Light Field (LF) imaging is a multimedia technology that can provide more immersive experience when visualizing a multimedia content with higher levels of realism compared to conventional imaging technologies. This technology is mainly promising for Virtual Reality (VR) since it displays real-world scenes in a way that users can experience the captured scenes in every position and every angle, due to its 4-dimensional LF representation. For these reasons, LF is a fast-growing technology, with so many topics to explore, being the LF inpainting the one that was explored in this dissertation. Image inpainting is an editing technique that allows synthesizing alternative content to fill in holes in an image. It is commonly used to fill missing parts in a scene and restore damaged images such that the modifications are correct and visually realistic. Applying traditional 2D inpainting techniques straightforwardly to LFs is very unlikely to result in a consistent inpainting in its all 4 dimensions. Usually, to inpaint a 4D LF content, 2D inpainting algorithms are used to inpaint a particular point of view and then 4D inpainting propagation algorithms propagate the inpainted result for the whole 4D LF data. Based on this idea of 4D inpainting propagation, some 4D LF inpainting techniques have been recently proposed in the literature. Therefore, this dissertation proposes to design and implement an LF inpainting application that can be used by the public that desire to work in this field and/or explore and edit LFs.
