Abstract
Abstract We present an image‐based algorithm for interactive rendering depth‐of‐field effects in images with depth maps. While previously published methods for interactive depth‐of‐field rendering suffer from various rendering artifacts such as color bleeding and sharpened or darkened silhouettes, our algorithm achieves a significantly improved image quality by employing recently proposed GPU‐based pyramid methods for image blurring and pixel disocclusion. Due to the same reason, our algorithm offers an interactive rendering performance on modern GPUs and is suitable for real‐time rendering for small circles of confusion. We validate the image quality provided by our algorithm by side‐by‐side comparisons with results obtained by distributed ray tracing.
