The proposed algorithms are fast, accurate and do not need to generate Subaperture Images (SAIs) or Epipolar Plane Images (EPIs) which is capital for focused plenoptic cameras. Also, the resolution of the resulting depth map is the same as the rendered image. We show results of our\npipeline on the Georgiev\u2019s dataset and real images captured with different Raytrix cameras.<\/span> \n<\/pre>\n<p><span class=\"fontstyle0\">&#8220;<em>An Image Rendering Pipeline for Focused Plenoptic\u00a0Cameras<\/em>&#8220;, M.
