چکیده
Computational photography is an emergent multidisciplinary field that combines topics in optics, computer graphics, image and signal processing. The objective is usually the development of new algorithms or systems to capture images overcoming the limitations of conventional techniques. Images are not simply captured as 2D projections of a scene, they are rather coded before reaching the sensor in a way that can later be decoded and interpreted. This coding-decoding process allows to recover information lost in the traditional capture process. In the present text we will go through the fundamentals and will then offer some examples of recent research projects, a representative cross-section covering some of the most relevant results produced. This cross-section will include plenoptic imaging, coded apertures, novel analysis of light transport and recent advances in ultra-fast imaging, as well as an introduction to computational displays.
