Processing Video Examples

For my interactive piece, I have analysed some examples that can be relevant towards the creation of my piece. It is important that I understand the programming language used, and that am capable of re-working it myself. There are those that program from scratch and those which hack examples together. Hacking examples together is a programming technique that some use, the advantages of this is that it is quicker and allows ideas to be more complex for those which are not that advanced in programming. However, the disadvantages are that if you don’t understand it, then mistakes can easily be made and it may be hard to resolve if the programming language is not fully understood. The advantages of programming from scratch is that it means your programming knowledge is more developed, meaning you can create complex ideas of which you can resolve errors more easily. However, the disadvantages are that it can take a lot longer as you will be writing out code that sometimes is already easily accessible to use. Therefore, if I do choose to use one of the following examples, it is important that I fully understand the code, which I will evident through the various sketches I have programmed and presented on my blog. If I decide to use one of the examples, it would just form a bit of my piece as I then need to use object orientated programming to create an array of gravitating objects, showing I have the ability to both hack and program. I will go on to analyse each example, understand and edit the code and experiment with trial and error.

Brightness Thresholdingbrightness thresholding v2

This is my favourite example, and I may incorporate it into my piece. Initially, the threshold was lower and therefore the figure isn’t that clear, however by changing the thresholding and positioning of the camera I was able to capture a black silhouette on a white background. Next, I need to go on to add objects the piece, and program it so when they reach a black pixel they move up and when they reach a white pixel they descend.

Motion Detection

motion detection v2

This example detects motion and produces a black outline around a moving figure. It works well, and I like the figure effect. However, it will be harder to program the objects as the black pixels are not as bold and clear as the example above.

Brightness Mirror

brightness mirror v2I like the effect of the grid of squares and think this looks very good and unique. Originally, the size was smaller which I don’t think worked as well, so I adjusted the size of the squares. When adding falling objects to this example, it could come across as being quite confusing and distorted but I think that this is a good back-up example that I could use.

Next, I will go on to experiment further with object orientated programming and will add an array of descending objects to the brightness thresholding example. I will experiment with different objects: shapes, figures, words or graphics, to see which works and looks best.
