)➢ ffmpeg for grabbing frames from rtsp stream➢ ImageMagick for converting them to grayscale➢ Then read the docs of ffmpeg and used it for grayscale

Open Source computer vision

OpenCV - http://opencv.orgJeVois - started Jan.2017

What can you do with CV?

➢ Object detection

➢ Object detection➢ Face recognition

➢ Object detection➢ Face recognition➢ Predefined shapes eg. square, triangle and etc.

➢ Object detection➢ Face recognition➢ Predefined shapes eg. square, triangle and etc.

➢ Pre-trained image, like apples, squirrels, dogs, traffic signs and etc.

Now that you have CV...

How can you use it in your own projects?

Detect a face call the secretary do additional match for face recognitioning

Detect lights turn off high beams turn on street lights

Detect an object alert the driver prevent the robot from hitting that object trigger OCR over that part of the image trigger OCR and store the car number

Detect a gesture dim the lights turn on the heating call a friend turn on/off some device

How can you start?

➢ JeVois is a nice, easy way

➢ JeVois is a nice, easy way➢ Raspbery Pi + Pi Camera

➢ JeVois is a nice, easy way➢ Raspbery Pi + Pi Camera➢ Home PC + USB camera

Some examples
