Abstract
The processing of two-dimensional chromatic images of low resolution is based on principles of mathematical representation of coordinates in a Cartesian plane, where functions with position variables (x and y) are used to model the illumination intensity of each pixel, based on the combination of each primary color: red, green and blue (RGB). It should be mentioned that the resolution depends directly on the number of pixels processed, which is why, for the execution of the present investigation, low resolution test images have been used in order to be represented in a size of 64 x 64 pixels.
In this sense, the present work covers initially the processes of conceptualization of the electronic model based on a bibliographic analysis of the free hardware platforms, mainly of the Arduino embedded system and its different shields or complementary elements, then the process of mathematical representation of each of the pixels of the images selected by the intensity scales for each primary color (Red, Green and Blue), which are then incorporated into the coding of the electronic system under Language C; Finally, the images are reproduced in RGB Led arrays, where each pixel is a Led (64x64).
