Interactive painterly rendering with artistic error correction

Interactive Painterly Rendering for Mobile Devices

“…By using the method described in the previous section, we can obtain painterly rendering that is similar to the results from previous works [7,6,12]. Rather than performing the process automatically, we offer an interactive approach to the rendering.…”

“…Our study is based on [12]'s algorithm for painterly rendering. This algorithm automatically generates painterly images using a brush-stroke texture database and a photomosaic method [13,10,9].…”

“…This algorithm automatically generates painterly images using a brush-stroke texture database and a photomosaic method [13,10,9]. However, users cannot participate in the painting process with [12]'s method, apart from choosing the input image and a limited number of rendering settings. To enhance user participation, we propose an interactive algorithm for painterly rendering in order to facilitate the direct involvement of the user during the painting process.…”

“…For our proposed algorithm, however, we employ [12]'s method to determine the most suitable brush stroke from a stroke-texture database and map it to the canvas. First, we sample the color of the input image at a point selected by the user through a touch interface in order to allow the user to choose the color of the brush stroke.…”

“…The proposed algorithm is based on previous methods [12], and it allows users to generate plausible painterly artwork easily. In Section 2, we describe our enhanced algorithm for painterly rendering.…”
