description
In this presentation, I spoke about the main idea of the library 'MyImageLibrary', displaying the central core of this proposed framework. The library is composed of a core of generic representation of images (RGB or RGBA type), a core of spatial filtering, a core for manipulating borders (used mostly by the spatial filter) and a core of similarity metrics. The cores related to spectral filters and metrics for evaluating the quality of images, still in development, should be added in an upcoming release. The implementation of 'MyImageLibrary' has, in principle, purely didactic intent.
