Computer Vision Project – Tracking Ring

This is the first step of my”people tracker” on Processing.

I have to improve the ‘picking the bigger glob’ and make it follow the object closer to the last detection position, also I want to implement a ‘natural background remover’ and a simple user interface.
As described in the video, I can use the mouse click to select an color and the keyboard arrows to set the tolerance for this color, smoothing the glob region.

I couldn’t work with the OpenCV, so it’s another generic library. Actually i spent more time making the camera+Processing+Java+library work then writing a code. The library I used is this!

The aim of this exercise was to use computer vision. Computer vision is a complete field in itself. It has the power to take information from images or videos by complex methods of pixel analysis and etc. It has produced works ranging from art like display to automated robots. The xbox kinetic is an application of computer vision.

So my idea was to use computer vision to draw and trace the motion of a wheels on a canvas. I was already doing an exercise in fabrication class, to use laser cutter and make various wheels, and then look at their motion. So my intention was to capture the motion of these wheels and draw it by using a computer vision sketch in processing . Below are few ideas that i sketched to see how the drawing should look like.

Lucky i come across an sketch in open processing (link) that tracks a specific selected color from camera input.

Now all i needed to do is to modify the code so that it tracks and it draws at the same time and does it according to required display.

AntiMap Workshop / Data visualization

Using the Antimap application we are able to record a data file representing our journey.
The csv. file contains information such as your position ( latitude and longitude), your
orientation towards the north (compass), data representing your speed in kilometers per
hour, direction and time of the journey measured in milliseconds.
My intention was to create a visual representation of each piece of data distinctly, so it
would be easier to understand that the final trajectory contains all the above-mentioned
data. From a more narrative and static representation of each data set in the beginning
of the workshop I decided to follow more abstract way of representation, using the simple
geometry of lines and shapes, playing with colors and transparency.
The final visualization draws the lines from data points like threads, weaving each
data line into the trajectory of movement. This forms a visual fabric covering the whole
area of canvas during a period of time. I used the csv. files from two distinct sources
in order to test a diverse visual qualities, resulting in repetitive but different patterns.

antiMap exercise. Home

What is your home’s relation with you? Is it missing you when you away, anticipate when you are coming back or turning to it’s direction? Making this exercise I’ve tried to visualize it.

Sounds of Journey

The idea is simple to translate the journey of a person into a continuous stimulation of moods and emotion. Sounds the resultant of this stimulation is produced by changing speed, direction,relative distance to A & B and the compass “look direction” to produce a multitrack “song” that with time, the user can play with it’s composition.

This is done by using an app called antimap, which captures your position, speed, direction to the compass, while you are rooming in the city. Processing is use to make a sketch which uses these data and translates it into into a visual & sound experiences. So you not only see put also hear his or her journey.

So with a this basic concept we went to drawing board and started sketching how the display would look like and what kind of environment the object would be. The object is just a representation of a persons journey.

So We (Lucas De Sordi & me) found a somehow similar sketch in open processing website (link here). We used this sketch as a reference for our idea because it uses the potions of mouse to produce a certain kind of sound. we liked the idea of a certain kind of sound.

We first made a sketch that visualizes the movement of mouse to produce sound. This was to test the variation and range of sounds that can be produced. Later this movement of mouse would be replaced be the movement of humans in the city.

In next step (major coding) the data from antimap, the visual display and the production of sound. All these happen written into a simple code. Here are a few screen shots.

Screen Shots

Since the sketch would not upload to the blog with its data (for now). we made a video.

ok from start we wanted to have a more zen like peaceful melodies sounds, Since the example for the sound was not the right example it was hard for u the change it at this moment, secondly the sound was going to be produced by the direction of once head and this event would also be shown on the display.
