Concept

This is an experiment to change the texture of videos.
A video of audience, which comes from internal webcam of the computer, is transformed by external variables, which came from other Pure data / max patch.
The aim of this experiment is to represent a different impression while people see what they usually see in their life, by changing textures.
It is the first step of giving different look of texture by visual effects.

File

The max patch can be downloaded from here;
Media:Pixel_sampling_test_02.maxpat

Also, here is the patch I used for osc communication with other patches
Media:OSC_Network.maxpat

Methods

1. Capture a video from the webcam

Using jit.brab object, the video from a webcam can be captured and integrated with other max objects.
The captured video is sent to jit.matrix object.
In the sample patch, a large toggle button in the center of the window activates this step.


2.Generate noise maps for masking

Next to the video capture part, there are some objects to generate a monochrome nonise texture.
jit.bfg object generates actual noise, and it enables to select several types of noise.
In this patch, a simplex noise is used, but there is another noise mask using curl noise in this patch.
