Recently, an emerging light field imaging technology, which enables capturing full light information in a scene, has gained a lot of interest. To design, develop, implement, and test novel algorithms in light field image processing and compression, the availability of suitable light field image datasets is essential. In this paper, a publicly available light field image dataset is introduced and described in details. The proposed dataset contains 118 light field images captured by using a Lytro Illum light field camera. Based on their content, acquired light field images were classified into ten different categories with various features covering wide range of potential usage, such as image compression and quality evaluation.
